GeoModeller utilizes a Digital Terrain Model, surface geological linework, cross-sections, geophysical interpretation and drillhole borehole data to enable the geologist to construct cross sections, or 3D models. 3D Geostatistical interpolation (co-kriging) using all the data (location of interface, dip, direction, ...) produces a 3D implicit function representing a solid model.
In 1938 a new 1:500,000-scale geologic map was published. During the 1940s and 1950s, the Division developed as a state geological survey and two well-defined branches were established: the Mining Engineering Branch and the Geology Branch. The Division began processing numerous geological quadrangle maps and reports for publication.
1) It directs the state's California Geological Survey agency (then known as the California Division of Mines and Geology) to compile detailed maps of the surface traces of known active faults. These maps include both the best known location where faults cut the surface and a buffer zone around the known trace(s);
In the 21st century, computer technology and software are becoming portable and powerful enough to take on some of the more mundane tasks a geologist must perform in the field, such as precisely locating oneself with a GPS unit, displaying multiple images (maps, satellite images, aerial photography, etc.), plotting strike and dip symbols, and color-coding different physical characteristics of ...
The second geologic map of the state was published in 1916 and shows twenty-one stratigraphic regions. The State Mining Bureau was renamed the Division of Mines and Geology in 1862. Its pseudonym, the California Geologic Survey, was established in January 2002. [15]
CGS is California's primary source of geologic and seismologic products and services for decision making by California's government agencies, its businesses and the public. [1] Since the 1960s, when it was known as the California Division of Mines and Geology, CGS has produced many maps that depict landslide features and potential slope-failure ...
A geological survey is the systematic investigation of the geology beneath a given piece of ground for the purpose of creating a geological map or model.Geological surveying employs techniques from the traditional walk-over survey, studying outcrops and landforms, to intrusive methods, such as hand augering and machine-driven boreholes, to the use of geophysical techniques and remote sensing ...
