Is there a mine nearby? What kind of rock are you sitting on? Geograph GA is the edition of the popular GIS (geographic information system) covering the state of Missouri. It is a self-contained application (no Internet or cellular access required) that contains a vast amount of information about the geography and geology of the Show Me State. You can combine various data layers, zoom in and out, and get a lot of details about the physical and human geography of Missouri. While this is a professional-grade tool, it can easily be used by anyone curious about their environment. This release has 41 layers (and new layers are frequently added). Installed by default are: - states outlines - the complete geological map from USGS - surficial materials and faults - terrain elevation and ocean bathymetry - zip codes - over 6,000 named features (summits, tunnels, cliffs, bridges, etc...) with link to USGS information page - U.S. congressional districts with link to representatives' web sites - over 12,000 mineral resources with link to USGS web site - active mines - public land ownership - hydrologic units - EPA ecological regions - 1,300 USGS quadrangles - urban areas - seismic risk - earthquakes - counties with link to census data - hydrology - roads and major streets - railroad tracks - UTM zones and state plane zones - main aquifers with link to EPA web site Layers that can be downloaded from the application include: - state House districts with link to representatives' web sites - state Senate districts with link to senators' web sites - all school districts - boundaries of cities and villages with link to census data - town boundaries - landmark areas (parks, campgrounds, airports, etc...) - landmark points (schools, hospitals, fire stations, etc...) - airports with link to FAA data pages for each airport - over 12,000 geodetic points with link to the National Geodetic Survey details pages - national park boundaries with link to the National Park Service web page for each park - railroad crossings with link to details page from the Federal Railroad Administration - floodable areas from FEMA (premium content) - 1,337 National Register Historic Places - almost 500,000 streets and roads (by county) Each layer contains additional information about its features. For instance, the geology layer has a description of the unit's name, age range, rock type, and description. Each mine has a name, a commodity, a facility type, and a company name.
