Abstract

Advancing Geology: From Data Creation to Map Production
Track: Cartography and Map Production
Authors: Rachel Lyles

The Oregon Department of Geology and Mineral Industries (DOGAMI) has been creating geology data and maps for many years. However, the processes from which the geologists create these products have continually evolved. From software packages to new file structures; USGS 7.5' Quadrangles to LiDAR derivatives; and simple symbology to cartographic representations: DOGAMI's entire methodology has undergone significant changes in order to produce a better product.
These transformations have enabled the geologists to create more accurate data with less errors. The database mangers have also moved from individual files (shapefiles and tables) to robust geodatabases with built-in topologies and relationship classes that can also be integrated into DOGAMI's statewide legacy geology database. Finally, the cartographers are creating more standardized maps using Esri's geologic template with cartographic representations. This presentation will highlight the conversion processes and the tests and strategies that were developed in order to move to the techniques currently employed.
