JOSM is the editor of choice for editing Openstreetmap data. In this talk we discover all the tweaks that can make contributing data much more convenient. Are there combinations of tags you use all the time? Add them as a preset, which can be applied to the selected objects by a simple press of a button on the taskbar. JOSM comes with a plethora of plugins to increase functionality. We explore which make sense to install and how to use them. Openstreetmap data is a rich dataset. Contrary to conventional GIS systems, all data is squashed together though. One way to find what’s relevant for your area of interest or the the type of routes you’re editing, is by using filters to hide some of it from view. MAPCSS is another way to highlight the data you want to be working with. A recent addition to JOSM is the ability to compose names from tags of the objects themselves or from the relations they are members of. A little side step to Overpass API, which enables only downloading that subset of the data you want to work with. For example a skeleton of ways of a walking, cycling or public transport network. If time permits we can also have a look at how to script JOSM in Python.


Jo Decock is a network administrator who tries to give back to the free software world by contributing data to Wiktionary and Openstreetmap. He has a passion in search for the limits of the possibilities of the free software tools available. He has been working with PostgreSQL for a few years now. Unsurprisingly he found the way to PostGIS and more recently to QGIS to visualise geometries and help with data conversion.
