OsmGpxInclinecalculator is a tool to calculate incline information from GPX traces. It requires the GPS data as 3D-Linestrings, a street network and a table relates the GPS traces to the street network (which trace was recorded on which street segment). Following tools may be used for importing, preprocessing and map matching:
- Importing and filtering by Bbox and elevation attribute: OsmGpxFilter
- Preprocessing of GPS traces (smoothing of elevation): OsmGpxPreprocessor
- MapMatching (requires street network): OsmGpxMapMatcher
The individual names of the database table and the column names can be adjusted in the properties file which is located under resources.
With the tool it is also possible to calculate the incline from a DEM in geotif format (such as SRTM), which is used to evaluate the incline calculated from GPS traces. The path to the geotiff file has to be set in the properties file. If no evaluation is desired just leave the parameter blank or comment it.
