Thematics OpenStreetMap-viewer and editor.

OpenStreetMap is a libre and free online database of geodata which can be edited by everyone and is used by millions of people. However, contributing can be challenging or intimidating to non-technical users. MapComplete is a webapp whose goal is to make it trivial to see and update information on OpenStreetMap. This is achieved by showing only features related to a single topic of interest on the map - from playgrounds, public toilets and bicycle rental places to charging stations and public tap water spots.

MapComplete contains many thematic maps, each built for a certain community of users and use cases. By focusing on a single topic, contributors are not distracted by objects not relevant to them. Furthermore, this allows to show (and ask for) attributes that are highly specialized (e.g. a widget that determines tree species based on pictures) but also to reuse common attributes and elements (such as showing and adding opening hours or pictures). Within this project, performance will be improved and a user interface to create a new topical map will be built, which will allow for more people to contribute on more topics.
