1 INTRODUCTION

The purpose of this project is to fulfill the Department of Revenue’s (Department) responsibilities of providing aid and assistance to the County Property Appraisers as specified in section 195.002(1), Florida Statutes, and to at least once every three (3) years furnish such aerial photographs and non-property ownership maps to the property appraisers as necessary to ensure that all real property within the state is listed on the roll. The Department, for its own use and for the County Property Appraiser’s use, is proposing to contract for the acquisition and delivery of digital orthophotography products. The Department intends to acquire ortho-rectified digital image data to support the development and analysis of the tax rolls for all sixty-seven (67) counties in Florida.

Since 1972, Florida Statutes have stipulated cooperation between USGS, FDOT, and the state Water Management Districts to facilitate statewide topographic mapping efforts. Currently the horizontal part of the statewide topographic map is being accomplished through the Florida County Digital Orthophotography Program (FCDOP). The FCDOP is supported by partnerships and agreements between several state, federal, and local agencies. The current FCDOP mapping efforts consist of statewide orthophotography coverage of Florida on a three (3) year cycle, with a maximum ground sample distance (GSD) resolution of 0.5 feet.

2 PURPOSE

This document defines the minimum standards for providing digital orthophotography products for inclusion into the FCDOP. All final data will be considered public record as defined by applicable Florida Statutes.

Any products created from oblique aerial imagery acquired during the Orthophotography project imagery collection are beyond the scope of this document.

All work performed must be in accordance with the Standards of Practice Chapter 5J-17, F.A.C., pursuant to Chapter 472, Florida Statutes.

4.10 Historical Images

To maintain consistency between images collected during different years, historical examples of imagery shall be reviewed. If applicable color balancing should be performed that is consistent with previous FCDOP imagery.

5 ORTHOPHOTO DELIVERABLES

All deliverables will be the property of the Contracting Agency and are considered public record. Written permission from the Agency must be obtained to release data to any party prior to final publication. The Consultant will deliver Ortho-rectified four band imagery consisting 8-bits per band natural color (RGB) and near infrared (N). The Stereoscopic panchromatic images collected will not be delivered unless specifically requested by the Agency. The Consultant shall keep a copy of the original data for a period of five (5) years and must contact the Agency before destroying the data. The Consultant will document all data deliveries with an itemized transmittal letter.

5.1 File Formats and Image Types

Clarity and quality of the imagery is of the highest importance. Imagery will be delivered as uncompressed four band GeoTIFF images with valid projection header information. One GeoTIFF file per 5000 x 5000-foot tile is required.

a) Natural Color Imagery – The natural color, RGB, bands will be color balanced across the entire study area to the greatest extent possible to allow viewing of the image tiles as a visually seamless mosaic. Care should be taken during radiometric processing to avoid loss of detail in shadows and overexposure on bright surfaces such as bare ground and light-colored building roofs.

b) Color Infrared Imagery – The near infrared band will be radiometrically processed in a manner that preserves original image characteristics to the greatest extent practical. Systematic radiometric corrections to reduce sun angle and sensor variations are desired. Corrections for seasonal variations in ground cover are not to be done, however, care should be taken to ensure appropriate coloration of different vegetation types (e.g. deciduous, evergreen, etc.) is evident.

All orthoimages will be delivered according to the project tiling index (ESRI shapefile) provided to the consultant before commencement of work. The Florida Imagery Index may be found at the Department’s website http://floridarevenue.com/dor/property/gis/.

Tiles will be contiguous and non-overlapping and will be suitable for creating a seamless image mosaic that includes no data void cells or gaps. Tile naming convention is as follows:

YYYY__NNNNNN_RGBN.TIF (4Band Imagery, Required)

YYYY__NNNNNN_RGB.TIF (Natural Color Imagery if requested)

Re: FY 2019/20 Digital Orthophotography; Orthophoto Project Area 1 (Baker) – Pricing Revision

Dear Ms. Goodwin:

On behalf of The Sanborn Map Company, Inc. (Sanborn), it is my pleasure to provide you with this letter of interest to the Florida Department of Revenue (FDOR) for the FY 2019/20 Project Area 1, Baker County, under the Florida County Digital Orthophotography Program (FCDOP).

Sanborn, an ISO 9001:2015-certified company focused on quality, is excited about the opportunity to work with the FDOR again. It has been Sanborn’s privilege to provide mapping services to FDOR since 2006 for digital orthoimagery development. Sanborn is thoroughly familiar with FDOR specifications and your mapping needs, and our history of developing digital orthophotography for you offers a good model for guaranteed quality work and our commitment to schedule.

Project Area

The project area to be mapped consists of 723 tiles 5000 by 5000-foot tiles (cells) (approximately 648 square miles) as defined in the Baker_Tiles.shp shapefile, issued by the FDOR.

The draft flight line map with ground control layout is provided in the Appendix, at the end of this letter response.

Time and Budget Requirements

We understand the mission-critical nature of this project, and the need to produce quality orthoimagery on time, on budget, and to your specifications. We are committed to acquire the imagery as soon as given notice to proceed, with completion of aerial imagery prior to January 30, 2020, and completion of all product deliveries no later than June 1, 2020. We have traditionally met or accelerated the previous project schedules.

An overview of the schedule is provided below.

Proximity to Project Location

At this time of year, we strategically move the required acquisition resources to the southern states of Florida, Georgia and South Carolina, to stay within close proximity of the projects scheduled for acquisition during the late fall/early winter. Sanborn owns and operates 10 aircraft and three (3) UltraCam Eagle imagery sensors, which provides assurance that the critical acquisition phase will be completed efficiently and on schedule.

Mr. Gary Eaton, Florida PSM No. LS0006319, will oversee the mapping from our Charlotte, North Carolina, office.

The orthophoto production will also be performed in our Charlotte office with additional resource production support from our Colorado Springs, Colorado, office.

Current and Projected Workload

Sanborn’s earned value management (EVM) environment, in addition to multiple supplementary tracking systems, enables integrated management of the entire project lifecycle. This project management and production tool is used to develop and track all project resources and the schedule throughout the life of the project, from design and proposal development, to implementation, and change management. Project schedules and resource allocations are modeled in the EVM as early as the proposal stage, then developed and maintained over the entire life of the project. For FDOR’s program, as the collection and processing moves through the timeframes, updates to the EVM allow Sanborn to reallocate resources if necessary and to direct additional assets to cover equipment failures, weather problems or changes in the capacity plan as a result of changes in the collection activity.

The graphs below illustrate our EVM resource analyses. The graphs show significant capacity for airborne imagery acquisition, airborne GPS/IMU processing, image processing (pre-rectification), aerotriangulation, compilation/GIS (DEM ingest and update), and imagery (post processing orthorectification). Based upon this analysis, Sanborn has plenty of capacity to take on the proposed scope of work. Our current workload throughout all phases is as follows:

Scope of Work

All surveying and mapping work performed will meet the Standards of Practice Chapter 5J-17, F.A.C., pursuant to Chapter 472, Florida Statutes. Sanborn is committed to meet or exceed all quality and accuracy requirements as detailed in the Request for Proposal (RFP). The proposed project will include the following items and components:

Acquisition of new imagery using a digital aerial camera capable of collecting multispectral imagery in natural color (RGB bands) and near infrared (IR band N), with a resolution of 6-inches.

Collection of ABGPS/IMU-controlled vertical color imagery for this project will be performed by Sanborn with the advanced UltraCam Eagle digital aerial camera system with 3rd generation architecture. The fixed frame design and photogrammetric based engineering provides accuracy that will meet the required FDOR imagery specifications. All images will be obtained under cloud free conditions and will be free of obscuring haze, smoke or other atmospheric conditions. All images must be collected with a sun angle no less than 30 degrees. Imagery will be acquired at a density in the “high-rise” urban areas such that all road networks are clearly visible and that buildings show no signs of excessive tilt or lean.

Acquisition of data during the specified flight season, from October 1, 2019, through March 15, 2020. Sanborn is committed to acquire the imagery prior to January 30, 2020, weather permitting

Establishment of new photo control points or recovery of a network of ground control as needed to support the Orthophoto mapping. Twenty (20) ground control points will be surveyed and twenty-five (25) checkpoints evenly distributed throughout the project area, for a total of forty-five (45) survey points.

Sanborn will utilize existing ground control on this project to the fullest extent possible, and augment it with new, photo-identifiable or targeted ground control points where needed. Using the ground control survey information, camera calibration information and Airborne GPS/Inertial Measurement Unit (AGPS/IMU) data acquired during the aerial flight, a Fully Analytical Aerial Triangulation (FAAT) solution will be completed, establishing the accuracy standards set by FDOR for updating or generating a new terrain model as needed, and creation of the orthoimagery

Unless otherwise approved, all Airborne GNSS/INS trajectory corrections will be directly referenced to the Florida Permanent Reference Network (FPRN).

Update of the existing lidar DEM, or development of a new DEM using stereo-compilation techniques.

Sanborn will ensure that the DEM used for the orthorectification will be up-to-date and accurate in order to support the 6-inch (1”=100’) resolution accuracy specification

Production of 6-inch Orthorectified image tiles, with four bands, consisting of 8-bits per band natural color (RGB) and near infrared (N)

Delivery of original source imagery as uncompressed 4-band TIFF images (RGBN) at the native bit-depth of the Eagle sensor

Development and delivery of a Seamline Feature Class Provision of an optional, no-cost web-based quality control application for FDOR. Data is served from a central data server at Sanborn to the customer-side computer and uses a mapping interface from within a standard web browser, for FDOR to review the data imagery.

Edit flags are stored in a centralized location where they are immediately available for review by others in the organization. Users are able to view available data and add digital issue points to areas which may have perceived problems or errors, which are submitted directly to a secure centralized database where they are immediately available for others to review.

Benefits of the online QC process include:

Helps reduce the time needed for review as data can be corrected incrementally with edit calls, often speeding the review schedule Provides ease and documentation for data quality review needed for monitoring and compliance Facilitates coordination between many data reviewers

Appendix

The draft flight map and ground control design is provided below. Using the draft flight plan, Sanborn calculates

1.4 missions (full flying days) are required with our Eagle sensor to complete the imagery acquisition. Even considering an approximate weather of 4.5, we are confident we can acquire the imagery in the timeframe required.

All existing ground control points are illustrated on the map below. Sanborn will utilize existing ground control on this project to the fullest extent possible, and augment it with new, ground control points where needed. The final ground control dataset will contain 20 ground control points and 25 checkpoints for a total of 45 ground control points.
