GPS is an acronym for Global Positioning System. A GPS is a portable device which records coordinate information for real world features. For example, one can record the latitude and longitude of a municipal fire hydrant, hiking trail, or wetland. Additionally, the device has the capability to record non-spatial data for each recorded spatial feature. For example, the GPS can record the location of historic structures and offers the option to record its name, street address, and current owner. All non-spatial attributes can be collected simultaneously with the capture of feature coordinates.
NCD owns a Trimble Geo Explorer 2005 Series Geo XM handheld GPS device. This unit is an integrated high-performance 6 channel GPS receiver and antenna capable of 1-3 meter accuracy after differential correction. The unit can track up to eight satellites at once and is capable of recording points (e.g., location of landmarks, trees), lines (e.g., bicycle paths, hiking trails), and areas (e.g., old growth forest stands, agricultural fields). Additionally, we have an antenna for automobile collection applications.
Our GIS Center can assist local officials to record the true location of facilities or natural features that may be required by state or federal programs. Typical work tasks include the establishment of a data dictionary (required for data collection), feature coordinate capture, value added collection, data transfer from the GPS unit to the computer, differential correction, post-processing, export to a GIS format for use with other spatial data, and a hardcopy map showing the collected GPS data.
Please call our office for any questions you may have about our GPS data collection capabilities and costs. You may also email the GIS Center as well.

United States Department of Agriculture Natural Resources Conservation Service (NRCS):
Visit the Web Soil Survey (WSS) for online soil information about your location. This site provides soil data and information produced by the National Cooperative Soil Survey. It is operated by the USDA Natural Resources Conservation Service (NRCS) and provides access to the largest natural resource information system in the world. NRCS has soil maps and data available online for more than 95 percent of the nation’s counties and anticipates having 100 percent in the near future. The site is updated and maintained online as an authoritative source of soil survey information.
