Produced from 3 color infrared photos taken April 28, 2003. Orthorectification was accomplished with IMAGINE Orthobase 8.7 software. The overall positional accuracy for the photomosaic is 2.77 meters RMSE. The dataset was developed for use by Sagamore Hill National Historical Park as a GIS component and for digital monoplotting and mapping. 20030428 ground condition Complete Unknown Sagamore Hill National Historic Site and environs -73.510770 -73.487701 40.894995 40.878130 none Orthorectification Color Infrared mosaic aerial photo CIR IMAGINE leaf-off none New York National Historical Park National Park Sagamore Hill none April spring 2003 none none Sara Stevens Data Manager, Northeast Coastal and Barrier Network mailing and physical address

PDF Bill Millinor, Angela Hubbs ERDAS IMAGINE .img File and MrSID Compressed File none Sagamore Hill National Historic Site Overall positional accuracy of 2.77 meters RMSE. 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 120 (180 unless field conditions were poor) fixes per point. The field coordinates were then compared to the image mosaic coordinates for these points, determined in ESRI ArcMap 9.0.

The photos were scanned at 600 dpi and imported into IMAGINE. The DEM was resampled from 30 meters to 10 meters. The individual DOQQs were mosaicked to create a single file for use as ground control. The images were orthorectified in ERDAS IMAGINE Orthobase software using the DOQQs and the DEM as ground control. Aerial triangulation produced a single RMSE of less than 1 meter for the entire block of photos. The orthorectified images were then mosaicked within ER Mapper to form one seamless basemap image for Sagamore Hill National Historic Site. The mosaic was compressed using MrSID software at a 20:1 target compression ratio. 200409 North Carolina State University, Center for Earth Observation mailing address
