Produced from 18 color infrared photos taken April 13, 2003. Orthorectification accomplished with Imagine Orthobase v8.6 software. RMSE is 1.453 meters meeting class 1 NMAS. Purpose: The dataset was developed for use by Friendship Hill National Historic Site as a GIS component and for digital monoplotting and mapping.

Horizontal accuracy was assessed on the basis of 34 field survey points distributed throughout the image. The actual field coordinates for these points were recorded with a Trimble ProXRS GPS unit with real-time differential correction with a minimum of 120 (180 unless poor field conitions) fixes per point. The field coordinates were then post-processed using differential correction. The field coordinates were then compared to the image mosaic coordinates for these points, determined in ESRI ArcView 3.3 software.

The photos were scanned at 1200 dpi and imported into Imagine. A DEM was downloaded from the seamless dataset website (seamless.usgs.gov). The 30 meter DEM was resampled to 10 meter resolution in Imagine. The images were orthorectified using ERDAS Imagine Orthobase software. Airborne GPS and IMU data were used in the aerial triangulation procedure. Aerial triangulation produced a single RMSE of less than 1 meter for the entire block of photos. The orthorectified images were then mosaiced within Er Mapper to form one seamless basemap image for Friendship Hill National Historic Site. The mosaic was compressed using MrSID software at a 20:1 target compression ratio.
