Mapping and GIS

Field GIS Data Collection

SME GIS staff is experienced in workflows to achieve highly accurate field GIS data. Equipped with Trimble Geo XH Explorer 2008 handheld GNSS units with H-Star Technology and TerraSync field GIS data collection software, SME accurately and efficiently collects data while in the field.  GIS data is post processed using Trimble GPS Pathfinder Office to ensure at least submeter horizontal accuracy. In difficult environments such as below canopy or in canyons, SME utilizes the Trimble Hurricane external antenna, making sub-foot horizontal and vertical accuracy possible. This equipment is for mapping grade products and provides a cost effective and efficient method for data collection when survey grade accuracy is not required.
