DOGAMI’s interactive maps, GIS data, and map services help Oregonians better understand our state’s geology and geologic hazards.

Interactive Maps

Hazards

HazVu, Oregon Statewide Geohazards Viewer, shows landslide, flood, tsunami, coastal erosion, earthquake shaking, fault, and volcano geohazards.

Landslides

SLIDO, Statewide Landslide Information Database for Oregon, shows landslides that have been identified on published maps.

Tsunami Evacuation

Tsunami Evacuation Zones shows tsunami evacuation zones along the Oregon coast.”.

Lidar Data

Lidar Data Viewer shows shaded relief imagery for Oregon.

Geothermal

GTILO, Geothermal Information Layer for Oregon,
shows features of thermal springs and wells and direct-use areas.

Minerals

MILO, Mineral Information Layer for Oregon, shows information regarding mineral occurrences, prospects, and mines.

Oil and Gas

Oil and Gas Well Log Viewer shows the status and location of wells in Oregon and provides links to log files.

Mount Hood Hazards

Mount Hood Hazards Viewer shows multi-hazard and risk information for the Mount Hood region.

Geology

Geologic Data Viewer
 
Coming soon.

 

DOGAMI interactive maps provide general information about Oregon’s geology and geologic hazards and are not intended to be used for site-specific planning or to replace site-specific investigations.

How to Use Map Services

To use a web service, you must have a GIS application like Esri ArcMap, Esri ArcGIS Online, Google Earth, or MN Mapserver.

To connect to a WMS (web map service) in Esri ArcMap 10.1:

  1. In ArcMap, click "Add Data" button
  2. In the Add Data dialog box, select "GIS Servers"
  3. Select "Add ArcGIS Server"
  4. Select "Use GIS Services" and click "Next"
  5. Enter the URL for the server, e.g.: http://www.oregongeology.org/arcgis/services/
    (no username or password are needed)
  6. Click "Finish"
  7. Double-click on "arcgis on www.oregongeology.org (user)" to see a list of data layers
  8. Select a layer to add, e.g., ORAqueousChemistry1_10

To connect to a WFS (web feature service) in Esri ArcMap 10.1:

  1. Make sure the Data Interoperability extension has been installed
  2. In ArcMap, click the "Add Data" button
  3. Click the Look in drop-down menu and select "Interoperability Connections"
  4. Choose a WFS service from your list of WFS connections, e.g.:http://www.oregongeology.org/arcgis/services/ORAqueousChemistry1_10/MapServer/WFSServer
    to add the service's contents as a feature layer

To connect to a KML (keyhole markup language) file:

  1. Click on the KML file link in the browser window
  2. When prompted, either save the file to your local drive or select an application capable of consuming KML files (e.g., ArcGIS Explorer, ArcGlobe, and Google Earth) to open the KML file
