**Public   Review Draft – Digital Cartographic Standard for Geologic Map Symbolization   (PostScript Implementation)**

**Prepared   in cooperation with the Geologic Data Subcommittee of the Federal Geographic   Data Committee**

**U.S.   Geological Survey**

| **NOTE:  Please be advised that this Public Review Draft standard has been superseded by the now-official "FGDC Digital Cartographic Standard for Geologic Map Symbolization."  A *substantial number of revisions to the standard*were necessitated by the public's comments to the Public Review Draft, increasing the number of symbols from about 1,200 to almost 2,400.  The revised standard was approved by the FGDC as the Federal standard (FGDC Doc. No. FGDC-STD-013-2006) in August 2006.  The symbols in the standard are available as EPS vector graphics in the "FGDC Digital Cartographic Standard for Geologic Map Symbolization (PostScript Implementation)," which has been published as a USGS Techniques and Methods report (available at https://pubs.usgs.gov/tm/2006/11A02/).** |

To assist in the review   of the "Public Review Draft – Digital Cartographic Standard for Geologic   Map Symbolization," a PostScript implementation of the proposed standard   has been prepared. The symbols are included in EPS files that can be downloaded   here.

To review this standard,   please go to the Geologic Data Subcommittee's Web site, which contains all necessary instructions and materials for your review.   Your comments and suggestions will be used to improve the draft standard. Please   visit the site and give us your feedback.

In order to help you locate   the symbols in which you are interested, we have prepared a PDF version of each   EPS file. To view a PDF file of the appendix section containing a particular   group of symbols, click on the appropriate section title shown below.

For help in locating a particular   symbol, please see the detailed index of symbols included in the introductory   text. General guidelines on symbol usage, as well as on color design and   map labeling, are also found there.

The EPS files can be downloaded   by following the links in the PDF document that makes up each section. The   name of the EPS file that contains the geologic map symbols is shown in red   in the upper right-hand corner of each page of every PDF document. These names   are links to the EPS files containing the symbols.
