Produced from 49 color infrared photos taken September 1999. Orthorectification accomplished with Imagine Orthobase v8.4 software. Orhtophoto mosaic created in ER Mapper 6.4. The dataset was developed for use by Valley Forge NHP as a GIS component and for digital monoplotting and mapping. 19990912 ground condition Complete Unknown Valley Forge National Historical Park and environs -75.473613 -75.414876 40.124383 40.077012 none Imagine Color Infrared mosaic aerial photo Orthobase none Pennsylvania National Historical Park National Park Valley Forge none 1999 leaf-on September none none Brian Lambert Valley Forge NHP Natural Resource Manager mailing address

The actual field coordinates for these points was recorded with a Trimble ProXRS GPS unit with real-time differential correction. The field coordinates were then compared to the image mosaic coordinates for these points, determined in ESRI ArcView 3.2 software.

The photos were scanned at 600 dpi and imported into Imagine. The DEMs were resampled from 30 meters to 10 meters and mosaicked together. The images were orthorectified using Imagine Orthobase software. 100 manual tie points, 4642 automatically collected tie points, and 114 ground control points (using the DEMs and DOQQ as reference) were used in an aerial triangulation procedure. Aerial triangulation produced a single RMSE of less than 1 meter for the entire block of photos, and also predicted coordinates for all 4856 points. The photos were orthorectified in a batch process based on this solution. The orthorectified images were then mosaiced within ER MApper 6.4 to form one seamless basemap image for Valley Forge NHP. The mosaic was compressed using Mr. SID software at a 1:20 target compression ratio. 200412 NCSU, Center for Earth Observation mailing address
