Abstract

This is an OGC-compliant web map service (WMS) of true color orthophotos for the Katahdin Lake region of Maine, adjacent to and east of Baxter State Park. The orthos were collected May 9, 2006, for the Department of Conservation by the James W. Sewall Company of Old Town, Maine. The purpose of the collection was to evaluate options for conservation of land adjacent to Baxter State Park. The data were collected at an average elevation of 7920', using a Zeiss RMK TOP 15 camera and AGFA X100 color negative film. Negatives were scanned at resolutions of 14 and 28 microns, for an intended scale of 1:15,840. The digital orthos have a ground pixel resolution of one half meter (0.5m).

Purpose

To visually evaluate the land adjacent to Baxter State Park under various conservation scenarios.

Completeness Report

The data are complete, have been reviewed and accepted.

Horizontal Positional Accuracy Report

The data are intended for use at a scale of 1:15,840 and meet ASPRS accuracy standards for that scale (approximate horizontal error of 3.75m or less 95% of the time).

Process Description

The area was flown by James W. Sewall Company on May 9, 2006, at an elevation of 7920' with no cloud cover, using a Zeiss RMK TOP 15 camera (with a valid camera calibration report submitted to USGS) and AGFA X100 Color Negative film. The resulting color negatives were scanned at 14 and 28 microns. Orthophotos were prepared by Sewall to meet accuracy specifications for scale of 1:15,840. The resulting TIFFs were delivered to the Maine Department of Conservation. The tiles were retiled to 1km x 1km blocks and compressed to JPEG2000 by Maine Office of GIS staff for presentation as WMS. Metadata were compiled by MEGIS staff from information provided by Sewall.
