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 Australia, 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 Australia OSM wiki while you are editing.
Here is the current set of challenges.

-[This multipolygon is a simple polygon](https://maproulette.org/browse/challenges/30106) 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/30104) Buildings with extremely sharp angles will be identified and corrected if needed. -[Polygon is not closed](https://maproulette.org/browse/challenges/30105) Features intended to be a polygon should be correctly tagged. When the tag indicates that the object should be a polygon, but the geometry is built out of a NON-closed way, an error is logged. -[Polygon has self-intersection](https://maproulette.org/browse/challenges/36470) The necessary edits will be made to fix cases where the tag on a way indicates that the object is a polygon feature, but the way does not meet the definition of a closed way because it is self-intersecting, or ways in relation with the same role form a self-intersecting polygon -[Australia - Fix Inconsistent Highway Intersections](https://maproulette.org/browse/challenges/40074) We used a modified version of Osmose check 1250 – objects intersection, with certain situations, such as pedestrian paths, removed from the scope. The objective is to identify and fix cases where highways intersect without a common node. -[Australia - Fix objects without tags](https://maproulette.org/browse/challenges/44303) This collaborative mapping project, aims to enhance OSM data by addressing and fixing objects without tags, which may include duplicates, mapping errors, nonexistent objects, and unintended edits. This project was designed to improve the accuracy and completeness of OpenStreetMap data by identifying and addressing objects without proper tags. -[Australia - Fix Spiky Buildings](https://maproulette.org/browse/challenges/44774) To review and correct potentially erroneous building geometries to enhance data quality and accuracy.Geometry and Missing feature challenges

-[Missing Highways - Q4 - Melbourne](https://maproulette.org/browse/challenges/37136) -[Missing Highways - Sydney](https://maproulette.org/browse/challenges/30107) -[Missing Highways - Victoria](https://maproulette.org/browse/challenges/37398) -[Australia - Add Missing Highways - Jan 2023 - Victoria](https://maproulette.org/browse/challenges/37398) -[Australia - Add Highways](https://maproulette.org/browse/challenges/37638) -[Australia - Add Highways - New South Wales](https://maproulette.org/browse/challenges/38451) -[Australia - Add Missing Buildings - Melbourne - Albert Park](https://tasks.openstreetmap.us/projects/534) Data analysis done by TomTom suggests that there should be a road or track here in OSM, but it is missing.Missing Water features challenges
Click to expand.
-[Australia - Add Water Features](https://maproulette.org/browse/challenges/39969) We have identified potential leads by comparing water features in OpenStreetMap (OSM) with TomTom’s map database. The challenge focuses on various types of water features, including small ponds and puddles.Isolated Highways challenges
Click to expand.
-[Australia - Connect Isolated Highways - Q4](https://maproulette.org/browse/challenges/36803) -[Australia - Isolated Highways - Queensland](https://maproulette.org/browse/challenges/38442) Leads are generated based on analysis of highway classifications and their connection to the rest of the road network, you can 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.Intersecting feature challenges
Click to expand.
-[Australia - Fix Building and Highway Intersections](https://maproulette.org/browse/challenges/40063) We conducted spatial analysis and discovered instances where a highway and building feature intersects. The objective of this challenge is to identify and rectify the building and/or Highway using reliable sources to ensure accurate map and data representation -[Australia - Fix Inconsistent Highway Intersections](https://maproulette.org/browse/challenges/40074) We used a modified version of Osmose check 1250 – objects intersection, with certain situations, such as pedestrian paths, removed from the scope. The objective is to identify and fix cases where highways intersect without a common node. -[Australia - Fix Intersecting Buildings](https://maproulette.org/browse/challenges/42349) Identify and fix, if needed, situations where a building intersects with another building at the same layer. -[Australia - Fix Building and Water Intersections](https://maproulette.org/browse/challenges/42564) We did a spatial comparison of water features and buildings available in OSM. The goal is to identify and fix, if needed, situations where a water feature intersects with a building.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
-Esri World Imagery -Bing Maps Aerial -Please follow the Australian community instructions on Data Sources
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.
How to reach out
If you have remarks about a specific edit of ours, please drop a comment in the changeset, and we will do our best to respond thoughtfully. Or, you can also:
-send a message to the project lead Kiran Ahire, -join the conversation in Oceania OSM Discord,Talk-au Mailing List -email kiran.ahire@tomtom.com for general questions about TomTom's activities.
