Capture Conditions Generally leaf-off conditions and no haze, clouds, fog, dust, smoke, air pollution, snow, or other ground obscuring conditions shall be present. Capture shall occur within two (2) hours before and two hours after maximum sun angle, and when the sun angle is not less than 35 degrees above the horizon. Images shall not contain objectionable shadows caused by relief or low solar altitude. The downtown area of the City and other tall building locations shown in the following Figure shall be scheduled to occur as late as possible in the leaf-off acquisition window and at high noon or at the time with the best solar angle possible to minimize shadow effects of tall buildings. The true ortho area shall be acquired with 80% forward lap and 80% side lap. 3.4. Flight Design The average 6,008-foot flying height above mean terrain is designed to capture aerial imagery at a pixel ground resolution slightly less than 0.25 feet square. This flight height is appropriate for achieving the required final pixel resolution of 0.25 feet. It is also designed for developing DEM inputs with vertical accuracy appropriate for orthorectification in areas where new surface modeling may be required. The flight mission shall be designed such that forward lap is 60% and sidelap 30% in areas of gentle terrain. Crab shall not be in excess of three (3) degrees; and tilt of the camera from verticality at the instant of exposure shall not exceed three (3) degrees. The flight mission schedule must include sufficient time for captured data to be inspected and for any necessary reflights to be completed within the capture window and prior to the project delivery date. Reflights shall be centered on the plotted flight lines and must be taken with the same camera system. The Contractor at no additional fee must correct aerial imagery that does not meet defined specifications. 3.5. Horizontal Positional Accuracy Horizontal accuracy testing should follow the ASPRS Positional Accuracy Standards of Digital Geospatial Data, Edition 2, Version 1.0 — August 23, 2023. Accuracy tests will meet or exceed requirements for "Standard Mapping and GIS work" which is a 2-pixel RMSEx and RMSEy accuracy class. For the 3-in imagery this will be 6 inches. Accuracy testing parameters shall be determined by the Contractor in consultation and with concurrence of the City's Project Manager. Complete accuracy testing results of all well-defined points shall be provided in the metadata to the City at the time of data delivery. The City may choose to use a third party to validate the accuracy of the dataset. Figure 2- True Orthophotography FlightArea 3.6. Aerial Triangulation (AT) Aerial triangulation will be performed using industry-standard procedures and software packages to support the horizontal accuracy requirements of the orthophotography as detailed in the proposal. 3.7. Image Quality Orthophotography shall be clear and sharp in detail with no noticeable blemishes and be radiometrically and geometrically corrected to enable adjacent files to be displayed simultaneously without obvious differences in tone, contrast, or position of ground features between single images, across the block, or across the database. The most nadir part of every image will be used in mosaicking. Seam lines will be created to ensure that joins do not cut hard detail and will not cross through above ground structures. Visible seams within a tile or between tiles, which exhibit a noticeable "edge" or "displacement" effect, will be grounds for rejection of tiled or mosaiced data. The imagery shall not contain defects such as out-of-focus imagery, blurs, whorls, color blemishes, or any other kind of digital blemish or data corruption. Feature warp or misalignment, smearing, double image, or image stretching indicating bad elevation data shall not be present and will be grounds for rejection of tiled or mosaiced data. Distortion resulting from elevated surfaces such as bridges and interchanges or other abrupt changes in elevation shall be corrected or removed. Occlusion and smearing in areas of extremely high relief shall be fixed or minimized to the extent possible using overlapping orthophotos. Color and contrast adjustments are allowed in post process production if information is not lost in the shadows or highlights as a result of the process. Image quality will be approved by the City at the pilot project phase. 3.8. Pilot Project The contractor will conduct a pilot project before executing final deliverable production. Pilot project deliverables will be provided to the City for assessment and input on general project quality, color, aesthetics, and to test out final deliverable formats. The pilot project area will be determined in consultation with the City and may be discontinuous and shall represent urban, rural, downtown, and semi-urban areas. It is anticipated the pilot project area will be approximately 10 to 15 square miles. 3.9. Image Tiling See Section 2.2.1 of this Scope. Tile grids identical to previous projects will be supplied by the City. Orthophotography files will be named according to the locally used tile identification. 3.10. Geodatabase Raster Mosaic An ESRI specification Geodatabase Raster Mosaic will be developed at three-inch (3") GSD resolution of the entire project area from the uncompressed final project orthophotography tiles. The raster mosaic shall have image pyramids and statistics produced and delivered within raster mosaic geodatabase. This mosaic will serve as the foundation for generating and ESRI image service compliant tile cache. The cache will use existing WMTS level, scale, and spatial reference system specifications defined in the City's existing and current image service. 3.11. Input Orthorectification DEM/DTM The City will provide a LiDAR derived surface for use in the orthorectification process. In areas where surface may need to be updated, a DTM/DEM shall be developed at a density level necessary to accurately represent the shape of the ground and support the orthophoto production and accuracy specifications as outlined in this Scope. Terrain/elevation data used in the development of the DTM/DEM shall be captured by photogrammetric techniques. Existing LiDAR data shall be reviewed by the Contractor to determine if significant terrain altering activity has occurred since the LiDAR data was acquired. Contractor shall update the DTM in that area. 3.12. True Orthophotography True orthophotography shall be developed in areas in the vicinity of downtown and as indicated in Figure 2. Selected buildings greater than five (5) stories in this area shall be modeled to allow for the correction of building lean and occlusions. Planimetrically accurate and topologically sound feature data shall be collected to provide for detailed digital surface modeling of extruded building walls and relevant building roof superstructure detail. Additional aerial photography shall be collected with 80% overlap to facilitate the correction of occlusions in identified true orthophotography areas. 3.13. ArcG15 Image Service Cache Image Service Cache generated from ESRI ArcGIS image service as compact cache storage format. The cache schema will be defined by the Cit�/s existing caches used in 2021. 3.14. Building Footprint Update The City will provide the current building footprint coverage. This coverage will be updated by the Contractor to reflect the building footprint structures that have been added, modified, and deleted as observed in the newly produced aerial orthophotography. This will be accomplished with change detection techniques employed on the current footprint coverage compared to the new aerial photography. The contractor will provide a delivery of the updated building footprints in a single geodatabase. These updated building footprints will have consistently populated attribute fields as provided in the City schema. Updated building geometry will be limited to buildings exhibiting 120 square feet or greater change. 4. Project Delivery A single set of deliverables shall be required. The City of Lubbock will use the final deliverables with ESRI software packages, and all data requested must be useable in this suite of software with no further manipulation. Product deliverables are defined in the Delivery Manifest. 4.1. Media Digital data deliverables shall be provided on industry standard removable hard drives with high speed transfer rates including support for the latest USB specification connections. 4.2. Metadata Complete, Federal Geographic Data Committee (FGDC) compliant (reference FGDC-STD-001-1998) metadata shall be provided for each component of the project, including digital orthophotography, building footprint collection, and DEM/DTM data. All metadata shall be delivered at the same time and on the same media as the dataset delivery. Each delivered metadata file will include the City of Lubbock disclosure statement. 4.3.

Tile grids identical to previous projects will be supplied by the City. Orthophotography files will be named according to the locally used tile identification. 3.10. Geodatabase Raster Mosaic An ESRI specification Geodatabase Raster Mosaic will be developed at three-inch (3") GSD resolution of the entire project area from the uncompressed final project orthophotography tiles. The raster mosaic shall have image pyramids and statistics produced and delivered within raster mosaic geodatabase. This mosaic will serve as the foundation for generating and ESRI image service compliant tile cache. The cache will use existing WMTS level, scale, and spatial reference system specifications defined in the City's existing and current image service. 3.11. Input Orthorectification DEM/DTM The City will provide a LiDAR derived surface for use in the orthorectification process. In areas where surface may need to be updated, a DTM/DEM shall be developed at a density level necessary to accurately represent the shape of the ground and support the orthophoto production and accuracy specifications as outlined in this Scope. Terrain/elevation data used in the development of the DTM/DEM shall be captured by photogrammetric techniques. Existing LiDAR data shall be reviewed by the Contractor to determine if significant terrain altering activity has occurred since the LiDAR data was acquired. Contractor shall update the DTM in that area. 3.12. True Orthophotography True orthophotography shall be developed in areas in the vicinity of downtown and as indicated in Figure 2. Selected buildings greater than five (S) stories in this area shall be modeled to allow for the correction of building lean and occlusions. Planimetrically accurate and topologically sound feature data shall be collected to provide for detailed digital surface modeling of extruded building walls and relevant building roof superstructure detail. Additional aerial photography shall be collected with 80% overlap to facilitate the correction of occlusions in identified true orthophotography areas. 3.13. ArcGIS Image Service Cache Image Service Cache generated from ESRI ArcGIS image service as compact cache storage format. The cache schema will be defined by the Cit�/s existing caches used in 2021. 3.14. Building Footprint Update The City will provide the current building footprint coverage. This coverage will be updated by the Contractor to reflect the building footprint structures that have been added, modified, and deleted as observed in the newly produced aerial orthophotography. This will be accomplished with change detection techniques employed on the current footprint coverage compared to the new aerial photography. The contractor will provide a delivery of the updated building footprints in a single geodatabase. These updated building footprints will have consistently populated attribute fields as provided in the City schema. Updated building geometry will be limited to buildings exhibiting 120 square feet or greater change. 4. Project Delivery A single set of deliverables shall be required. The City of Lubbock will use the final deliverables with ESRI software packages, and all data requested must be useable in this suite of software with no further manipulation. Product deliverables are defined in the Delivery Manifest. 4.1. Media Digital data deliverables shall be provided on industry standard removable hard drives with high speed transfer rates including support for the latest U56 specification connections. 4.2. Metadata Complete, Federal Geographic Data Committee (FGDC) compliant (reference FGDC-STD-001-1998) metadata shall be provided for each component of the project, including digital orthophotography, building footprint collection, and DEM/DTM data. All metadata shall be delivered at the same time and on the same media as the dataset delivery. Each delivered metadata file will include the City of Lubbock disclosure statement. 4.3. Deliverable Manifest This 2024 deliverable dataset manifest states the full transfer of deliverable data products on an external hard drive to be made at the project conclusion. The following tables summarize deliverable content provided for the project tasks selected Area of Interest.
