Report: 1. Deliverables the contractor shall provide to the IDL include: Aircraft trajectories, las format all-return point files, ground point list, intensity image, and formal metadata. The report shall be a digital text report that describes survey methods; results; Contractor’s accuracy assessments, including internal reproducibility and absolute accuracy; file formats; file naming schemes; tiling schemes. 2. Aircraft trajectories: (SBET files) shall be ASCII point files or ESRI shapefiles, with aircraft position (easting, northing, elevation) and attitude (heading, pitch, roll) and GPS time recorded at regular intervals of 1 second or less. May include additional attributes, such as temperature and humidity or other relative information the contractor deems appropriate. 3. All-return point cloud: All-return point cloud shall be .las 1.4-R15 format files listing all valid returns; all fields populated. For each return: GPS week and GPS second OR Posix time, easting, northing, elevation, intensity, return #, return classification. May include additional attributes. No duplicate entries. Time shall be reported to the nearest microsecond or better. Easting, northing, and elevation shall be reported to the nearest 0.01 meter. Classification of returns shall be as complete as is feasible and without avoidable return misclassification. 1/100th USGS 7.5-minute quadrangle (0.75 minute by 0.75 minute) tiles. All point cloud data must have erroneous points removed from the dataset...
