Digital Concrete Imaging provides ground penetrating radar (GPR), electromagnetic (EM), and electronic detection services. These technologies can locate utility location to sinkhole detection. These technologies can also provide environmental surveys and locate obstructions in concrete. GPR data can be captured in a 3D data set by setting up a grid pattern for X,Y and Z coordinates. 3D applications are can be used for graveyards, debris fields, post-tension slabs, utility locating and many others. Basic GPS mapping for sub-meter accuracy can be completed using the GSSI SIR-3000 control unit and Trimble's AG114 antenna. The data is then integrated in the GPR data and positions can be found quickly in post processed data. Advanced GPS is provided in either sub-foot or centimeter accuracy. DCI provides sub-foot accuracy on any jobsite and centimeter accuracy in select areas. Data can be provided in Google Earth, CAD drawings in existing files or DCI created ones.
