We propose to improve the map quality in Greenland by sharing challenges that can help fix data errors.
How to participate
While our team will also work on them, we welcome anyone to contribute to this project by participating in its MapRoulette challenges. Here is the extended documentation for using MR. Note that sometimes additional instructions are provided within the challenges.

- [Not connected highway](https://maproulette.org/browse/challenges/28230)
Ways with tag highway=* must be connected to the rest of the road network to ensure its continuity, e.g. for route planning. When such a way is not connected to another way with tag highway=*, an error is logged.
- [This multipolygon is a simple polygon](https://maproulette.org/browse/challenges/28224)
Simple areas are mapped in OSM by creating a closed way and tagging it as an area object rather than a line. Relations of the type multipolygon are used to represent complex areas with holes inside or consisting of multiple disjoint areas. A multipolygon relation can have any number of ways in the role outer (the outline) and any number of ways in the role inner (the holes), and these must form valid rings to build a multipolygon. When a relation of the type multipolygon consists of only one member, which is a simple area, an error is logged.
Geographical scope
Data improvements will be made across the whole country.
We will follow the Organised Editing Guidelines for this project. TomTom will not make any edits until two weeks after the project announcement. Here is our Organised Editing page, including a list of our editors.
