Abstract:
Conversion of the Venezuela maps to a computerized digital format was undertaken for the following reasons: 1) The digital format facilitates the presentation and analysis of earth-science data. Digital maps can be displayed at any scale or projection, whereas a paper map has a fixed scale and projection. However, the maps on this disc are not intended to be used at any scale more detailed than 1:500,000. A geographic information system (GIS) allows combining and overlaying of layers for analysis of spatial relations not readily apparent in the standard paper publication. Digital data on geology, geophysics, and geochemistry can be combined to create useful derivative products. 2) The digital format was used to facilitate publication in both paper and electronic form. For the Rio Caura paper map publication (Brooks and others, 1995), digital images were sent to the Gerber plotter, a vector-to-film processor. The other 1:500,000-scale MF maps were reproduced photographically from electrostatic plotter output on clear mylar. The published digital formats include this CD-ROM and ARC/INFO Export files to be located on the World Wide Web on the Internet. The data in this CD-ROM are based on a mineral resource assessment of the Venezuelan Guayana Shield, conducted between 1987 and 1991 by the U.S. Geological Survey and Corporacion Venezolana de Guayana, Tecnica Minera, (USGS, 1993). The Venezuelan Shield occupies about 415,000 sq km in the south and east part of Venezuela. The study area is bounded on the north by the Rio Orinoco. It includes all of the Territorio Federal Amazonas, Estado Bolivar, and part of Estado Delta Amacuro. The original resource assessment publication USGS Bulletin 2062 consists of 121 pages of text and figures as well as eight full-color maps: Geographic Geologic and tectonic Bouguer gravity Two mineral-occurrence maps Side-looking airborne radar image Two permissive domain maps The side-looking airborne radar image and the Bouguer gravity map are not included in this CD-ROM. The geology layer from the 1993 Bulletin was revised and published as a series of MF and I maps.
