OsmGpxPreprocessor

OsmGpxPreprocessor is a tool to preprocess OSM gpx traces. It does following processing: - split trace at trackpoints with long distance to consecutive track point - split trace at trackpoints with high change in elevation to consecutive track point - smooth elevation profile of trace

Ideally, the traces have been imported to the PostgresQL/PostGIS database, using the OsmGpxFilter

Getting started

1. install maven
2. install git
3. clone project $ git clone https://github.com/GIScience/osmgpxpreprocessor
4. go into project directory $ cd osmgpxpreprocessor/
5. if necessary, adjust the properties file in resources/preprocessor.properties
6. run maven $ mvn clean package
7. start application java -jar target/osmgpxpreprocessor-0.1.jar <args>

 -h,--help              displays help
Required Arguments:
 -D,--database          Name of database
 -PW,--password <arg>   Password of DB-User
 -U,--user <arg>        Name of DB-Username


Optional Arguments:
 -H,--host <arg>        Database host <default:localhost>
 -P,--port <arg>        Database port <default:5432>
 -s <arg>               Suffix of output table in database. <default:preprocessed>
