A color orthophoto mosaic was developed from a set of digital 1:8,000 scale color infared aerial images taken April 28, 2003. The final horizontal positional accuracy of the Marsh-Billings-Rockefeller National Historical Park mosaic is 4.02 meters RMSE. Produced from 14 color infrared photos. Orthorectification accomplished with Imagine Orthobase v8.7 software. The dataset was developed for use by Marsh-Billings-Rockefeller National Historical Park as a GIS component and for digital mapping. 20030428 ground condition Complete None planned Marsh Billings Rockefeller National Historic Park and environs -72.558803 -72.499193 43.648466 43.618391 none Orthorectification Color Infrared mosaic aerial photo CIR IMAGINE leaf-off National Park Service Theme Category Thesaurus Digital orthophoto none Vermont National Park National Historical Park Marsh-Billings-Rockefeller National Historical Park National Park System Unit Name Thesaurus Marsh-Billings-Rockefeller National Historical Park National Park System Unit Code Thesaurus MABI none 200304 spring April none none National Park Service, Northeast Region, Northeast Temperate Network Network Data Manager mailing

PDF Aerial photography was flown by William Frament, USDA Forest Service, Northeastern Area State and Private Forestry, Durham, NH. Orthophoto mosaic was produced by William Millinor, North Carolina State University, Center for Earth Observation, Raleigh, NC. Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 3; ESRI ArcCatalog 9.2.6.1500 none none Overall positional accuracy of 4.02 meters RMSE. Horizontal accuracy was assessed on the basis of 24 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.

The photos were scanned at 600 dpi and imported into Imagine. The DEM was resampled from 30 meters to 10 meters. The individual DOQQs were mosaiced to create a single file for use as ground control. The images were orthorectified in ERDAS Imagine Orthobase software using the DOQQs and the DEM as ground control. 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 to form one seamless basemap image for Marsh-Billings-Rockefeller National Historical Park. The mosaic was compressed using Mr. SID software at a 1:20 target compression ratio. 200406 NCSU, Center for Earth Observation mailing address
