Scenario 1 “Explore OSM data on-site”
OSMapTuner may be used by any person to explore OSM data on-site (users do not have to be registered with OSM). Simply take an Android-based smartphone or tablet PC, load OSMapTuner from the Android Market, go to the site and start OSMapTuner. Since OSMapTuner works with location-based data, map data in your vicinity will immediately be loaded from the OSM database. With the touch-enabled map view of OSMapTuner it is possible to select arbitrary OSM nodes or ways and get a detailed view of relevant tags and tag values. If you are not familiar with OSM or the tagging scheme proposed in the OSM Wiki, OSMapTuner provides an easy way to get familiar with the map features as well as the tagging scheme. OSMapTuner includes tag pre-sets which directly refer to the definitions in the OSM Wiki. In the OSM Wiki, each tag is linked to the corresponding WIKI page (-button) for easy refernce. If the set of tag values is pre-defined in the OSM Wiki, the values are also available as pre-sets. As long as you are not logged in to the OSM server, you can experiment with OpenStreetMap data and make arbitrary changes. All changes will only be stored locally on your mobile device.
Scenario 2 “Add/edit OSM data on-site”
OSMapTuner may be used by OSMappers to check OSM data on-site and to add or edit tags and/or tag values. Just take your smartphone or tablet PC, start OSMapTuner and select the nodes or ways you want to edit. Since OSMapTuner includes tag pre-sets which directly refer to the definitions in the OSM Wiki, tag editing is very comfortable. OSMapTuner offers pre-sets for tags and tag values with an integrated function for tag validation. In case the tag values are specified in the OSM Wiki, OSMapTuner checks for syntactical correctness (e.g. valid characters or numbers) and in some cases also for semantic correctness (e.g. if tag values are pre-defined in the OSM Wiki). In addition to the pre-defined tags and tag values, you are also free to add “free tags”, which are not specified in the OSM Wiki. When you are done with your editing task, you either have the option to submit your changes directly to the OSM server, or to store your changes on your mobile’s SD card and edit/submit them later via JOSM. Intentionally, OSMapTuner is not designed to edit geometries or to add new nodes, ways or relations. We think that these editing tasks are best accomplished with a desktop editor such as JOSM, and not with a mobile editor such as OSMapTuner.
