Geologic Map Creation

Geologic Map Creation- Colorado State Geologic Survey Mapping

Colorado Department of Natural Resources Colorado Geological Survey The Colorado Geological Survey (CGS) is a state agency within the Colorado Department of Natural Resources. Its mission is to help reduce the impact of geologic hazards, promote responsible economic development of mineral and energy resources, provide geologic insight into water resources, and to provide geologic advice and information to a variety of constituencies.
State Geologic Survey Mapping Component (STATEMAP) is one of three components of the National Cooperative Geologic Mapping Program (NCGMP). Geologic maps produced as part of Colorado's STATEMAP program are used by geoscience professionals and by planners and decision-makers at the state, county, and municipal levels of government.  Digital Data Services, Inc (DDS) was hired by the Colorado Geological Survey to produce eight publication quality geologic maps for the Colorado STATEMAP program.

Data was provided by CGS-contracted geologists to be compiled into a geologic report that typically consisted of two plates and a report. Geologists collected field data utilizing GPS-units and created geologic unit features from aerial photography. Field data and geologic units were provided to DDS for cleaning and symbolization. Creating the map plates utilized geologic units, faults, anticline and synclines, strikes and dips, and various other geologic features.
Geologic plates were created by utilizing a “cleaned” USGS topographic quadrangle. Geologic units were processed to create a topologically correct layer. Where map were adjacent to other mapped quadrangles, polygons were edge-matched. All datasets were converted to a standardized format. Final output included both Adobe Acrobat PDF versions and complete datasets for use in ESRI ArcGIS or ESRI ArcReader.

Information from these maps is regularly incorporated into decision-making on a wide variety of local and county-wide issues that include indentifying geologic hazards, protecting ground water resources, locating new municipal wells, siting waste-disposal facilities, identifying potential aggregate resources, and addressing a broad spectrum of land-use concerns.
