New USGS Webinar – The National Map Viewer

Hello Pacific Region GIS data users.

In our continuing series of educational GIS webinars for CA, HI, and NV, we would like to follow up the recent EarthExplorer call with one on an equally important USGS data distribution site – The National Map Viewer.

Please join us for a webinar and call on Thursday, January 30 at 11:00 HST, 1:00 PM PST. To sign up for the webinar, just visit the following link to register:
Once you have registered for the meeting, you will receive an email message confirming your registration. This message will provide the information (including conference call numbers) that you need to join the meeting. Note that our webinar capacity and phone lines are both limited to 50 people. So depending on the number of people interested, we may not be able to accommodate everyone. But we will monitor the registrations and keep you informed..

This site has lots of GIS-ready data available for free download. We will go over data access, USGS products, viewing data, and web services. Your instructors will be Carol Ostergren and Drew Decker.

From our website (
Use The National Map Viewer and Download Platform to visualize, inspect, and download our most current topographic base map data and products for free. Managed by the USGS National Geospatial Program (NGP), The National Map Viewer provides access to all eight primary data themes of The National Map to include US Topo and historical topographic map products.
Data include: Elevation, Orthoimagery, Hydrography, Geographic Names, Boundaries, Transportation, Structures, and Land Cover, while products include: US Topo and Historical Topo Maps. The National Map Viewer also allows visualization and identification queries (but not downloads) of Other Featured Data, to include Scanned Topo Maps, Ecosystems, Protected Areas, Gap Analysis Program Land Cover, Wetlands, Public Land Survey System, and National Park Service Boundaries. Also included is a Natural Hazards panel to view hazards-related information, such as for earthquakes, floods, wildfires, and weather, along with the U.S. National Grid for emergency response.

Hope you are able to join us! Contact either of us with any questions.
