Geological data that are used for a broad range of academic and practical applications, including growth-management planning, dam safety, hazard and risk assessment, water resource appraisals, resource use and protection, education, recreation, and scientific research.<\/span><\/p>

This dataset portrays the geology of Washington State at a scale of 1:100,000 (1 inch equals approximately 1.58 miles). The purpose is to make the geology of the state available as a seamless dataset for use in regional spatial analyses and other digital applications and for providing a framework for planning and land management and evaluating geologic hazards and resources. It was prepared in cooperation with the U. S. Geological Survey (USGS) National Geologic Mapping Program.<\/span><\/p><\/div>", "summary": "1:100,000-scale surface geology coverage for the state of Washington.", "title": "100k Surface Geology", "tags": [ "geologic unit", "geologic mapping", "map coverage", "WA" ], "type": "Map Service", "typeKeywords": [ "ArcGIS", "ArcGIS Server", "Data", "Map Service", "Service" ], "thumbnail": "", "url": "", "extent": [ [ -124.930115936499, 45.481022463454 ], [ -116.708446932546, 49.0500734207188 ] ], "minScale": 0, "maxScale": 1.7976931348623157E308, "spatialReference": "NAD_1983_HARN_StatePlane_Washington_South_FIPS_4602_Feet", "accessInformation": "Washington Geological Survey, 2025, Surface geology, 1:100,000--GIS data, December 2025: Washington Geological Survey Digital Data Series DS-18, version 4.0, previously released November 2016.", "licenseInfo": "", "portalUrl": "" }
