To improve the map quality in Malta, we propose to make data improvements by sharing challenges that can help fix data errors, and add or edit certain kinds of geometry.
When appropriate, our team will also work on these challenges. If a challenge is more suitable to be solved without organised help, we will leave it for local users interested in completing the tasks. Challenges like this will be indicated as such in the overview below.
How to participate
Anyone is welcome to contribute to this project by participating in our MapRoulette challenges. Here is the extended documentation for using MR. Note that sometimes additional instructions are provided within the challenges. We also strongly encourage you to make use of the resources listed in the OSM wiki section while you are editing.

- [Not connected highway](https://maproulette.org/browse/challenges/28325)
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.
- [Tag area=yes on object without feature type](https://maproulette.org/browse/challenges/28326)
The area=yes tag is required for some closed ways when used to define a polygon. For closed ways with other tags, there is an assumption that the way defines an area. In some circumstances, a closed way may define both a closed polyline and an area. When tag area=yes is used, it is expected that one of the necessary accompanying tags is also found.
- [Impossible angle in a highway](https://maproulette.org/browse/challenges/28337)
In general, roads intended for vehicles should be built to maintain proper angles which ensure maneuvers and fluent traffic. Extreme, too sharp angles applied to a way may indicate errors in the road geometry.
- [Invalid Turn Restriction](https://maproulette.org/browse/challenges/28322)
This check identifies invalid turn restrictions. Invalid turn restrictions occur in a variety of ways, from invalid members to edge geometry issues to not being routable to wrong topology. Relations, ways and nodes in relations as well as turn restrictions are checked. A relation needs to have exactly one way with role 'from' and exactly one way with role 'to'. These ways should be linked together by at least one way with role 'via' OR with exactly one node with role 'via' (no more and no less).
- [Multipolygon is a simple polygon](https://maproulette.org/browse/challenges/30111)
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.
- [Buildings and Highways Conflict](https://maproulette.org/browse/challenges/39342)
Identify and fix, if needed, cases where a way with tag highway=* intersects with a building
- [Fix Intersecting Buildings](https://maproulette.org/browse/challenges/41018)
Identify and fix, if needed, situations where a building intersects with another building at the same layer.
- [Fix Incorrect Junctions on Roundabouts](https://maproulette.org/browse/challenges/42106)
Identify and fix cases where two or more highways are connected to the same node on a roundabout.
- [Fix deprecated landuse reservoir tag](https://maproulette.org/browse/challenges/43724)
Update the deprecated tag landuse=reservoir on water reservoirs in Malta.

- [Connect Isolated Highways](https://maproulette.org/browse/challenges/39531)
Identify and connect if needed cases where the end of the way with tag highway=* is not connected to the rest of the road network.
- [Add Highways](https://maproulette.org/browse/challenges/41646)
Data analysis done by TomTom suggests that there should be a road or track here in OSM, but it is missing.

Mapping Buildings: Locate and add missing buildings, which may be residential, commercial, or other structures. Review the imagery layer to ensure existing buildings are accurately represented..
Geographical scope
Data improvements will be made across the whole country.
Announcements
This project was announced in talk-it mailing list as there was no direct communications with the Maltese OSM community. Kindly refer to the project leads for recommendations.
The new addition was done at this location: WikiProject_Malta Section: _MapRoulette Challenge: This multipolygon is a simple polygon (tomtom, 23 November 2022)
Due to lack of community and channel of communication, from May 2023 the announcement for Malta have been sent directly to Maltese user mikefalzon.
TomTom organised editing
