UNAVCO IDV: Geology maps and vertical cross sections UNAVCO IDV: Geology maps and vertical cross sections

Geology maps from WMS servers

Geology maps from WMS servers can be included in any IDV display, with any map projection, in 2D or 3D views.

Sample USGS Data sets:

For more online data from the USGS see Mineral Resources On-Line Spatial Data

and USGS Geology online which includes

and USGS Web Map Services (WMS) available which includes gravity and magnetic anomaly maps.

OneGeology: see OneGeology and IDV Geologic Maps from WMS Servers.

Geology maps from images

Geology maps (as images) can be included in IDV displays, and geology cross sections can be included in 3D IDV displays, with the correct location and depth extent.

If you have an image of a geology map in a TIFF or JPEG file, with known corner locations, in latitude/longitude,elevation, you can display it in the IDV in the correct mapped location. See Mapping TIF imagery

You can also drape the geology map over 3D topograhic relief, if you have elevation data.

Geology Cross-Sections

Maryland geology: The surface 3D relief has been moved down to show the cross-section.

Learn more about TIF Images and TIF over Topography in 3D relief in the IDV, and learn about JPEG Images mapped with latitide and longitude.

Any image can be displayed in the IDV if you know the lat/long of the corners, either as a flat image at any level, or drapped over surface (or other) elevation data.

Geological cross sections, or any can be a vertical part of IDV displays in correct spatial and vertical location and extent. See Display vertical images.

The One Geology project provides geology maps of the world, from other geological surveys, in standard format (GeoSciML). The IDV can display these maps: OneGeology Maps server and the IDV.
