Produced from 383 color infrared photos taken October 19, 2001. Orthorectification accomplished with IMAGINE Orthobase v8.5 software. RMSE is 1.099 meters meeting class 1 NMAS. Fredericksburg and Spotsylvania NMP has been broken into 5 pieces due to space constraints. The 5 pieces are labeled as follows: frsp_fall_falm.img, frsp_fall_fmf.img, frsp_fall_guinea.img, frsp_fall_spot.img, frsp_fall_wild.img. Purpose: The dataset was developed for use by Fredericksburg and Spotsylvania National Military Park as a GIS component and for digital monoplotting and mapping.

Horizontal accuracy was assessed on the basis of 22 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 180 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 software.

The photos were scanned at 600 dpi and imported into IMAGINE. The DEMs were resampled from 30 meters to 10 meters in ArcInfo Workstation using cubic convolution and then mosaicked together. If the mosaicked DEMs had gaps, they were then run in ArcInfo Workstation using a focal mean. 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 IMAGINE or Er Mapper to form 5 seamless basemap images for Fredericksburg and Spotsylvania National Military Park. The mosaics were compressed using MrSID software at a 20:1 target compression ratio.
