Description:

Abstract:

Orthorectified color infrared ERDAS Imagine image of George Washington Birthplace NM. Produced from 24 color infrared photos taken October 20, 2001 during leaf-on conditions. Orthorectification accomplished with ERDAS Imagine Orthobase v8.5 software. The overall positional accuracy for the photomosaic meets the NMAS Class 1 standards.

Purpose:

The dataset was developed for use by George Washington Birthplace NM as a GIS component and for digital monoplotting and mapping.

Horizontal_Positional_Accuracy_Report:

Overall positional accuracy of 1.54 meters: 1.07 meters in the x direction; 1.28 meters in the y direction. Meets the NMAS Class 1 map standard for x; NMAS Class 1 map standard for y. Horizontal accuracy was assessed on the basis of 20 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 180 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 (24 total) were used to create an orthorectified mosaic using Erdas Imagine. The photos were scanned at 600 dpi and imported into Imagine. The DEMs were resampled from 30 meters to 10 meters in ArcInfo Workstation using cubic convolution and then mosaicked together. If the mosaicked DEMs had gaps, they were then run in ArcInfo Workstation using a focal mean. The images were orthorectified using ERDAS Imagine Orthobase software. Airborne GPS and IMU data were used in the aerial triangulation procedure. Aerial triangulation produced a single RMSE of less than 1 meter for the entire block of photos. The orthorectified images were then mosaiced within Imagine to form one seamless basemap image for George Washington Birthplace NM. The mosaic was compressed using MrSID software at a 1:20 target compression ratio.
