Description:

Abstract:

Orthorectified color infrared Imagine image of Valley Forge NHP. 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.

Purpose:

The dataset was developed for use by Valley Forge NHP as a GIS component and for digital monoplotting and mapping.

Overall positional accuracy of 2.05 meters 1.26 meters in the x direction 2.84 meters in the y direction Meets the NMAS Class 1 map standard for x, NMAS Class 2 map standard for y Horizontal accuracy was assessed on the basis of 50 field survey points. 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.

Process_Step:

Process_Description:

The photos (49 total) were used to create an orthorectified mosaic using Erdas Imagine. 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.
