| Description | A spatial database was created for the Drewes (1980) tectonic map of southeast Arizona: this database supercedes Drewes and others (2001, ver. 1.0). The west tectonic map (Drewes, 1980) was converted to digital format by Optronics Specialty Co., Inc. and |

These files are compatible with ArcView 1 and ARC/INFO Version 6.1.2 or later. The files are contained in 11 directories. Ten of those directories contain coverages for the individual quadrangle publications. The eleventh directory, "vz", contains the same information but in the form of a combined map with all the quadrangles tiled together into a single coverage. The coverages for the individual quadrangles have the same features as the combined coverage. The only differences are in some of the file names. For instance, the place names and city points in the individual quadrangles are stored in files called "*anno5.e00" as opposed to "places.e00" for the combined coverage. >ArcView views and themes coverage name >------------------------------------------------------------------- > >Venezuelan Guayana Shield, all quadrangles vz.av > >Venezuela national boundary vzctry >Venezuela province boundary vzprov >Scale bar annotation scale >Scale bar scale >Place names places >Place points places >Roads vzrd >Outer quad outline vzout >Outer quad outline, lat/long numbers vzout >Latitude/longitude tics vztc >Index map annotation index >Index map lat/long grid only grid >Index map, colored countries, lat/long grid index >Streams annotation vzst >Streams vzst >Mineral deposits deposit >Linear features annotation vzft >Linear features vzft >A.
