PurVIEW’s 3D stereoscope display fuses the image and elevation data of GeoSAR’s two radar bands, enabling the visualization of geodata in three dimensions from multiple editing viewpoints. Significantly, PurVIEW can display in real time GeoSAR’s X-band surface, and P-band surface and subsurface layers draped over a GeoSAR DEM, which greatly improves radar interpretation. Additionally, vector data and other features can also be displayed simultaneously with radar data.
2. TOPOGRAPHIC MAP PRODUCTION
Obtaining consistent, comprehensive TLM datasets can be an arduous task; traditional map production technologies and common GIS practices can comprise hundreds of steps that require multiple data type conversions. ESRI ArcGIS Desktop with PurVIEW streamlines this process, enabling the stereo viewing and feature extraction of GeoSAR TLM data from directly within a 3D environment. Using PurVIEW to view stereoscopic GeoSAR TLM data models means that Fugro EarthData’s analysts are able to efficiently capture and attribute linework and polygons directly to an industry standard geodatabase—greatly expediting the production of large-area topographic maps.
