United Consulting offers GPS (Global Positioning System) mapping services to provide better accuracy in locating site features. This mapping can be used to locate streams, wetlands, bore holes, monitoring wells, trash piles, and other important features identified on a site.
Equipment
United Consulting owns two GPS units capable of sub-meter mapping accuracy. Our Trimble GeoXT can provide real-time sub-meter mapping accuracy with typical accuracies of ranging from 1.5 to 3 feet. Our Trimble GeoXH mapping units use H-Star Technology to provide sub-foot corrected mapping accuracy. Mapping accuracy of the GeoXH is more variable and is dependent on tree cover, but can provide accuracy of 0.3 foot. Data from these units can be downloaded to a computer, and exported as either a CAD, GIS, or text file.
Saves Time
United Consulting typically uses its GPS equipment to provide timely and accurate mapping of wetland and stream systems. This mapping typically saves time and money over conventional survey methods. We can normally provide a map of our findings within 1-2 days following completion of the field work, versus 2 weeks or more for a typical survey crew. The field data is downloaded, exported as a CAD file, and then over-laid onto the survey provided by the client.
Limitations
As with any GPS system, there are some limitations. The GPS is a mapping quality system and does not replace conventional surveying when survey quality accuracy is required.
