The cartography section of the Oregon Department of Geology and Mineral Industries (DOGAMI) prepares a variety of maps depicting the state's geology and geologic hazards. Maps are produced primarily using the MapInfo desktop GIS software. Certain components of the maps are created in MicroStation CAD before importing to MapInfo. MAPublisher is used for final preparation if a decision is made to output for offset printing. The decision to offset print versus inkjet print in-house hinges on the perceived level of demand. New inkjet printers with their higher speed and near-photo quality production are used for quantities of under 500. When a map is projected to have the potential for large demand, offset printing is used.
Examples included in this poster display with comments on production:
Geologic Map of the Summerville Quadrangle, Union County, Oregon
Relative Earthquake Hazard Map of the Eugene-Springfield Metropolitan Area, Lane County, Oregon
- the procedure adapted for production of this multicolor geologic map with a one bit, two color Digital Raster Graphic base was sparked by discussions at DMT '98. Maps are inkjet printed in-house.
Tsunami Hazard Map of the Warrenton Quadrangle, Clatsop County, Oregon
- Polygonal data generated in MapInfo was taken into Freehand via MAPublisher. The shaded relief base was generated from 10 meter DEMs (from U.S. Geological Survey) in Vertical Mapper. Resulting files were delivered to an imagesetting service that provided color separated negatives for offset printing.
Tsunami Hazard Map of the Warrenton Area, Clatsop County, Oregon
- the production of this map series for the entire Oregon coast was mandated by the Oregon legislature as part of a public safety bill in 1995. Maps are inkjet printed in-house.
Earthquake-Induced Slope Instability: Relative Hazard Map Eastern Portion of the Eola Hills, Polk County, Oregon
- this study used base data with much higher resolution and the map is intended for evacuation planning. Maps are inkjet printed in-house.
Water-Induced Landslide Hazards, Eastern Portion of the Eola Hills, Polk County, Oregon
- this map was produced in MapInfo utilizing Vertical Mapper to do the grid-based analysis. Maps are inkjet printed in-house.
Earthquake Scenario Ground Shaking Map for the Portland, Oregon, Metropolitan Area: Portland Hills Fault M 6.8 Earthquake Peak Horizontal Acceleration (g) at the Ground Surface
- a contractor provided data in ArcView shape format, which were translated into MapInfo which was used to produce this map. Maps are inkjet printed in-house.
- a cooperative project in which a private sector firm modeled various levels of ground shaking and produced PostScript files from ArcView. This map was offset printed.
