Geoscience in Your State: Ohio

Interactive database for geologic maps of the United States

The U.S. Geological Survey hosts the National Geologic Map Database (NGMDB). This interactive tool serves as a national archive for high-quality, standardized geologic maps created by the U.S. Geological Survey and state geological surveys.

The MapView section of the NGMDB displays geologic maps from across the country dating back to 1879. The database is searchable by address, and results can be narrowed further using scale and date filters.

Interactive database for topographic maps of the United States

The U.S. Geological Survey hosts topoView, an interactive database of the survey’s topographic maps.

The map is searchable by address, and clicking on any point on the map brings up topographic maps of the area dating back to 1879. Map results can be narrowed further using scale and date filters.

Clicking the “show” option will overlay the selected map onto the coordinates of topoView’s base map. Adjusting the map overlay transparency allows comparison of historical and present-day topography.

All maps in topoView are downloadable in multiple formats.

Interactive map of groundwater monitoring information in the United States

The National Ground-Water Monitoring Network compiles information from over 7,000 groundwater monitoring wells across the country, including Federal, State, and local groundwater monitoring networks. Although the image above only shows the contiguous United States, the interactive map also includes wells from Alaska, Hawaii, Puerto Rico, Guam, and the U.S. Virgin Islands.

Interactive map of hazardous waste cleanups in the United States

The U.S. Environmental Protection Agency (EPA) provides an interactive map of hazardous waste cleanups across the United States. The "Cleanups in My Community" map provides a huge amount of information on thousands of cleanups of many kinds. For every cleanup, users can access and download reports, assessments, compliance actions, and the EPA's assessment of the potential for any contaminated land to be used for renewable energy development.

Geologic Mapping to Empower Communities: Examples from the Great Lakes

Wednesday, December 6, 2017

Less than one-third of the U.S. is mapped at the level of detail necessary to make informed planning decisions on a local scale concerning natural resources, natural hazards, infrastructure planning, and environmental stewardship. In the Great Lakes region, the Great Lakes Geologic Mapping Coalition (GLGMC), a group including U.S. and Canadian state and provincial geological surveys, is producing detailed 3D geologic maps that are helping to provide decision-relevant information to Great Lakes state communities. Due to similar regional geology, these state surveys can work together, sharing their expertise and resources so that each can better address geologic issues in their area. Working with the communities, the GLGMC provides and makes maps that solve problems such as groundwater contamination and resource development.

Interactive map of coal resources in the United States

The U.S. Geological Survey's National Coal Resources Data System comes with an interactive map that provides a huge amount of information on the distribution, thickness, and classification of coal in the United States.

The interactive map contains over 250,000 data points, each typically representing a core sample, drill hole, or driller's log in a specific location. You can use the "Filter" tool to focus in on specific areas, or on data collected by specific organizations. Commonly available data include:
