Description:

Abstract:

Orthorectified color infrared ERDAS Imagine image of Johnstown Flood National Memorial (jofl_final.img). Produced from 14 color infrared photos taken April 13, 2003. Orthorectification accomplished with Imagine Orthobase v8.6 software. RMSE is 1.047 meters meeting class 1 NMAS.

Purpose:

The dataset was developed for use by Johnstown Flood National Memorial as a GIS component and for digital monoplotting and mapping.

Horizontal_Positional_Accuracy_Report:

Overall positional accuracy of 1.047 meters Horizontal accuracy was assessed on the basis of 33 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 ArcView 3.3 software.

Process_Step:

Process_Description:

The photos (14 total) were used to create an orthorectified mosaic using ER Mapper 6.4 and Erdas Imagine 8.6. The photos were scanned at 1200 dpi and imported into Imagine. A 30 meter DEM was download from the NED and then resampled to 10 meters. The images were orthorectified using ERDAS Imagine Orthobase software and Airborne GPS and IMU data. The orthorectified images were then mosaiced within ER Mapper to form one seamless basemap image for Johnstown Flood National Memorial . The mosaic was compressed using Mr. SID software at a 1:20 target compression ratio.
