Produced from 109 color infrared photos taken October 23, 2001. Orthorectification accomplished with Imagine Orthobase v8.6 software. Horizontal RMSE is 1.098 meters. This meets class 1 NMAS for 1:6000 scale photography. Richmond National Battlefield Park is broken into 6 pieces due to space constraints. The 6 individual pieces are listed as follows: beaverdam_chick_fall.img, cold_garth_newgain_fall.img, fort_darling_fall.img, fort_harrison_fall.img, malvern_glendale_fall.img, parkers_bat_fall.img The dataset was developed for use by Richmond National Battlefield Park as a GIS component and for digital monoplotting and mapping. 20011023 ground condition Complete Unknown Richmond National Battlefield Park and environs -77.445811 -77.222133 37.607048 37.340441 none Orthorectified Color Infrared mosaic aerial photo CIR image leaf-on none Virginia National Park Richmond National Battlefield Park none 20011023 fall October none none Mike Andrus Richmond National Battlefield Park Ranger mailing and physical address

Richmond Virginia 23223 USA (804) 226-1981 mike_andrus@nps.gov Bill Millinor ERDAS Imagine IMG File and MrSID Compressed File Raster Data Richmond National Battlefield Park and surrounding area Overall positional accuracy of 1.0987 meters RMSE. Meets the NMAS Class 1 map standard for 1:6000 scale photography. Horizontal accuracy was assessed on the basis of 25 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 ArcView 3.3 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 to remove the gaps. 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 six seamless basemap images for Richmond National Battlefield Park. The mosaics were compressed using MrSID software at a 20:1 target compression ratio. 200301 NCSU, Center for Earth Observation mailing address
