Description:

Abstract:

This coverage is a land cover map of the lower Dungeness river watershed, northern Olympic peninsula, Washington, USA. Land cover categories were done based on distinguishable photo characteristics only, and did not include soils, land tenure, or other sources of information. It was done based on what was visible the day the photos were flown. Land cover was classified based on water use. Thus all kinds of (unirrigated) forest were lumped together as forest if their crowns were closed, while an area of grass might be lawn, field, grassy/brushy, or pasture, depending on its apparent use.

Purpose:

The purpose of this coverage is to be a part of a time series of coverages which show land cover and water use changes in the lower Dungeness watershed from 1859 to 1994

Supplemental_Information:

More detailed information about these coverages is available in Penelope Eckert's Phd Thesis, University of Washington, College of Forest Resources, June 1998.

These contact print stereo photos are used to determine the location and extent of the different land covers within the study area

Process_Step:

Process_Description:

This coverage is a directly digitized coverage, derived from aerial photographic interpretation and land use classification. This interpretation used the 1:12,000 DNR stereo photos for 1990. The classification was done based on distinguishable photo characteristics only, and did not include soils, land tenure, or other sources of information. It was done based on what was visible the day the photos were flown. Land cover was classified based on water use. Thus all kinds of (unirrigated) forest were lumped together as forest if their crowns were closed, while an area of grass might be lawn, field, grassy/brushy, or pasture, depending on its apparent use. Classifications were made based on a one-acre minimum size, though isolated buildings and lawns of much smaller size were routinely distinguished when widely separated. Land cover classes were transferred with a monocular zoom transfer scope to a base map.

Process_Step:

Process_Description:

The georeferenced, orthorectified base map was derived from DNR landlines contained in the POCA coverages for the area. Road locations as specified in the Clallam County trsqmx coverage were used for orientation. Land classifications derived from 1:12,000 stereo aerial photography taken in 1990 were first delineated and transferred. After update was completed, the dissolve function in Arc was used to create a coverage where adjacent polygons with the same land cover code were joined into one polygon.

Detailed_Description:

Entity_Type:

Entity_Type_Label: Land Cover

Entity_Type_Definition:

Land cover is the type of surface features that appear to exist within the study area. Land cover does not imply land use. For example, land use for "bare" lands varied from active gravel mines to protected park beaches and from highway right-of-way fill slopes to the shifting sediments of the Dungeness River bed. This land cover classification was done based on distinguishable photo characteristics only, and did not include soils, land tenure, or other sources of information. It was done based on what was visible the day the photos were flown. Land cover was classified based on water use. Thus all kinds of (unirrigated) forest were lumped together as forest if their crowns were closed, while an area of grass might be lawn, field, grassy/brushy, or pasture, depending on its apparent use.

Enumerated_Domain_Value: 10 = ba = bare

Enumerated_Domain_Value_Definition:
