Project description

Goal

To improve the map quality in Italy, we propose to make data improvements by sharing challenges, and when appropriate, fixing data errors, and adding or editing certain kinds of geometry.

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 take a look at the OSM wiki page IT: Editing Standards and Conventions while you are editing.

Here is the current set of challenges.

Challenges

Quality check challenges

Click to expand. - [Invalid Lane Tag](https://maproulette.org/browse/challenges/27499) 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. - [Not connected highway](https://maproulette.org/browse/challenges/27497) 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/27494) 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/27493) 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/27490) 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/27496) 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/27492) 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/27489) 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/27491) Buildings with extremely sharp angles will be identified and corrected if needed. - [Polygon is not closed](https://maproulette.org/browse/challenges/27515) 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. - [Inconsistent Bridges and Tunnels](https://maproulette.org/browse/challenges/38357) Identify and fix cases where the bridge or tunnel has an incorrect tag. - [Buildings and Highways Conflict](https://maproulette.org/browse/challenges/38738) Identify and fix, if needed, cases where a way with tag highway=* intersects with a building. - [Fix inconsistent highway intersections](https://maproulette.org/browse/challenges/39343) Identify and fix cases where highways intersect without a common node. - [Fix Building and Water Intersections](https://maproulette.org/browse/challenges/39512) Identify and fix, if needed, situations where a water feature intersects with a building. - [Fix Incorrect Highway Junctions](https://maproulette.org/browse/challenges/42391) Identify and fix if needed, cases where highway junctions are incorrectly or imprecisely mapped. - [Check Small Area Features](https://maproulette.org/browse/challenges/43716) This challenge in Italy helps you check area features of different types (various land use, natural, amenity and leisure features) that are smaller than expected for areas of these types. You may need to correct an area’s tagging, adjust its outline, or merge it with other areas. To do so, follow the detailed guidelines in the left-hand instruction panel of each task. - [Fix Spiky Buildings](https://maproulette.org/browse/challenges/44745) Improve the OpenStreetMap data by validating and fixing buildings with suspicious sharp corners.  - [Advanced Map Editing: Correct Too Short Highways](https://maproulette.org/browse/challenges/49005) This collaborative mapping project, introduced by TomTom, aims to improve OpenStreetMap data by reducing the number of short ways on highways, with attention to junctions where they result in incorrect intersections. - [Fix Isolated Pedestrians’ network](https://maproulette.org/browse/challenges/49137) This collaborative mapping project, introduced by TomTom, aims to improve the quality of the pedestrian network in OpenStreetMap, ensuring that users receive clear, safe, and informative walking directions. - [Fix Pedestrians' Areas network - Milano](https://maproulette.org/browse/challenges/49330) This collaborative mapping project, introduced by TomTom, aims to improve the quality of the pedestrian network in OpenStreetMap, ensuring that users receive clear, safe, and informative walking directions.

Missing feature challenges

Click to expand. - [Missing Parks and Green Areas](https://maproulette.org/browse/challenges/28674) Missing parks and green areas were detected after a spatial comparison with TomTom's map database. - [Missing Buildings in Bologna](https://maproulette.org/browse/challenges/28675) Missing buildings were detected in Bologna after a spatial comparison with TomTom's map database. The tasks in this challenge focus on physical structures such as residential, commercial, and industrial buildings. - [Missing Buildings in Verona](https://maproulette.org/browse/challenges/28676) Missing buildings were detected in Verona after a spatial comparison with TomTom's map database. The tasks in this challenge focus on physical structures such as residential, commercial, and industrial buildings. - [Missing Hospital Areas and Clinic Areas](https://maproulette.org/browse/challenges/28694) Missing hospital areas and clinic areas were detected after a spatial comparison with TomTom's map database. They were validated using related nodes wherever present, or other aerial imagery clues like helicopter landing pads, etc. - [Missing Buildings in Genoa](https://maproulette.org/browse/challenges/37089) Missing buildings were detected in Genoa after a spatial comparison with TomTom's map database. The tasks in this challenge focus on physical structures such as residential, commercial, and industrial buildings. - [Missing Buildings in Florence](https://maproulette.org/browse/challenges/37090) Missing buildings were detected in Florence after a spatial comparison with TomTom's map database. The tasks in this challenge focus on physical structures such as residential, commercial, and industrial buildings.

Road network challenges

Click to expand. - [Connect Isolated Highways](https://maproulette.org/browse/challenges/37383) 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 Missing Highways](https://maproulette.org/browse/challenges/37525) Data analysis done by TomTom suggests that there should be a road or track here in OSM, but it is missing. - [Connect Isolated Highways July 2023](https://maproulette.org/browse/challenges/40277) 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 Missing Highways - Milano](https://maproulette.org/browse/challenges/41056) Data analysis done by TomTom suggests that there should be a road or track here in OSM, but it is missing. - [Add Missing Highways - Rome](https://maproulette.org/browse/challenges/41727) Data analysis done by TomTom suggests that there should be a road or track here in OSM, but it is missing. - [Duplicated Nodes having same coordinates](https://maproulette.org/browse/challenges/41845) Identify and fix if needed, cases where duplicated nodes having same location (coordinates) should be merged. It relates to highways mostly, but ways in general (parks, buildings). We improve overall OpenStreetMap (OSM) route network quality by solving real errors in the data by clearly identifying objects junctions for which nodes are used in this case. Ensuring that highway junctions are connected within OSM is crucial for optimized routing. When road elements are disconnected due to duplicated (not merged) nodes, it can degrade the navigation experience for routing applications that rely on OSM data, leading to inefficient directions, delays, and potential navigation errors. We found leads based on spatial analysis of OSM data to fetch overlapping nodes. - [Connect Isolated Highways - Aug 2024](https://maproulette.org/browse/challenges/49031) 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 - Rome](https://maproulette.org/browse/challenges/49092) Identify and add if needed, one or more missing ways..

TomTom organized editing

We will follow the Organized Editing Guidelines for this project. TomTom will not make any edits until two weeks after the project announcement. Here is our Organized Editing page, including a list of our editors.

How to find TomTom's edits

All edits made by our team receive the hashtag #tomtom. Edits based on user feedback additionally have the hashtag #tt_mapfeedback.

tt is a hashtag that has been used for TomTom’s edits in the past.

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

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:

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
opk12 commented 10 months ago

The instructions for Italy - Fix Incorrect Highway Junctions are misleading. noexit means that you cannot proceed further, even on foot. So it is fine to have nodes close to each other and without noexit; if a QA tool warns, that's a bug in the QA. Real cases of noexit are relatively rare; in this example (maproulette task), there may be a door nearby, reachable on foot, and this cannot be determined by aerial imagery. So the instructions should clarify that in most cases of noexit, a survey is necessary and the mapping should be left as it is.

k127 commented 10 months ago

Hi @opk12 / ppku, for the sake of transparent argueing, let me link to the OSM changeset discussion we've had earlier this day: https://www.openstreetmap.org/changeset/144569219. IMHO, the OSM wiki definition for noexit=yes is applicable in many cases related to the respective MapReoulette / TomTom challenge. Best, k127

ChiaraAngiolini-tomtom commented 10 months ago

Thanks @opk12 and @k127 for your feedback, really appreciate! We have analyzed problem and, from our side, we will do an update to the challenge description.

k127 commented 10 months ago

What? You mean, for other countries? This issue is for Italy, and I completed the challenge a few days ago.

ChiaraAngiolini-tomtom commented 10 months ago

This challenge has already been done in many countries but we do not have feedback from other communities. The description will of course be general and applied to further/new challenges in other countries.
