[ Update this Record ]

Summary
Abstract: In the spring of 1992, the Pacific Northwest Region of the National Park
Service contracted with Pacific Meridian Resources to develop and produce a
comprehensive GIS vegetation land cover and geomorphic landform database for
Crater Lake National Park. The study was designed to develop a comprehensive,
consistent inventory and mapping of the vegetation and landform characteristics
for the park using digital Landsat Thematic Mapper (TM) satellite imagery and
field collected data as the primary information bases.

This study was intended to provide existing vegetation and landform databases
for the project areas and demonstrate the effectiveness of Pacific Meridian
Resources' procedures for producing those databases.

Quality Accuracy assessment procedures fall into three steps: 1) sample selection 2)
labeling of reference and map sites and 3) generation of error matrices and
estimates of accuracy. A population of vegetation polygons 5 acres or greater
from which to sample was generated from the unclassified Landsat TM imagery
using Image Segmentation. The resulting polygons were then overlaid ... View entire text
