Oahu Land Use 1998

This is a vector GIS coverage (ESRI ArcInfo format) of the land use of the island of Oahu, 1998, derived from multiple sources of digital orthophotos.

The USGS National Water-Quality Assessment Program (NAWQA) is designed to describe the status and trends in the quality of the Nation's ground- and surface-water resources and to provide a sound understanding of the natural and human factors that affect the quality of these resources (Leahy and others, 1990). The Oahu NAWQA program began in October 1998.  The land-use data provided here are intended for analysis in conjunction with

the Oahu NAWQA water-quality data.

The land uses identified are those that involve surface modification through human activity.  These are referred to herein as agriculture, developed (urban), or barren-mining.  Other land uses, including conservation, forest, natural areas, wetlands, water, and barren (sand, rock, or soil), and un-managed vegetation are identified as "other". This coverage is derived from 1-meter ground resolution digital orthophotos (DOQs) and intended for use at 1:24,000-scale or smaller.
