The paper is focused on developing a new approach how automatically process 3D geospatial data for Remcom Wireless InSite. Remcom Wireless InSite is a software tool which provides efficient and accurate predictions of an electromagnetic waves propagation and a communication channel characteristics in complex urban, indoor, rural and mixed path environments. The Wireless InSite is able to import a 3D geospatial model, that consists of a DTM (Digital Terrain Model) and objects (buildings). To be able to perform any predictions, we need to import different geodata objects into Wireless InSite and run calculations in an automated way. We tested several available functions for importing geodata to Wireless InSite. All of them have some drawbacks that made us do free import/export tool that reads data from 3D GIS (Geographic Information System) database and exports them to the form that can be directly read by Wireless InSite. The main advantage of this approach is complete control over the import and export processes. For example, we can specify the LOD (Level of Detail) for import, or we can specify for each different object the type of material. |
