Description:

Abstract:

Orthorectified color infrared ERDAS IMAGINE and MrSID image of New River Gorge National River (final_neri_mosaic.img). Produced from 471 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 standards.

Purpose:

The dataset was developed for use by New River Gorge National River as a GIS component and for digital monoplotting and mapping.

Horizontal_Positional_Accuracy_Report:

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 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.

Process_Step:

Process_Description:

The photos (471 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 New River Gorge National River. The mosaic was compressed using MrSID software at a 20:1 target compression ratio.
