Prediction Models and Their Pre-Processed Database Files
Depending on the selected mode for the pre-processing run, different output files are generated. The different modes (and thus output files) are required for the different prediction models. All files produced during the pre-processing are stored in binary format.
For each mode, one different file is generated. This file contains the building data as well as the visibility information and the considered parameters for this reprocessing, for example, area, resolution.
The building data of the whole area covered by the ODB file is checked and saved to the corresponding pre-processing file in any case, even when creating database files for IRT prediction. This is because WinProp allows a post-processing of the prediction using the empirical vertical plane models. Therefore, the building information of the whole area is required for any prediction and thus always computed.
While the pre-processing for the empirical vertical plane models (for example, COST) contains always the full area (due to the point mentioned above), the area for the IRT pre-processing can be selected by the user.
Extension | Result File Type |
---|---|
OCB + IDB |
“Outdoor COST Binary” database plus “Indoor Database Binary” database. Pre-processed database for a prediction with the empirical vertical plane models (allowing urban→indoor as well as indoor→urban transitions). |
OIB + IDI |
“Outdoor IRT Binary” database plus “Indoor Database IRT” database. Pre-processed database for a prediction with the deterministic IRT (Intelligent Ray Tracing) model (allowing urban→indoor as well as indoor ➔ urban transitions). |
