Washington National Monument Vegetation Mapping Project Edition: 20030515-Final Geospatial_Data_Presentation_Form: remote-sensing image Online_Linkage: http://biology.usgs.gov/npsveg/ftp/vegmapping/bowa/bowaortho.zip Description: Abstract: Orthorectified color infrared ERDAS IMAGINE image of Booker T. Washington National Monument. Produced from 10 color infrared photos taken February 19, 2002. Orthorectification accomplished with IMAGINE Orthobase v8.5 software. Horizontal RMSE is 1.75 meters. This meets the NMAS Class 2 standard. Purpose: The dataset was developed for use by Booker T. Washington National Monument as a GIS component and for digital monoplotting and mapping.

Washington National Monument and surrounding area Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Overall positional accuracy of 1.75 meters RMSE meets the NMAS Class 2 map standard. Horizontal accuracy was assessed on the basis of 18 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 post-processed using differential correction. The field coordinates were then compared to the image mosaic coordinates for these points, determined in ESRI ArcView 3.3 software.

Washington National Monument Process_Step: Process_Description: The photos (10 total) were used to create an orthorectified mosaic using ER Mapper 6.2. 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. 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 ER Mapper 6.2 to form one seamless basemap image for Booker T. Washington National Monument. The mosaic was compressed using MrSID software at a 20:1 target compression ratio.
