The orthoimagery was produced by The Sanborn Map Co., Inc. and provided to the City of Lubbock, TX in TIFF, MrSID and HMR formats. The orthoimagery is tiled to 1/4 square mile tiles named based on naming convention provided by the City of Lubbock that indicates the City's basemap grid number and geographic quadrant of the grid (NW, NE, SW, SE). Purpose: The color digital orthorectified aerial imagery(orthophotography) is provided to the City of Lubbock, TX and the Lubbock Metropolitan Planning Organization serves as a base map to be used for multiple purposes such as planning, map production, and photo interpretation.

Logical_Consistency_Report: Since the ortho images are raster products, the logical consistency is based on how well the images fit between image tiles and between individual photo frames use to produce the ortho mosaics. The images match within four pixels of each other throughout the project area. Completeness_Report: The ortho image tiles are checked for missing pixels, gaps, overlaps and other anomalies generally associated with digital orthophoto products. The ortho tiles are checked and any discrepancies are resolved through the use of proprietary and industry editing tools. Once the images are copied to the deliverable media they are further checked for naming, image completeness, and image ability to be opened in GeoMedia.

Predefined points within the project area are targeted and photo-identifiable locations are measured. These points along with their precise coordinates are used in the aerial triangulation process and to check the horizontal accuracy of the resulting orthophotos.

The aircraft were equipped with inertial measurement units (IMU) and aerial global positioning systems (GPS) to precisely measure the orientation and location of each image. Imagery and GPS/IMU data is downloaded from disc on the plane to disc on the ground. GPS/IMU mission data is processed together with simultaneously collected ground-based GPS base station data in forward and reverse directions. This precisely determines the aerial camera's position and orientation in the terrain (project) coordinate system and allows for correct orientation of the imagery. The 0.25 foot imagery was acquired at approximately 2,500 feet above terrain. Imagery was acquired with 60% endlap and 30% sidelap between photos to provide full stereoscopic coverage.

The LiDAR data is processed to remove elevated points to create a digital elevation model (DEM) sufficient to support production of orthoimagery. Process_Step: Process_Description: The aerial triangulation process uses the processed GPS/IMU data and correctly oriented imagery to compute the bundle adjustment.

The digital elevation model (DEM) data for the 3-inch pixel resolution orthoimagery was produced from 0.7 meter nominal point spacing (NPS) LiDAR data processed to a bare earth surface. The data is translated to the orthoimagery production environment, and images are rectified to the surface.

Once rectified, the orthoimagery is colorbalanced to the acceptable parameters established by the City of Lubbock. Seam lines are generated where images overlap, eliminating the outer portion of each image to reduce distortion and radial displacement of features in the orthoimagery. Seams are generated at the surface to avoid splitting significant structures such as building features. Orthoimagery undergoes manual quality control to check for issues as outlined in the Digital Orthoimagery Acceptance Criteria document. Issues such as warps, smears, misalignments, etc. are corrected using proprietary tools and Adobe PhotoShop. Upon completion of the QC process, the orthos are provided to the City for review. Any unacceptable orthoimagery is corrected and the final orthoimagery is then delivered to the City.
