Produced from 85 color infrared photos taken February 28, 2002. Orthorectification accomplished with Imagine Orthobase v8.6 software. Horizontal RMSE is 1.327 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_spring.img, cold_garth_newgain_spring.img, fort_darling_spring.img, fort_harrison_spring.img, malvern_glendale_spring.img, parkers_bat_spring.img Purpose: The dataset was developed for use by Richmond National Battlefield Park as a GIS component and for digital monoplotting and mapping.

Meets the NMAS Class 1 map standard for 1:6000 scale photography. Horizontal accuracy was assessed on the basis of 24 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.
