Project description

Goal

Improving the map quality in Indonesia by sharing tasks that can help fix data errors and/or add certain kinds of features.

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 follow good practices, editing standards, and tagging conventions for Indonesia.

Here is the current set of challenges.

Active Challenges

Fix Intersecting Buildings

Identify and fix, if needed, situations where a building intersects with another building at the same layer.

Fix Building and Highway Intersections

Identify and fix, if needed, cases where a way intersects with a building.

Fix Inconsistent Highway Intersections

Identify and fix cases where highways intersect without a common node.

Fix Inconsistent Bridge and Tunnel Tagging

Identify and fix cases where the bridge or tunnel has an incorrect tag.

Add Highways

Identify and add if needed, one or more missing ways. We spatially compared TomTom's in-house road centerlines with the OSM road network and identified missing way locations.

Inactive Challenges

Click to expand. ### Connect Isolated Highways - [Not connected highway](https://maproulette.org/browse/challenges/27824) ### Add Surface to Highway - [Indonesia - Add Surface to Highway](https://maproulette.org/browse/challenges/38235) - [Indonesia - Add Surface to Highway - Jan 2023](https://maproulette.org/browse/challenges/37472) Identify and add missing surface tags on a road network. ### Other Quality Check Challenges - [Invalid Lane Tag](https://maproulette.org/browse/challenges/27828) The tag lanes=* on ways with tag highway=* indicates the amount of lanes on the road at hand. The value for the lanes tag should be only one of the following numbers: 1, 1.5, 2, 3, 4, 5, 6, 7, 8, 9, 10. Any other value is incorrect and should be fixed. - [Tag area=yes on object without feature type](https://maproulette.org/browse/challenges/27826) 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/27825) 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/27829) 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). - [Invalid Mini-Roundabout](https://maproulette.org/browse/challenges/27833) Mini-roundabouts are a special kind of roundabout with the same rules as other roundabouts, but present as painted circles rather than physical circles. There might also be a low, fully traversable dome or island that vehicles can drive across. Road traffic flows in one direction around a point in the middle, and the traffic in the roundabout has right-of-way. A mini-roundabout is recorded using the tag highway=mini_roundabout. - [Polygon has self-intersection](https://maproulette.org/browse/challenges/27827) 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 a relation with the same role form a self-intersecting polygon - [This multipolygon is a simple polygon](https://maproulette.org/browse/challenges/27822) 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/27823) Buildings with extremely sharp angles will be identified and corrected if needed. - [Polygon is not closed](https://maproulette.org/browse/challenges/27830) 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.

Edits based on Map Feedback

We will make improvements to OSM based on user feedback submitted for the TomTom map after comparing and ensuring that it is also valid for OSM. Here is a list of the types of edits that could be made, provided they do not conflict with others’ edits and a local source is available: - Highways - Adding highways - Realigning highways - Adding or adjusting bridges, tunnels, layers, or relations - Updating lanes - Updating traffic signs - Addresses - Adding or correcting addresses - Updating the position of address nodes, usually when an object has multiple addresses - Adding or correcting names of ways - POIs (Points of Interest) - Adding POIs - Correcting POI locations - Adding or correcting POI information - Resolving POI-land use discrepancies - Handling POI closures - Land Use - Adding land use - Modifying existing land use extent - Adjusting building shape - Buildings - Adding buildings - Updating building type - Adjusting building shape - Water - Adding or realigning rivers, streams, and lakes.

Geographical scope

Data improvements will be made across the whole country.

Announcements

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.

How to reach out

The 'Sources for editing' section updated with the below information-

  1. Removed Maxar Premium Imagery from the list as it's not available anymore in OSM
  2. Added a description of proprietary sources to support editing
