Project description

Goal

To improve the map quality in Norway, 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 MapRoulette. Note that sometimes additional instructions are provided within the challenges.

Here is the current set of challenges.

Challenges

Quality check challenges

Click to expand. - [Spiky buildings](https://maproulette.org/browse/challenges/27713) Buildings with extremely sharp angles will be identified and corrected if needed. - [Not connected highway](https://maproulette.org/browse/challenges/27717) 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. - [This multipolygon is a simple polygon](https://maproulette.org/browse/challenges/27715) 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. - [Polygon has self-intersection](https://maproulette.org/browse/challenges/27711) 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 - [Tag area=yes on object without feature type](https://maproulette.org/browse/challenges/27716) 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. - [Invalid Mini-Roundabout](https://maproulette.org/browse/challenges/27719) 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 is not closed](https://maproulette.org/browse/challenges/27718) 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.

Missing Roads (NVDB-OSM)

Click to expand. On the request of the community and user [NKA](https://www.openstreetmap.org/user/NKA), TomTom will support editing a number of missing highways in some municipality. The source used by the Norwegian OSM community in detecting the missing roads is coming from The Norwegian National Road Database (NVDB) compared to OSM, the delta finding can be check [here](https://wiki.openstreetmap.org/wiki/Import/Catalogue/Road_import_(Norway)/Update) * General Capturing Rules * TomTom will work on cities that are more than and equal to 3% of missing road * Follow-up is available under the [link](https://eur02.safelinks.protection.outlook.com/ap/x-59584e83/?url=https%3A%2F%2Ftomtominternational-my.sharepoint.com%2F%3Ax%3A%2Fg%2Fpersonal%2Fsalim_baidoun_tomtom_com%2FEcJ30Qz1E6hFi0jPFplcr7ABzcCqnqz_9QMhzCk8sPxCiQ%3Fe%3Dve7a3T&data=05%7C01%7CSalim.Baidoun%40tomtom.com%7C6d8a363c0c174446a0cf08da6fd6fae4%7C374f80267b544a3ab87d328fa26ec10d%7C0%7C0%7C637945266497970755%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=FMS7a2LhZK3pNrMDthQnO5d59clGJU4nwUrnWBlqgsw%3D&reserved=0) * Wiki page referring to source material and way of working is available under the [link](https://wiki.openstreetmap.org/wiki/Import/Catalogue/Road_import_(Norway)/Update) - Skipped / rejected cases saved in separate .osc file should be stored in within a defined folder and municipality name - Road classification correctness is crucially important (highway, service, tracks), differentiate from tracks (tractors, 4WD…etc.) * Exceptions: * motorway * trunk * primary * secondary * construction * tunnels * All highways to be added should be verified towards Norway Orthophoto: * If the highway to be added cannot be seen on the imagery, skip it. * If a highway to be added is seen on the imagery but it seems to be abandoned (e.g. grass on the road), tag it highway=track. * Live cases: * If the highway is a duplicate, then will be skipped. * If the highway is partly overlapping, only add the part which is new/not already in OSM. * In some cases, the highway in question may already exist in OSM, but it may have a big offset or a very rough geometry. In those cases replace the new existing highway with the new one ("More Tools -> Replace Geometry" menu in JOSM). May need to split the existing way first for the sections to correspond. * If it is difficult to determine what to do, too detailed etc, just skip it. You'll find our team editing missing roads municipalities with "TomTom" added on the comment column in this [table](https://wiki.openstreetmap.org/wiki/Import/Catalogue/Road_import_(Norway)/Update). The project editing support was announced in the [Norway User Forum](https://forum.openstreetmap.org/viewtopic.php?pid=868224#p868224) -[Norway - Add Highways](https://maproulette.org/browse/challenges/43708) The tasks were generated by comparing the NVDB, OpenStreetMap and TomTom datasets. you will find 268 tasks for your kind review after your careful review using reliable sources if needed. the objective is to Identify and add if needed, one or more missing ways.

Highways challenges

Click to expand. -[Norway - Connect Isolated Highways](https://maproulette.org/browse/challenges/37629) 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. -[Norway - Fix Intersecting Buildings](https://maproulette.org/browse/challenges/49165) Identify and fix, if needed, situations where a building intersects with another building at the same layer. We generate the leads after a spatial comparison of buildings available in OSM.

Missing Ferries

Click to expand. Ferry routes that may be absent from the OpenStreetMap in Norway. Our team conducted an analysis using the source (https://vegkart.atlas.vegvesen.no/#kartlag:geodata/@600000,7225000,3). We compared spatial data from this source with OSM data and processed two files containing similar content but in different formats. - Ferries (SHP): https://shared-assets.adobe.com/link/771c2bde-4f85-4a9f-77dd-19d8996a3542 - Ferries (GeoJson): https://shared-assets.adobe.com/link/fb066fa1-8244-49a5-7e26-048d7a5115c6 [ferries.zip](https://github.com/tomtom-international/open-data/files/13392026/ferries.zip) [NorMissingFerryOK.geojson.zip](https://github.com/tomtom-international/open-data/files/13392032/NorMissingFerryOK.geojson.zip)

Edits based on User 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 to 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.

Add Surface to Highways challenges

Click to expand. -[Norway - Add Surface to Highway](https://maproulette.org/browse/challenges/37628) 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.

Missing feature and tag challenges

Click to expand. - [Norway - Fix inconsistent bridge and tunnel tagging](https://maproulette.org/browse/challenges/38459) Identify and fix cases where the bridge or tunnel has an incorrect tag. -[Norway - Fix objects without tags](https://maproulette.org/browse/challenges/43902) This collaborative mapping project, introduced by TomTom, aims to improve the OpenStreetMap data by validating and fixing objects without tags. It is proper tagging that represents good editing practice, while objects without tags are undesirable in OpenStreetMap and should be either fixed by adding missing attributes or removed in case of duplicated or not existing objects

Add or Fix Buildings challenges

Click to expand. - [Norway - Add Buildings](https://maproulette.org/browse/challenges/39823) Focused on physical structures such as residential, commercial, and industrial buildings, by identifying and add if needed, a missing building or building information. In addition to that, you can add smaller buildings in the vicinity if you find them missing on the map. - [Norway - Fix Spiky Buildings](https://maproulette.org/browse/challenges/44791) We’ve identified buildings on OpenStreetMap (OSM) with oddly sharp angles. Most building corners are close to 90 degrees, but this challenge focuses on buildings where angles are less than 15 degrees. While some might be real, many are likely incorrect data.

Fixing intersecting features

Click to expand. - [Norway - Fix Building and Highway Intersections](https://maproulette.org/browse/challenges/40682) Leads are generated based on a spatial comparison of highways and buildings available in the OSM data. Identify and fix, if needed, cases where a way with tag highway=* intersects with a building.

Road Geometry and Junction challenges

Click to expand. - [Norway - Fix Incorrect Highway Junctions](https://maproulette.org/browse/challenges/42087) Identify and fix if needed, cases where highway junctions are incorrectly or imprecisely mapped. We improve overall OpenStreetMap (OSM) route network quality by solving real errors in the data. Ensuring that highway junctions are connected within OSM is crucial for optimized routing. When road elements are disconnected or imprecisely mapped, it can degrade the navigation experience for routing applications that rely on OSM data, leading to inefficient directions, delays, and potential navigation errors.

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

If you have remarks about an edit that we made, please drop a comment in the changeset, and we will do our best to respond as quickly as possible. Or, you can also:
