Desktop Geographic Information System for Salmonid Resources in the ColumbiaRiver Basin

摘要

The authors developed a desktop geographic information system (GIS) of Northwestsalmonid resources in the Columbia River Basin based on a series of ArcView projects. The system includes data on chinook salmon (Oncorhynchus tshawytscha), chum salmon (O. keta), coho salmon (O. kisutch), pink salmon (O. gorbuscha), sockeye salmon (O. nerka), and steelhead (O. mykiss). Each ArcView project is catagorized into salmonid spawning escapement, hatchery releases, and presence/absence tabular data. Salmonid spawning escapement data sets are further divided by observation type (i.e., dam counts, fish per mile, etc.) and linked to
