The Washington Division of Geology and Earth Resources hosts the Washington State Geologic Information Portal where you can access interactive earth science mapping, data, and related information. [right, the prototype site for geothermal data]
More types of geologic information will be added to the information portal in the future, so please visit regularly to see what's new. You may also subscribe to our mailing list to receive announcements of new additions to the portal, as well as notification of our publications releases.
Using the interactive maps, you can create, save, and print custom maps, find out more information about map features, and download map data for use in a geographic information system (GIS). In addition to a variety of geoscience layers that can be turned on and off, each interactive map has many base layers to choose from, so you can customize your map in any number of ways. Please note that because of the volume of data available through these interactive maps, data loading and identification operations may not be instantaneous.
The site use ArcGIS Server v9.3.1 with a flex application. State Geologist Dave Norman reports they will be moving to v10 sometime next year which will likely give them more speed and a few more tools. He says the software has finally reached a stage where it is useful and fast enough for someone to consider using an interactive geology site.
The Geology mapping theme is the most advanced of the group but the others are adding data and functions continually.
