Produced from 37 color infrared photos taken April 4, 2002. Orthorectification accomplished with Imagine Orthobase v8.5 software. The overall positional accuracy for the photomosaic meets the NMAS Class 1 standards. Purpose: The dataset was developed for use by Hopewell Furnace NHS as a GIS component and for digital monoplotting and mapping.

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. 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 to form one seamless basemap image for Hopewell Furnace NHS. The mosaic was compressed using Mr. SID software at a 1:20 target compression ratio.
