Abstract

ORTHO_BP contains high resolution QuickBird orthorectified satellite imagery from Digital Globe. The data are presented in 4 bands with pixel resolution of 60cm and horizontal accuracy of 2.3m.

Purpose

ORTHO_BP data were purchased to provide updated orthoimagery in the Baxter State Park region, an area which would otherwise not be covered under the GeoLibrary Board orthoimagery purchase. The imagery, at 60cm resolution and 2.3m RMS horizontal accuracy, are useful in many large-scale mapping applications for the park area.

Supplemental Information

The raw .tiff images are available upon request only to licensed entities.

Logical Consistency Report

ORTHO_BP imagery covers all of Baxter State Park plus a roughly 700-meter boundary. It was collected by the QuickBird satellite sensor Oct 3, 2004 at approximately 3:28PM local time. Pixel resolution is 60cm with horizontal RMS error of about 2.3m.

Completeness Report

The imagery collection is complete in that the entire area was imaged according to specifications.

Horizontal Positional Accuracy Report

Orthorectification was completed using 11 ground control points and 86 tie-points, using the National Elevation Dataset as the terrain reference. This resulted in imagery with a combined RMS error of 2.3m. The accuracy and quality of the Digital Globe orthoimagery meets National Map Accuracy Standards at 1:3,600 scale, plus/minus 3 meters or 10 feet, and is accurate for mapping applications at 1" = 300'.
