8 months ago The 'Sources for editing' section updated with the below information-
- Removed Maxar Premium Imagery from the list as it's not available anymore in OSM
- Added a description of proprietary sources to support editing
Project description
Goal
To improve the map quality in Saudi Arabia, we propose to make data improvements by sharing challenges that can help fix data errors, and add certain kinds of features.
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 Saudi Arabia Wikipage while you are editing.

- [This multipolygon is a simple polygon](https://maproulette.org/browse/challenges/30120) 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. - [Spiky buildings](https://maproulette.org/browse/challenges/30126) Buildings with extremely sharp angles will be identified and corrected if needed. - [Fix inconsistent highway intersection](https://maproulette.org/browse/challenges/39251) Identify and fix cases where highways intersect without a common node. - [Fix Building and Highway Intersections](https://maproulette.org/browse/challenges/39745) Identify and fix, if needed, cases where a way with tag highway=* intersects with a building. - [Fix Building and Water Intersections](https://maproulette.org/browse/challenges/41818) Identify and fix, if needed, situations where a water feature intersects with a building. - [Fix Incorrect Highway Junctions](https://maproulette.org/browse/challenges/42157) Identify and fix if needed, cases where highway junctions are incorrectly or imprecisely mapped.Missing Roads challenges

- [Missing Highways - Q4 - Riyadh](https://maproulette.org/browse/challenges/37120) - [Missing Roads](https://maproulette.org/browse/challenges/21835) Data analysis done by TomTom suggests that there should be a road or track here in OSM, but it is missing."Skipped" and "Too Hard" cases (Missing Roads)

tomtom is sharing the "Skipped" and "Too Hard" cases that were not solved in our MapRoulette challenges, for the Saudi Arabia community to solve using their local intelligence and knowledge, files can be found here: [Saudi Arabia - skipped and too hard elements.zip](https://github.com/tomtom-international/open-data/files/10105199/Saudi.Arabia.-.skipped.and.too.hard.elements.zip) It was shared with the Saudi Arabia OSM community on a [telegram message](https://t.me/OSMSaudi/6019)Missing Building challenges

- [Dammam](https://maproulette.org/browse/challenges/37106) - [Jeddah - Al-Balad (center area)](https://maproulette.org/browse/challenges/36804) - [Jeddah - Al-Balad (residential area)](https://maproulette.org/browse/challenges/36805) The tasks in this challenge focus on physical structures such as residential, commercial, and industrial buildings, the Missing buildings were detected after a spatial comparison with TomTom's map database, the mappers can use the most appropriate imagery and local knowledge to investigate the situation, Identify and add if needed, one or more missing buildings.Isolated Highways challenges
Click to expand.
- [Connect Isolated Highways](https://maproulette.org/browse/challenges/36812) - [Connect Isolated Highways](https://maproulette.org/browse/challenges/38027) Identify cases where the end of the way (highway) is not connected to another way (highway), the Missing highways were detected after a spatial comparison with TomTom's map database. The mappers can use the most appropriate imagery and local knowledge to investigate the situation, and add the missing highway if they can confirm its existence.Missing Highway Surface
Click to expand.
- [Add Surface to Highway](https://maproulette.org/browse/challenges/37481) The goal of this challenge is to identify and add missing surface tags on a road network. We queried OSM for ways with certain highway=* values where the surface tag was missing.Edits based on User Feedback

TomTom organised editing
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.
How to find TomTom's edits
All edits made by our team have the hashtag #tt or #tomtom.
Sources for editing
For some OSM map edits TomTom editors will use proprietary sources for support. These will typically be in situations where there is not sufficient evidence using the available sources in OSM editors themselves. The proprietary sources will be ground-level imagery and GPS traces, both collected by TomTom's mobile mapping vans. On occasion, we will also use sources collected from a field survey by one of TomTom's sourcing specialists who have visited the location and collected data to support the required map updates.
