Geologic Mapping Template

The Geologic Mapping Template is a collection of ArcGIS resources designed to facilitate geologic mapping. This is a collaborative effort between the U.S. Geological Survey and ESRI to implement the FGDC Digital Cartographic Standard for Geologic Map Symbolization (FGDC Document Number FGDC-STD-013-2006) in ArcGIS.

In order to most effectively portray complex geologic information, symbols and labels have been developed using cartographic representations and the Maplex label extension in ArcGIS 9.3. This Template includes 1000 of the most commonly used line and point symbols in Sections 1-18 of the Standard.

Plans for updating the Template include:

  1. Revisions to symbols as needed, based on a thorough USGS review of the Geologic Mapping Template, and on user comments;


  2. Adding about 100 FGDC symbols (from Sections 19 and 26) that were not included in the May, 2009, release of the Geologic Mapping Template; and


  3. Adding FGDC patterns intended for use in stratigraphic columns and correlation charts.

To learn how to use the Geologic Mapping Template symbology with your database schema, visit the Mapping Center and read the How to use Geologic Mapping Template symbology with your database schema. For further information or to provide comment on the GMT, please contact us through the Ask a Cartographer link on the Mapping Center website. To provide comments about the FGDC standard itself, please contact the USGS.

Legend issues   posted by geoscience6 on Jun 11, 2009 10:17 AM

Symbols work and look great. Only issue is you cannot use symbols to make a legend in ArcMap. Any faults with markers just show up as lines only when you make a legend (add the normal fault symbol to a legend...it is just a straight line). Any way around this? Otherwise, works great for digital only maps...but still must make a custom legend if you want to make a print-ready map in Arc.

If you want to plot the representation symbols in the legend, one option is to customize the feature classes that use control points as part of the Rule definition. To do this make copies of the fault and fold feature classes. Name them legend_fault and legend_fold. You can then change the control point marker placement settings for legend_fault and legend_fold from "On Vertices" to "On line," Position:0, Relative to: Line middle, Angle to line: check. After you apply the new settings, you should be able to create a new legend that displays the completed symbol.

REPRESENTATION menue   posted by LuisAlejandro on Aug 19, 2009 2:55 PM

How it is posible to run the REPRESENTATION tool?: http://www.pic2up.net/view/QfRKGdp-sig.JPG Because I can not find the way to built my own geodatabase with this tool. Is this option available for ARCGIS 9.3 users?

Please refer to the "How to use Geologic Mapping Template symbology with your database schema" Mapping Center blog. The link is provided in the template description above.
