Data and GIS/GPS Mapping Center


Ohio Valley Regional Development Commission is designated as a Regional Data Center affiliated with the Ohio Department of Development’s Office of Policy Research and Strategic Planning, The OVRDC receives all census data, publications and special reports from State and Federal agencies. 


  • OVRDC maintains comprehensive databases of national and state demographic, economic, environmental, and infrastructure data.

  • The main sources of this information are from the U.S. Census Bureau, Ohio Department of Job and Family Services, and other federal, state, and local sources.

  • This information is maintained in electronic and hardcopy formats.

  • Additional resources that OVRDC maintains are selected research reports and studies on the region and its communities.

  • Also OVRDC maintains an all-inclusive GIS database of the region from varies sources.

  • OVRDC delivers certain statistical data related to the region on our website: www.ovrdc.org

  • Additionally, the OVRDC processes requests for Census data from:

§  Local governments

§  Private sector businesses and industries

§  Educational institutions

§  Citizens

Ohio Valley Regional Development Commission maintains a geographic information system (GIS) and a global positioning system (GPS).  This GIS/GPS system is used to create an assortment of maps and conduct a variety of analysis projects.

What is GIS (Geographic Information System)?

Ø  A GIS is mapping software that links information about where things are with information about what things are like.  Simply put, a GIS combines layers of information about a place to give you a better understanding of that place. The power of a GIS over paper maps is your ability to select the information you need to see according to what goal you are trying to achieve. A full GIS, or geographic information system, requires hardware, software, data, trained users, and sound analysis methods for interpreting the results generated by the GIS.

Ø   A GIS is organized by Data Themes or Layers. Most GIS databases contain many “layers” - individual graphic data files with fields of attribute data, some of which may serve to link it with other files.

Ø  Some of the data layers that OVRDC has are: aerial photography, U.S.G.S. topographic maps, U.S. Census Tiger files, county roads, highways, parks, forest, boundaries, rivers, lakes, traffic analysis, land analysis, biological, geological, natural hazard, groundwater, oil and gas wells, and much more.





  • OVRDC maintains a variety of data on the 12 counties it serves.

  • OVRDC has a variety of records that cover the 12 county region. OVRDC’s data has come from many different sources. For example: US Geological Survey (USGS), US Department of Agriculture (USDA), Environmental Protection Agency (EPA), US Census Bureau, US Department of Transportation (USDOT), US Department of Interior, Ohio Department of Transportation (ODOT), Ohio Department of Natural Resources (ODNR), Ohio GIS Support Center, Ohio Valley Regional Development Commission, Public Utilities Commission of Ohio (PUCO), Federal Emergency Management Agency (FEMA), county offices, and private firms.

  • OVRDC has received GIS data from several county GIS’s offices through the years. Such data includes: road centerlines, pavement, ½, 1, 2, & 4 ft. resolution DOQQs, parcels, structures, boundaries, contours, soils, schools, and zoning layers.

  • OVRDC through the years has created several GIS layers of its own for different projects.

  • OVRDC has the capability through the different software extensions to create and maintain a  wide variety of data.

What is GPS (Global Positioning System)?

Ø  Global Positioning System (GPS) is a space-based radio-positioning and time transfer system constellation of 24 satellites developed, launched, and maintained by the United States Air Force that provides positioning, timing, and navigation signals free of charge to both military and civilian users worldwide. GPS satellites orbit the earth every 12 hours, emitting continuous navigation signals that enables properly equipped users to determine precise time and velocity and worldwide latitude, longitude and altitude to within a few meters. In addition to the satellites, the system consists of a worldwide satellite control network and GPS receiver units that acquire the satellite's signals and translate them into precise position and timing information. The signals are so accurate that time can be figured to much less than a millionth of a second, velocity can be figured to within a fraction of a mile per hour, and location can be figured to within a few sub-meters or better with the right equipment. The receivers do not send out any signals, or communicate back to the satellites. In addition, the FAA’s Wide Area Augmentation System (WAAS) has become a critical component of a seamless satellite navigation system which improves the accuracy, availability, and integrity of GPS. GPS has proven beneficial in the commercial and civil markets for transportation, surveying and rescue operations and are used to locate features such as manholes, fire hydrants, bridges, road centerlines, buildings, and etc.


Ø  Ohio Valley Regional Development Commission has entered the Global Positioning System (GPS) world by purchasing a Trimble GeoExplorer GeoXT GPS unit with ESRI ArcPad 6.0.3, Trimble’s GPScorrect, and Trimble’s GPS Pathfinder Office Software. The GeoXT is a submeter accuracy receiver that can track up to 12 satellites, with real time corrections from a satellite-based augmentation system (SBAS) like WAAS1 or EGNOS2. The GPS receiver and antenna are built into the handheld computer that is cable-free The GeoXT is a very powerful handheld unit that helps extend OVRDC’s GIS/GPS capabilities.
