Field Reference Data Acquisition

We use an array of methods to acquire field reference data for clients. One method is Global Positioning Systems (GPS), as it is proven to be a highly accurate and efficient positing technique to acquire geospatial data for many GIS applications.  GPSs allow site data to be acquired directly in the field and then seamlessly exported into a GIS for use in map abstraction and detailed analyses. GPSs not only provide the capability to acquire sub-meter or sub-centimeter accurate location data, GPSs also can be used to record valuable descriptive attributes about any object in any given area of interest. 

At times, GPS acquisition of positional information can be sensitive to procedural variations, environmental factors (e.g., multi-path disturbance from tree canopy), and receiver quality.  Nevertheless, GPSs provide clients with a lower cost alternative by requiring less time and labor to produce a higher output than traditional field surveying methods.

In addition to GPS, we use photo-interpretation, aerial reconnaissance, historical surveys, maps, engineering plans, drawings, topographs, photos, satellite imagery, digital ortho-photos, atmospheric and meteorological reports, leading-edge sensors, as well as numerous ancillary data sources developed by other agencies, or whatever means necessary to conduct ground-based field verification and accuracy assessment.
