EarthData International 20070716 remote-sensing image GeoTIFF 1 Frederick, MD 21704 Fugro EarthData, Inc. http://www1.usgs.gov/vip/deso/desoortho.zip doi:10.5066/F7PG1PP8 EarthData International collected ADS-40/ISTAR-derived orthophotography over Hillsborough, Pinellas, Manatee and Sarasota Counties Florida with a 1 foot pixel resolution. The period of collection was between 9 January and 20 January 2007 for the base area with the agricultural area bring flown between 17 February and 19 February 2007. The collection was performed EarthData Aviation, using a Leica ADS-40 camera system, including an inertial measuring unit (IMU) and a dual frequency GPS receiver. This project required eight lifts of flight lines to be collected, for a total of 80 flight lines. The orthophotos were rectified using the existing lidar DEM from Pinellas County and a collected DEM from Hillsborough County and was processed using ISTAR. Ground survey services in support of the project were provided by a Florida-registered professional land surveyor under the employment of Terrasurv Inc. of PA. The GeoTIFF format was compressed to MrSid format for distribution or is stored in ArcSDE for District use. This data was collected and derived for the Counties of Hillsborough, Pinellas, Manatee and Sarasota through a joint teaming effort with the Southwest Florida Water Management District (SWFWMD). The following products were produced for this project and Hillsborough, Manatee and Sarasota Counties (all deliverables in Florida State Plane, feet, West Zone NAD83/99) (1) Natural Color 24-bit tiles in GeoTIFF format (2) Color Infrared 24-bit tiles in GeoTIFF format. Pinellas County (all deliverables in Florida State Plane, feet, West Zone NAD83/99 AND in NAD27) (1) Natural Color 24-bit tiles in GeoTIFF format (2) Color Infrared 24-bit tiles in GeoTIFF format. 20070109 20070219 ground condition Complete Annually De Soto National Memorial and environs -82.651626 -82.636039 27.537246 27.509668 none Digital Imagery Orthos Orthoimage Digital Orthophotography Aerial Photography ADS40 National Park Service Theme Category Thesaurus Digital Orthophoto ISO 19115 Topic Category imageryBaseMapsEarthCover Geographic Names Information System Florida Hillsborough County Pinellas County Manatee County Sarasota County National Park System Unit Name Thesaurus De Soto National Memorial National Park System Unit Code Thesaurus DESO None Use of these data requires a general understanding of GIS and spatial data.

The ground control for this project consisted of 36 vertical/horizontal photo-identifiable points and processed to FL State Plane West NAD83/1999 , and vertically to Mean Sea Level(MSL), NAVD 88 in U.S. Survey Feet. Airborne GPS data was collected during the acquisition mission for each flight line. An additional control point was set for a basestation that was recorded during imagery acquistion for processing the airborne GPS. The control points were measured by technicians using Orima software. The final bundle adjustment of this block was solved using airborne GPS. During GPS data collection, the Positional Dilution of Precision (PDOP) was monitored and held at or below 3.5 when possible. Imagery was mosaiced to provide seamless coverage. Images were then radiometrically corrected for tone balance and geometry quality control along tile edges for terrain and linear features. EarthData QC Compliance with the accuracy standard was ensured by the collection of photo identifiable GPS ground control after the acquisition of aerial imagery. The following checks were performed. 1. The ground control and airborne GPS data stream were validated through a fully analytical bundle aerotriangulation adjustment. 2. The DEM data was checked against the project control. The technician visited and confirmed the accuracy of the points during initial processing. 3. Digital orthophotography was validated through an inspection of edge matching and visual inspection for image quality. 4. Planimetry was validated through an inspection of edge matching and visual inspection for data quality. 5. A final quality control check utilizing 20 QC ground survey points was conducted, ensuring that minimum accuracy requirements were met. SWFWMD QC The imagery data layer stored in the District's enterprise database is opened in ArcMap. The District's LiDAR project grid is also added. The imagery is scanned at 1:6,000 looking at each LiDAR grid cell individually. If a problem is found, then a point shapefile is created and a point in the location of the problem is added. Comments are added to the shapefile in an attribute field about the problem and a bitmap is created displaying the area with the problem. Each bitmap includes: comments added to the shapefile, grid cell number, date, initials of the QC staff, and whether the image is drawn to the full extent. The overall color balance between cutlines over land, offsets over 8 feet, missing data, anomalies, and overall color balance. The following methods are used to assure imagery accuracy. 1. Use of IMU and ground control network utilizing GPS techniques. 2. Use of airborne GPS in conjunction with the acquisition of imagery. 3. Measurement of quality control ground survey points within the finished product. The following software is used for validation of the: 1. Aerotriangulation - Orima 2. Check of DEM data 3. Digital Orthophotography - Orima The following software was used for the validation. 1. Bentley - Microstation 2. ISTAR 3. ZI OrthoPro 4. ESRI - ArcInfo 5.

Terrasurv, Inc. 20060228 model 2400 paper 20070508 Publication Date Ground Control Terrasurv, Inc. was contracted by EarthData to acquire 2 temporary base station points, 16 vertical/horizontal photo-identifiable points, and 20 quality control control points before, during and after the acquisition of aerial imagery. The ground survey tasks we conducted by Kevin J. Chappell, Florida PSM License No. LS5818. The Global Positioning System (GPS) was used to establish the control network. The horizontal datum was the North American Datum of 1983, 1999 adjustment (NAD 1983 1999). The vertical datum was the North American Vertical Datum of 1988 (NAVD 1988). The project had a total of 49 ground control points with the balance of points that were used were from projects previously done for South West Florida Water Management District. Hillsborough County 20041205 remote-sensing image 2400 Mobile Hard Drive 20070515 Publication Date ISTAR DEM The elevation data used for the rectification of the orthophotos in Hillsborough, Pinellas, Maantee and Sarasota Counties was created by using the aerial imagery and the Aerial Triangulated solution. The airborne GPS data were processed and integrated with the IMU. The results were imported into the processing system for use in the aerotriangulation. The ADS40 imagery was downloaded onto a production server. The ground control was used in conjunction with the processed ABGPS results for the aerotriangulation. The properly formatted processing results were used for subsequent processing. Aerotriangulation 20070529 AT EarthData International Frank Sokoloski Project Manager mailing and physical address

Once the DEM data was integrated into the processing system the initial radiometric adjustments were performed on the imagery for each flight line attempting to reach the best possible histogram. The rectification process was run using the processed DEM surface and the radiometrically balanced imagery on each flight line. A second set of radiometric adjustments were made and mosaic lines were placed. QA/QC was performed looking for smears and other indications of problems within the digital orthophoto creation process. The final imagery data set is removed from the processing environment in a process called "packaging" where the individual tiles are created. The created tiles are reviewed again for anomalies and interactive radiometric adjustment applied where needed. The final product was GeoTIFF format digital orthos.

Statistics was built using the software TOAD on all raster tables in SDE. For the District's GIS Data Distribution site, MrSid mosaics are created using the GeoExpress software by LizardTech. They are compressed at a ratio of 20:1 from GeoTiff files. These mosaics then have projection files (.aux) created for viewing with ArcGIS.
