Aerial imagery for this project was collected in the spring of 2011 to produce orthophotography at a 6-inch resolution. Purpose: The collection of aerial photographyand production of orthophotography was executed to capture the existing ground conditions at a specific point in time for the purpose of GIS analysis. Orthophotography along with DTM data typically provides an accurate base for digitally representing geographic features upon which a GIS is built.

Logical_Consistency_Report: Compliance with the accuracy standard was ensured by the placement of GPS ground control prior to the acquisition of aerial photography. The following checks were performed. 1. The ground control and airborne GPS data stream were validated through a fully analytical bundle aerotriangulation adjustment. The residuals of the adjustment met the required standards for accuracy.2. The DTM data was checked against the project control. The technician visited and confirmed the accuracy of the project mass points during initial compilation. 3. Digital orthophotography was validated through an inspection of edge matching and visual inspection for image quality. Completeness_Report: The following software was used: 1. Digital Orthophoto processing - APS. 2. Aerotriangulation - ISAT 3. DTM data - Z/I Imaging SSK, APS Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The horizontal rootmeansquare error (RMSE) of the airborne GPS control data does note exceed 20cm.

The Ground control used to support the orthophotographic mapping was collected by either paneling of permanent monuments or photographic identification of strategic points. The coordinates were collected via ground survey techniques. Z/I ISAT software was utilized for the aerial triangulation phase, using high accuracy softcopy stereo plotters. A photogrammetric project was created, adding camera data, photo data, ground control point data and exterior orientation data. An interior orientation was performed for the project photos, automatic pass and tie measurements were executed and finalized with manual measurement of surveyed ground control. The final bundle adjustment was executed using Photo Triangulation (PhotoT) software. The 6-inch resolution or 1"=100' map data was segmented into 2500' X 2500' tiles. Utilizing the raw images from DMC camera, client supplied DTM data, and digital aerial triangulation resulted in the creation of 4-band (RGB,CIR) digital orthoimagery. The digital aerial imagery was rectified using the best algorithm, radiometrically balanced to produce digital imagery of nominally consistent tone and contrast and mosaiced to create a seamless orthophotography of the entire project area. The data was tiled and complete tiles were delivered as GeoTIFF with supplementary TFW files.
