GeoVisionary allows for digitisation in 3D space, enabling geologists to digitise geological features directly on the 3-D elevation model and orthophotography. This preliminary mapping capability saves much time especially because it improves the agreement of resultant geologic lines with the topographic base that is used for mapping. GeoVisionary has been designed in such an open way, using XML formats, that other software, such as ESRI, links into it easily. Links to other software packages include individual georeferenced and non georeferenced image files, GeoTIFF images, JPG images, TGA images, SRTM data, most formats of GOCAD, GSI3D — GXML, LiDAR point cloud data surface or points and Enhanced Compression Wavelets.
