1 year 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 Romania, 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 WikiProject Romania while you are editing.
Here is the current set of challenges.
Challenges
Quality check challenges

- [Polygon has self-intersection](https://maproulette.org/browse/challenges/36809) 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 - [Spiky buildings](https://maproulette.org/browse/challenges/36808) Buildings with extremely sharp angles will be identified and corrected if needed. - [Polygon is not closed](https://maproulette.org/browse/challenges/36810) 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 Highway Surface

- [Add Surface to Highway](https://maproulette.org/browse/challenges/37437) 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.Isolated Highways challenges
Click to expand.
- [Romania - Isolated Highway](https://maproulette.org/browse/challenges/38540) 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 Roads challenges
Click to expand.
- [Romania - Add Highways](https://maproulette.org/browse/challenges/39084) Data analysis done by TomTom suggests that there should be a road or track here in OSM, but it is missing.Fix Building/Water & Highway intersections
Click to expand.
- [Romania - Fix Building & Highway intersections](https://maproulette.org/browse/challenges/39815) Identify and fix, if needed, cases where a way with tag highway=* intersects with a building. The fix may be either to correct the building footprint or to correct the route of the highway. Use appropriate available sources to decide on the best action to resolve the conflict. - [Romania - Fix Building and Water Intersections](https://maproulette.org/browse/challenges/40683) Our team has identified these challenges through a spatial comparison of water features and buildings available in OSM. We would greatly appreciate your review and resolution of the tasks involved, which include identifying and fixing situations where a water feature intersects with a building. - [Romania - Fix Intersecting Buildings](https://maproulette.org/browse/challenges/49476) When buildings intersect like this, it can make maps look cluttered and harder to read, which can be confusing. By fixing these overlaps, we’ll help make the map clearer and more accurate.Geometry related challenges

- [Romania - Fix Incorrect Highway Junctions](https://maproulette.org/browse/challenges/42090) 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.Visualisation challenges (e.g. Buildings, Water bodies...etc)
Click to expand.
- [Romania - Mapping Missing Buildings in urban area of Bucharest ](https://t.me/OSMRomania/18448) we have identified areas with missing structures and would like invite you to locate and add these buildings to the map where possible. These structures could be residential, commercial, or other, contributing to an enriched visualization of the country. Your participation in adding features and attributes will significantly enhance the map’s value and content, and give reality guidance and real-feel to map users in general. - [Missing Buildings](https://maproulette.org/browse/challenges/37964) This challenges is primarily focused on missing buildings of all types (residential, commercial, industrial…etc.) to be mapped as highlighted. Our team compared TomTom and OSM data using spatial comparisons including intersections and overlaps indexes, we have detected some areas where buildings are missing in OSM; to increase confidence level, the team compared a sample area and conducted analysis to validate some missing buildings. The missing areas can be added by editing several buildings or individual ones; the choice will depend on reality checks and local knowledge. As you may know, you are required to use the most updated satellite and aerial imageries on the background while editing. - [Romania - Fix Spiky Buildings](https://maproulette.org/browse/challenges/45173) Examine the set of potentially erroneous buildings that we’ve identified. Visit the locations on the map and assess whether the building shapes seem inaccurate.Edits based on map feedback
Click to expand.
We 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 or correcting highways - Adding or correcting link roads - Adding or adjusting bridges, tunnels, layers, or relations - Adding or updating lanes and related properties - Adding or updating traffic signs - Adding or updating access barriers - Adding or updating turn restrictions - 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 - Buildings - Adding buildings - Updating building type - Adjusting building shape - Water - Adding or realigning rivers, streams, and lakes. - Railways - Adding railway tracks - Realigning railway tracks - Adding or adjusting railway infrastructure tags such as bridges, tunnels, level crossings - Ferry lines - Adding ferry lines - Realigning ferry lines - Adding ferry terminals These are incidental edits spread over time starting June 5th, 2023. We follow local guidelines and, if needed, consult with the community before making an update.Geographical scope
Data improvements will be made across the whole country.
Announcements
This project was announced in:
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 , #tomtom or #tt_mapfeedback
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.
