Once the data acquisition has been completed, the sounding can, if needed, be filtered and corrected using the built-in sounding editor. From the corrected sounding, a digital terrain model (DTM) can be generated.
By comparing the generated DTM with a theoretical DTM, or a DTM created from a previous sounding, a volume calculation can be performed. For instance, to prove that dredging work has been done correctly.
The software supports multiple map formats, including some nautical map formats, such as S57 ENC and GIS formats like GeoTIFF, ESRI Shape and MapInfo TAB/MIF files. CAD drawings generated with either Microstation or AutoCAD (DXF) can also be used.
The software is shipped with more then 5000 built-in local map projections, which allows you to use it at almost any place on earth.
