UAV Mapping Services
As a new method of raster data collection, UAV survey technology effectively complements existing techniques, fitting between large-area satellite/manned aircraft imagery and smaller coverage, time-consuming terrestrial approaches. Using industry leading technology, SDI is able to provide high-resolution 3D point clouds, surface models, and orthomosaic imagery for projects with different scales. Survey results can be integrated into SDI’s acoustic bathymetric and subbottom survey results and are compatible with mainstream GIS and CAD software packages.
