A Geographic Information System (GIS) is a computer system that allows the storage, analysis, creation, and retrieval of maps and geographic data. The Roanoke Valley-Alleghany Regional Commission has used GIS technology for over 25 years and offers a variety of GIS Services within the region. While most of the services are for our member local governments, we can occasionally do other projects as time and resources permit. Some of these services include:

• custom Census maps showing any demographic data from the 2000 Census;
• site-selection assistance using Census data and traffic counts;
• digital photography
• technical assistance with projections, datum and file conversions
• 1962, 1965, 1970, 1986, 1995 and 2002 aerial photos
• 2002, 2006 High resolution digital ortho-photos
• GIS analysis-overlays, viewsheds, slopes, etc.;
• CD and DVD Recording of digital data and Census data;
• paper map or photo scanning;
• sub-meter GPS capability;
• technical assistance, training, demonstrations, or troubleshooting;
• small or large full color maps for reports or plans; and
• other custom maps.

As a State Data Center Affiliate, the Commission also receives a wide variety of data on employment, education, and economics from the Commonwealth of Virginia and the U.S. Census Bureau. For more information please email us.

GPS Services

A Global Positioning System (GPS) tracks satellite movements to determine coordinates on the ground for surveying, mapping and navigation. This GPS receiver has the ability to track up to 12 satellites, and map points, lines or areas within a few feet of their actual ground location. Applications of this technology could include:

• manhole, hydrant, meter inventories;
• sign and bridge inventories;
• road centerline mapping;
• high water or burn area mapping;
• driveway or dwelling locations;
• well site mapping; and
• bus stop locations.

The technology also allows the recording of characteristics of the features in the field which can then be imported into a GIS. Trained staff are ready to meet your GPS needs.
