Amended Exhibit A to Contract with GMR Aerial Surveys, Inc. d/b/a Photo Science
Scope of Work (April 15, 2009) (as amended by amendment No.2 on August 3,2009)
Photo Science will provide Monroe County with professional mapping services using a well established
methodology proven on similar projects within Florida and other similar projects throughout the United
States. The delineation and classification of each land cover type will be performed by uniquely
qualified photointerpreters who have strong backgrounds in natural resources and geography and who
have an in-depth knowledge base of land use and land cover types specific to Florida natural systems,
agricultural, as well as high density residential, commercial, and industrial areas.
The SFWMD 2004-2005 FLUCCS dataset, along with the 1991 Advanced Identification (ADID) land
cover feature class dataset referenced in the County's solicitation are ideal sources of collateral data
that will be referenced throughout Photo Science's production work flow. During the photointerpretation
process Photo Science will only reference the collateral data and not use any of the line work from
these previous mapping efforts, (Le., ADID, FLUCCS). Rather, the 2008-09 mapping effort will be
compiled using only original line work with the possible exception of shoreline data.
Photo Science will apply the County's New Potential Land Cover Categories classification summarized
below.
1. Develooed Land - Develooed Lane is comorised of areas of intensive use with much of the land
covered by structures. Examoles are dwellinas. strio develooments. industrial and commercial
comolexes. landfills. aolf courses and oarks. All imoerious surface areas below 0.5 acres will
also be included within this cateaorv.
2. Undevelooed Land - This cateaorv includes ooen . scarified. or disturbed lands which tend to
have uncertain land uses and may contain native soecies.
3. Impervious Surface: This cateaorv includes all surfaces above 0.5 acres which do not allow or
minimally allows. the oenetration of water. Examoles are buildina roofs. concrete and aSDhalt
oavements/oarkina lots and some fine arained soils such as clays.

~. Hammock: This was used to designate most of the upland and upland hammock
vegetation found throughout the Keys that is natural and generally undisturbed.
~. Pineland: an upland forest community with an open canopy dominated by the native slash pine
composed of known species.
6. Exotic: Invasive exotic species include Melaleuca, Australian Pine, Brazilian Pepper, Leatherleaf
and Sapodilla north of the seven mile bridge.
L Scrub mangrove: Typically found in the lower Keys, coastal scrub mangrove of dwarf mangrove
are dominated by known species. Plants are typically less than 5' tall.
8. Freshwater Wetland: wetland areas with either standing water or saturated soil or both where
the water is fresh or brackish composed of known species. Some Freshwater Wetlands are isolated
and therefore not subject to the MMU of 0.5 acres. Rather, photointerpreters will delineate them
without regard to the MMU.
g. Saltmarsh
10. Buttonwood
11. Mangrove : a wetland plant association subject to tidal influence where the vegetation is
dominated by Black, White or Red mangroves.
12. Beach Berm: all sandy shorelines or beach areas.

Photo Science shall capture land cover features at the minimum maooina unit (MMU) of 0.5 acres with
the exception of isolated wetlands and small hammock habitat. Isolated wetlands will be mapped at
even smaller MMU's. Smaller hammock habitat will be caotured at the MMU of .35 acres.
Photo Science proposes a vector land cover data set be compiled from source imagery at the
determined MMU. Format will be an ArcGIS Geodatabase.
-2-
Photo Science's work flow is summarized as follows: Note that Quality Assurance and Quality Control
(QA/QC) procedures will be integrated through this work flow.
. Kick-off meeting with the County
· Collect and review collateral and source imagery
. Set up computing environment
. Data preparation
. Photointerpretation (PI)
. Field work
. PI Update
. GIS Processing
. Metadata
. Thematic Accuracy Assessment
. Final Report
. County Review
. Project Close out
Photo Science will provide the County with detailed progress reports on a monthly basis.
All source materials received from the County will be controlled using a chain-of-custody documentation
procedures which will track all source materials including the required referenced materials and optional
referenced materials provided to the team by the County.
Photo Science will produce a spatially, thematically and technically accurate ArcGIS 9.3 Land Cover
geodatabase from the digital source imagery. The Land Cover dataset development will include
documentation and metadata describing the methods and products.
Photo Science will create a new land cover dataset that is correct in both classification and positional
accuracy. Photo Science will create this dataset using uniquely qualified photointerpreters who have
strong backgrounds in natural resources and geography and who have an in-depth knowledge base of
Land Cover types specific to the Florida Keys natural systems, as well as high density residential and
commercial areas. All of Photo Science's Photointerpreters assigned to this project will familiarize
- 3 -
themselves with spectral signatures associated with the project work areas to gain the necessary
knowledge to establish the decision rule criteria necessary for accurate and consistent
photointerpretation.
All of Photo Science's photointerpretation will adhere to a minimum mapping unit that meets or 0.5
acres (except wetlands isolated which will be mapped if seen on the imagery regardless of the MMU) or
other MMU defined by the County. Photointerpreters will delineate and classify Land Cover with the
appropriate classification codes by utilizing the basic photo elements of shape, size, pattern, shadows,
tone, texture, site, and color. These basic characteristics of photographic images provide distinct
"clues" as to the proper classification of a mapping unit. Using collateral data, including input from the
on-site field verification, our photointerpreters will be able to classify and delineate the Land Cover
features throughout the project area.
Photo Science's photointerpreters shall be able to distinguish between and among subtle spectral
signatures. Most of the Land Cover features will be delineated and classified by Photo Science in a
heads-up digital environment monoscopically. If, stereoscopic viewing is required Photo Science will do
so using Socket Set soft copy photog ram metric workstations for on-screen stereo-viewing of 2006 pan-
chromatic ADS40 imagery. Photo Science Photointerpreters will reference all appropriate collateral
data along with input from County staff. This proposed approach follows standard aerial photography
interpretation techniques that have been successfully used on similar inventories of large geographic
areas.
When using the 2006 ADS40 imagery, Photo Science photointerpreters will undoubtedly document
discrepancies between the time of the source photography (2006) was taken and current (2009) ground
truth field conditions. It is anticipated that many of these types of discrepancies between source
imagery and ground truth will be associated with recent urban development on previously non-
developed land. Although the source imagery typically takes priority on these types of situations, Photo
Science photointerpreters will note the discrepancy and consult the County for advice.
If during the photointerpretation and field verification effort Photo Science feels that modifiers to the
classification system may apply, Photo Science shall make those recommendations to the County.
Photo Science shall send samples of photointerpretation work to the County on a regular basis.
Further, the County and Photo Science shall participate in a web conference at any time to view
-4-
progress and to discuss the application of the County's classification system to the land cover features
extracted from the source imagery.
During the photointerpretation phase, all unclassified polygons will be flagged by Photo Science for
inspection in the field. Following a thorough review of all collateral data, the photointerpreters will
select spectral signatures that represent various Land Cover codes that display "problem" or "low
confidence" signatures. Photointerpreters will mark these features on the source photography for
reference for a field site visit.
Photo Science will also provide a narrative within the Final Report discussing probable reasons why a
polygon may have been misclassified such as photo quality, signature variance, decisions rules,
misinterpretations, mapping units or aggregation, etc. Field verification is a necessary component of a
project of this scope and magnitude. Photo Science Photointerpreters must be able to accurately
correlate spectral signatures from source imagery with actual Land Cover codes. Photo Science's
photointerpreters will visit select sites in the field to accurately correlate the Land Cover codes with their
respective unique spectral signatures. This local knowledge-base obtained from the field trip will assist
the photointerpreters with updating both the classification and as needed the delineation of Land Cover
data with a high degree of confidence not otherwise possible. Hard copy plots of imagery annotated
with line work and Land Cover codes will be prepared for the photointerpreter to use in the field.
A large sample site of the Land Cover codes updated will be visited in the field including all polygons
flagged during the PI process. Additionally, Photo Science photointerpreters will visit a representative
number of all other Land Cover codes. During the field preparation, the Photo Science will develop a
plan that allows for the maximum number of codes to be visited.
Photo Science maintains that the photointerpreters assigned to this project are the ones that must
participate in the field work. The field work effort will not be delegated to anyone not directly involved in
the photointerpretation process. Photo Science believes that the knowledge gained from the field is
critical to insuring a high degree of classification accuracy.
Photo Science shall provide field verification as a control measure for photointerpretation, classification
of Land Cover types, and project documentation. Field verification will include visual assessment of
selected Land Cover type. The photointerpreter will also collect a GPS point for each field site visited.
A digital photo will be taken of each site at ground level and incorporated into the field data sheet and
- 5 -
the PI key. When photointerpreters return from the field they will incorporate all ground truth data
collected and update the photointerpretation as needed.
The Photo Science will utilize in-process, draft, and final review processes to assure a complete and
accurate map product are compiled. Emphasis will be placed on creating effective mechanisms that
will assure quality results in interpreted data content and supporting annotations. QC routines will be
woven into the PI production. All work compiled, including all classification codes, will be reviewed
upon completion of each image title before the Photointerpretation begins working on the next image
title. The Project Manager as well as other Photo Science Photointerpreters will conduct "peer reviews"
of each completed image title. To promote consistency and accuracy, the photointerpreter who did the
original work will correct any and all edit calls associated with their own work.
The emphasis of Photo Science's PI QC process will be to identify any critical defects, which could
degrade the FLUCCS integrity of the LCLU map. These defects may include:
. I mproper selection of collateral data.
. Incorrect feature interpretation and coding.
. No feature consistency across project area.
. Features not labeled clearly or completely.
. I ncorrect polygon annotations.
. Missing polygons.
. No adherence to minimum acreage size requirement.
. Improper edgematch to adjoining maps.
Photo Science's PI QA process will continually incorporate measures to assure the highest standard of
accuracy. In order to provide unbiased and unencumbered quality assurance, Photo Science will
organize all quality assurance functions to be separate from, and to operate independently of, the
production team. This includes checking each delineated image title, inspecting it to assure that all
land cover features are properly delineated and classified and are in compliance with a minimum
mapping imit.
- 6-
Regular internal coordination meetings will be held between the Project Manager and the
ph otoi nterpreters , the QA/QC Manager to discuss progress, findings, and any problems or anomalies
encountered. Items typically discussed include characteristics of the imagery, collateral data, decision
rules, and specific project objectives. The County is encouraged to participate in these meetings via
conference call or web meeting or site visit.
All Land Cover features compiled by Photo Science will be meet the following standards for logical
consistency:
· Polygon line work will not be generalized along sinuous features. Line work will properly
characterize the shapes of boundaries appropriate to the resolution of the source imagery.
· Minimum dimensions of mapped features will conform the Minimum Mapping Unit.
· In the unlikely case that the source imagery does not edge match, Photo Science will notify the
County for resolution
· Identically coded polygons will not be adjacent to each other within a feature class
· All features will exist wholly within the registration coverage title bounding arcs
· There will be no duplicate features
· Topology rules will be validated and corrected prior to delivery of each and any deliverable
· All tolerances will be consistent across all deliverables.
Photo Science will assure positional accuracy by checking that all coordinates are referenced,
maintained and delivered in the State Plane Coordinate System, Florida East Zone, units survey feet,
North American Datum (NAD) 1983/99 (NAD83/99). Projection information will be present in the
metadata file and accessible through ArcCatalog
Photo Science proposes that the thematic accuracy of the land cover dataset delivered to the County
will have an overall minimum thematic classification accuracy of 90%. This overall classification
accuracy will be calculated as a weighted average of all classes for each deliverable weighted by total
area covered by each class. Photo Science proposes to confirm the thematic accuracy of the lands
cover data set with a thematic accuracy assessment.
The attribute table will contain their contract specified fields in the correct order and defined correctly.
There will be no superfluous attributes or attribute fields in the final deliverable. All fields will be coded
correctly and completely. There will be a value in every polygon for every attribute.
- 7-
P .1. Decision Notes and General Notes will be filled out whenever deemed useful or appropriate by
Photo Science's Photointerpreters and will be standardized in such a way that allows identical
comments/issues to be identified. There will be a value in every polygon. Where no value applies the
default will be "N.lA".
Attribute Codes: At a minimum, the following attributes will be associated with each digitized polygon:
. LCCODE This attribute will be populated with a land cover value based on the County
classification system. This field will be present in the final deliverable.
. Modifier This attribute will be used to add additional detail to the classification, such as temporary
conditions, minor features or management factors, that may be of particular interest to the County
but do not warrant adding new classes to the Classification system. This will provide the County an
opportunity to customize the classification without effecting overall consistency. This field will be
present in the final deliverable.
. Photointerpretation Code The photointerpreter responsible for the Land Cover determinations will
be identified by this code value. This field will be present in the final deliverable.
. PI Decision Notes This attribute will use standardized codes to record issues regarding the
interpretation decision made for an individual polygon. This field will not be present in the final
deliverable.
. General Notes Decisions that record uncertainties or level of confidence will be recorded in this
note field. Also, general rules for anecdotal data unrelated to the PI decision will be referenced
here. This field will not be present in the final deliverable.
. Field Check. Features identified for verification in the field are identified with this field.
The Photo Science will develop QC protocols specific to this project that will ensure that all deliverables
meet or exceed all accuracy standards established for this project under Monroe County's RFP. Photo
Science's QC and editing process will continually incorporate measures to assure the highest standard
of accuracy. Photo Science shall hold periodic coordination meetings between project management,
photointerpreters, and related project support personnel to discuss progress, findings, and any
problems or anomalies encountered. The County is encouraged to participate in any of these meetings
via conference call, web meeting or site visit.
- 8 -
QC routines, developed by Photo Science will be used to review the digital data.
In summary, Photo Science's automated and non-automated QC/QA routines will insure that the
following standards for logical consistency apply:
· Polygon topology is present and verified using the following rules : do not overlap and do not
have gaps
. Correct application of the MMU
. No duplication of features
. No sliver polygons will exist
. No label errors will exist
. No contiguous polygons
Additionally, Photo Science's QA/QC process will insure all standards for positional accuracy apply to
this mapping effort. This includes insuring that all coordinates are referenced to the State Plane
Coordinate System, Florida East Zone, units survey feet, North American Datum (NAD) 1983-90
(HPGN). All projection information will be present in the metadata file and be accessible through
ArcCatalog.
Photo Science's process will insure that the attribute table contains their ArcGIS coverage default items
and contract specified items in the correct order and defined correctly. There will be no superfluous
attribute tables or attribute items in the final deliverable. All items will be coded correctly and
completely. There will be a value in every polygon for every attribute. Where no value applies, we will
use 9999. All .pat and .aat table definitions will be consistent across all deliverables.
Photo Science shall produce a Photointerpretation (PI) Key for the County. The PI Key will be
developed in order to document the decisions and mapping conventions applied during the photo
interpretation process. It will describe and illustrate the classification system in detail. The PI Key will
be used to assist the photo interpreters compile the land cover features and help to ensure that the
photo interpretation is consistent throughout the project. It will be designed to provide descriptions of
the visual and spatial distribution characteristics of the classification type used for the project and
documents any special mapping conventions which may be developed. Its purpose is to define a
common set of rules and standards that can be applied by many different interests to arrive at a
consistent interpretation. Additionally, the PI Key will contain the general logic and details behind the
decision rules for producing the Land Cover dataset. These details will be in the form of documentation
that lists the appropriate Land Cover classes.
- 9-
Since the potential set of rules can be complex and endless, the County will be provided with a practical
level of useful details conforming to the methodology and to the specific capabilities and needs of
targeted users. The PI Key also serves to provide insight for future users into the rationale for the
delineations and classifications appearing within the database. The PI Key will be in a digital format
and will include the County's classification system. Users will be able to access the PI Key, point and
click on a selected code to access the Photo interpretation Key file which describes the selected code.
Aerial images will be clipped from the original imagery used for the photo interpretation. These image
clips will be displayed on each key page. In addition, field pictures taken at ground level of each land
cover code representing each classification type will also be included on each key page.
Guidelines for each land cover code specific to this project will be specified in the PI Key. Each PI Key
page will describe a unique land cover classification. The following sections will be included on each
page of the key:
1. Classification Code: Indicates the land cover code as applied during photo interpretation.
2. Land Cover Description: This is the definition of the classification code exactly as it appears within
County documents.
3. Keys to Photo interpretation: These will be descriptions which consist of the typical
characteristics of each land cover code. Features which are associated with the class and which
are visible on the imagery will be described. The apparent signature (colors, tones, textures, etc.)
of the land cover code on the imagery will also be described.
4. Special Mapping Conventions: Describes the photo interpretation or mapping rules established to
address the particular classification code.
5. Metadata: Documentation that describes the methods used to produce the PI Key including
problems encountered, problem resolution, clarification in scope, etc. The metadata compiled will
comply with Federal Geographic Data Committee (FGDC) STD-001-1998 Content Standards for
Digital Metadata (version 2.0).
6. Anecdotal information including problems encountered and remedies deployed.
To add clarification to the document, the approved PI Key may be modified with County approval during
project implementation. It may also be necessary for land cover classes to be modified during mapping
based on project working experience with the Land Cover classification system while maintaining
- 10-
consistency throughout the project area. All such changes will be submitted to the County for approval
before processing. All mapped classes will be appropriately represented in the PI Key.
The PI Key will be thoroughly tested to insure it is comprehensive and user friendly. Following internal
testing of the PI Key, Photo Science will meet with County staff to demonstrate and deliver the PI Key
as well as to demonstrate the working environment dedicated to this project.
To insure the land cover dataset delivered to the County has a minimum classification accuracy of 90-
percent for each Land Cover category at a confidence level of 90-percent, and that the overall accuracy
of each section deliverable will have a minimum classification accuracy of 90-percent at a confidence
interval of 90-percent, Photo Science proposes to conduct a thematic accuracy assessment as part of
the QA procedure PRIOR to final delivery.
Photo Science proposes to use a quantitative method (a statistical approach) described by Congalton
and Mead (1983) to determine thematic accuracy of the final Monroe County Land Cover maps to be
compiled. This method involves comparing the results of two separate and independent classifications
of the same features. The first classification results from the initial 2008-09 Photo Science map
compilation effort that used a combination of photointerpretation and field work techniques. The second
classification results from the classification derived an independent photointerpretation conducted by
HDR combined with direct fi~ld observations as needed. Similarities and/or differences between these
two classifications (Photo Science and HDR) shall be displayed in an error matrix, (also referred to as a
similarity matrix).
The resultant error matrix will be used to measure the overall thematic accuracy of the first
classification results. The following methodology shall be deployed:
Step 1: Photo Science will use GIS tools to select a minimum of
20 polygons from each land cover codes from the classification that Photo
compiled. This equates to over 200 polygons.
Science
Step 2: Photo Science shall drop all attributes associated with each of the
selected, leaving only a polygon 10.
polygons
- 11 -
Step 3: Photo Science subcontractor (HDR) shall conduct an independent classification using
photointerpretation techniques of the selected polygons without referencing Photo Science's
original classification. Signature identification may require field work. HDR classification results
will be compared with Photo Science's classification. The following information shall be
displayed when comparing these two datasets:
· Total number of polygons for each classification,
· Number of polygons which are correctly classified,
· Number of polygons that are incorrectly classified.
Photo Science shall perform a statistical analysis by running the Arc Intersect Command within
ArcMap. This command allows the user to overlay the polygons from the original Photo Science
classification and the second classification conducted by Photo Science's subcontractor (HDR). The
resulting output will have the combined attributes of the features in the two inputs. From the analysis of
the Arc Intersect generated layer, Photo Science shall compare the classifications from the two
sources. The 'Notes' field within the Geodatabase shall be used by Photo Science to document
comments for the sampled polygons as well as to identify where any errors are occurring outside of the
sample polygon datasets.
Photo Science shall then conduct a statistical analysis of the dataset. All generated polygons shall be
combined to represent one batch sample. A statistical analysis shall then be performed solely on the
batch sample containing all the sampled polygons. A similarity matrix (or error matrix) will be produced
as a square array set out in rows and columns expressing the number of polygons assigned to a
particular feature type relative to the independent classification.
Once the error matrix is generated it will be analyzed using a discrete multivariate analysis technique
using a program called KAPPA developed by Congalton et al (1982). The Kappa coefficient equation
adjusts for polygons that may match purely by chance. The overall classification accuracy will then be
calculated as a weighed average of all classes (weighed by total area covered by each class). The
statistics used will be the maximum likelihood estimate from the multinomial distribution and shall be a
measure of the actual agreement minus the chance agreement. The variance of these estimates will
then be used to construct a hypothesis test for significant difference at varying confidence levels to
determine if the two independent classifications are significantly different. The accuracy percentage
- 12 -
shall then be calculated for each mapping code by dividing the total number of matching polygons by
the total number of sample polygons processed.
Finally, Photo Science will provide the County with a Thematic Accuracy Report which compiles the
results of the statistical analysis. Results will be summarized in a concise and organized form. The
report will compare the data quality and discussed similarities and differences, providing conclusions
about consistency and completeness. This report will also include suggestions as to what factors may
have caused any observed differences and recommended possible remedies. Also included in this
report will be a discussion on probable reasons why a polygon may have been misclassified such as
photo quality, signature variance, decisions rules, misinterpretations, minimum mapping unit or
aggregation, etc. The County shall be provided with the error matrix, a statistics review report based on
the comparison of the two datasets and the KAPPA coefficient computation. The County will also be
provided with a summary of systematically mismatched classes on a spreadsheet.
Photo Science shall provide the County with high quality metadata that is compliant with the Federal
Geographic Data Committee (FGDC) standards pursuant to Circular A-16 and Executive Order 12906.
Photo Science will lead and organize all metadata creation and management activities for the Land
Cover database development efforts.
