The period of aerial collection was 14 DEC 2004 to 15 DEC 2004 with a reflight of several lines conducted on 1 FEB 2006. During the time of image acquisition two dual frequency GPS receivers were utilized. One receiver was operated on board the aircraft with the dual frequency antenna located directly over the camera. The second receiver was used as a base station.These receivers were in constant operation during the imagery mission and GPS phase data was collected at an epoch rate of 1 second. The airborne GPS data and IMU were used in combination with ground surveyed points to control the imagery. The imagery fully encompasses the project boundary. The DTM deliverable for this project was manually compiled using stereo pairs generated from the orthophoto flight. The DEM masspoint grid used to rectify the orthophotography was derived from the compiled DTM. All data produced for this project was referenced horizontally to NAD83, and vertically to Mean Sea Level(MSL), NAVD 88 in UTM meters.

The ground control for this project consisted of 25 vertical/horizontal photo-identifiable points.The ground control is referenced horizontally to NAD83, and vertically to Mean Sea Level(MSL), NAVD 88 in UTM meters. Airborne GPS data was collected during the acquisition mission for each flight line. The control points were measured by technicians using ISTAR 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. Horizontal Positional Accuracy The digital mapping products fully comply with ASPRS Class 1 standards for production of orthophotos at a scale of 1/2400 with an orthophoto ground pixel resolution of 50 centimeters . Vertical Positional Accuracy The DEM and DTM fully comply with the contracted specification of 50-centimeters RMSE in the vertical. Completeness Measure Cloud Cover: 0 Completeness Report 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. The following software is used for validation of the 1. Aerotriangulation - ISTAR 2. DEM data - photogrammetrically compiled 3. Digital Orthophotography - ISTAR The following software was used for the validation. 1. Bentley - Microstation 2. ISTAR 3. ZI OrthoPro 4. ESRI - ArcInfo 5. EarthData Proprietary software Conceptual Consistency Compliance with the accuracy standard was ensured by the collection of photo identifiable GPS ground control before and 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. The airborne GPS data were processed and integrated with the IMU. The results were imported into the ISTAR system for use in the aerotriangulation. The ADS40 imagery was downloaded onto the EarthData server and brought over to the UNIX based ISTAR system. The ground control was used in conjunction with the processed ABGPS results for the aerotriangulation. The properly formatted ISTAR results were used for subsequent processing. 2005-06-16T00:00:00 This process describes the import and QC of the photogrammetrically-derived DEM surface from stereo pairs for use in the ISTAR processing system. 1. Using the DEM data set, the technician performed a visual inspection of the data to verify that the flight lines met correctly. The technician also verified that there were no voids, and that the data covered the project limits. The technician then selected a series of areas from the dataset and inspected them where adjacent flight lines met. A process, which utilizes 3-D Analyst and EarthData's proprietary software was run to detect and color code the differences in elevation values and profiles. The technician reviewed this information and located the areas that contained systematic errors or distortions that were introduced by the auto correlation. 2. Systematic distortions highlighted in step 1 were removed and the data were re-inspected. Corrections and adjustments can involve the application of angular deflection or compensation for curvature of the ground surface that can be introduced by crossing from one type of land cover to another. 3.The data were checked against the control network to ensure that vertical requirements were maintained. 2005-06-22T00:00:00 The digital orthophotography is comprised 50 centimeter pixel Ground Orthos. Once the DEM data was integrated into the ISTAR 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 ISTAR 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. 2005-06-30T00:00:00 Source Contribution: The aerial imagery acquisition for the Florida Greenway Corridor was flown to support the creation of digital orthophotography with a 50 centimeter pixel.

Digital aerial imagery (Leica ADS-40) observations were made for the project.Terrasurv utilized the Global Positioning System (GPS) to establish the control network. 1) The photo control stations were established post flight; therefore all new stations are photo-identifiable points. No permanent stations were set. There were a total of 25 new photo identities established. In addition, there were 3 temporary base points and the airborne GPS (ABGPS) base station used by the flight crew. 2) 17 additional photo identities were obtained in December of 2005 to support the reflight of several flight lines. | Source Geospatial Form: model | Type of Source Media: paper 2400 Florida Greenway Digital Orthophoto Ground Control 2005-02-25 publication Terrasurv Inc. 2006-03-13 otherRestrictions otherRestrictions Access Constraints: None | Use Constraints: None
