Produced from 98 color infrared photos taken March 27, 2003. Orthorectification accomplished with Imagine Orthobase v8.6 software. The overall positional accuracy for the photomosaic is 1.31 meters RMSE, meeting the NMAS Class 1 standard. The dataset was developed for use by Gauley River National Recreation Area as a GIS component and for digital monoplotting and mapping. 20030327 ground condition Complete Unknown Gauley River National Recreation Area and environs -81.138848 -80.867401 38.246823 38.135477 none Orthorectification Color Infrared mosaic aerial photo CIR IMAGINE leaf-off none West Virginia National River Recreation Area National Park Gauley Gauley River none 20030327 spring March none none National Park Service, Northeast Region, Inventory and Monitoring Program, Eastern Rivers and Mountains Network (ERMN) Data Manager mailing and physical address

PDF Bill Millinor, North Carolina State University ERDAS IMAGINE .img File and MrSID Compressed File none Gauley River National Recreation Area Overall positional accuracy of 1.31 meters RMSE. Horizontal accuracy was assessed on the basis of 147 field survey points distributed throughout New River Gorge National River, Bluestone National Scenic River and Gauley River National Recreation Area. Accuracy assessment for the above three parks was calculated as a single unit (not split up into three separate groups) as they were all flown together with airborne GPS and IMU. 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 ArcView 3.3 software. Sanborn Mapping Company, Inc Unpublished Material remote-sensing image 12000 color IR aerial transparencies 20030327 ground condition photos Aerial view of Gauley River National Recreation Area The photos (98 total) were used to create an orthorectified mosaic using ER Mapper 6.4 and ERDAS IMAGINE 8.6. The photos were scanned at 600 dpi and imported into IMAGINE. A DTM was created from the block DTM extraction process in ERDAS IMAGINE. The images were orthorectified using ERDAS IMAGINE Orthobase software and airborne GPS and IMU data. The orthorectified images were then mosaicked within ER Mapper to form one seamless basemap image for Gauley River National Recreation Area. The mosaic was compressed using MrSID software at a 20:1 target compression ratio. 200402 North Carolina State University, Center for Earth Observation mailing address
