Description:

Abstract:

Orthorectified color infrared ERDAS IMAGINE image of Appomattox Courthouse National Historical Park and surrounding parcels. Produced from 42 color infrared photos taken December 18, 2000 in leaf-off conditions. Overall positional accuracy is 1.475 meters (Euclidean distance). This meets the Class 1 NMAS map accuracy standard.

Purpose:

The dataset was created for Appomattox Courthouse National Historical Park for use in natural resource management.

Horizontal_Positional_Accuracy_Report:

Overall positional accuracy is 1.475 meters (Euclidean distance). This meets the Class 1 NMAS map accuracy standard. Horizontal accuracy was found by assessing 39 points spread throughout the orthorectified image area. These points were identified on the basemap and then were found in the field where their coordinates were taken using a Trimble ProXRS with real time data correction. The field coordinates were then compared to the coordinates from the basemap in ArcView 3.2 to determine positional accuracy.

Process_Step:

Process_Description:

The aerial photos (42 total) were used to create an orthorectified mosaic using ERDAS IMAGINE and ERDAS Orthobase. The photos were scanned at 600 dpi and imported into IMAGINE. They were then orthorectofied using four USGS DOQQ's and a USGS National Seamless Elevation DEM as reference. The DEM was resampled from 30 meters to 10 meters using ArcInfo 7.2.1. Each photo was entered into an Orthobase photo block and registered to its interior orientation. Tie points were applied and automatic tie points generated and control points were applied in the Orthobase Point Measurement Tool. Once a successful triangulation solution was reached in Orthobase, the orthorectified images were then mosaiced within IMAGINE to form one seamless basemap image for Appomattox Courthouse National Historical Park.
