Hi everyone!
David from TomTom. Happy August!
We are launching a new Map Roulette (MR) challenge in ISR in regard to Isolated Highways that should be connected (“Connect Isolated Highways”). This MR challenge should help you discover some quality issues on OSM map.
You will find 29 tasks on in this challenge: MapRoulette
You can find more details about TomTom’s data improvement activities in Israel on our Github page:

# Project description
## Goal
Improving the map quality in Israel by sharing t… asks 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](https://learn.maproulette.org/documentation) for using MapRoulette. Note that sometimes additional instructions are provided within the challenges. We also strongly encourage you to follow the [OSM editing good practices](https://wiki.openstreetmap.org/wiki/Good_practice) and adhere to the [Israel conventions and guidelines](https://wiki.openstreetmap.org/wiki/Israel#Conventions_and_guidelines).
When appropriate, TomTom will also work on the tasks. If they are more suited to be solved without organized help, we will indicate as such in the overview and leave them for interested mappers with local knowledge to complete the tasks.
Here is the current [set of challenges](https://maproulette.org/browse/projects/48947).
## Challenges
### Missing Buildings
<details>
<summary>Click to expand.</summary>
Identify 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. The tasks in this challenge focus on physical structures such as residential, commercial, and industrial buildings.

### Quality check challenges
<details>
<summary>Click to expand.</summary>
- [Israel - Add Surface to Highway - Jan 2023](https://maproulette.org/browse/challenges/37473)
Identify and add missing surface tags on motorways and motorway links.
- [Tag area=yes on object without feature type](https://maproulette.org/browse/challenges/28327 )
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/28328 )
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/28338)
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).
- [Polygon has self-intersection](https://maproulette.org/browse/challenges/28339)
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/28324 )
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 is not closed](https://maproulette.org/browse/challenges/28335)
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.
- [Add parks and green areas](https://maproulette.org/browse/challenges/38329)
Add missing parks or green areas if you can confirm their existence after analyzing the leads in this challenge.
- [Buildings and Highways Conflict](https://maproulette.org/browse/challenges/39253)
Identify and fix, if needed, cases where a way with tag highway=* intersects with a building.
</details>
### Isolated Highways Challenges
<details>
<summary>Click to expand</summary>
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.
- [Not connected highway](https://maproulette.org/browse/challenges/28329)
</details>
### Missing Highways Challenges
<details>
<summary>Click to expand.</summary>
Data analysis done by TomTom suggests that there should be a road or track here in OSM, but it is missing.

## Edits based on map feedback
<details>
<summary>Click to expand.</summary>
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 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
- Buildings
- Adding buildings
- Updating building type
- Adjusting building shape
- Water
- Adding or realigning rivers, streams, and lakes.
These are incidental edits spread over time starting June 9, 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.

I hope this MR challenges will serve you on the disconnected roads topic. Please let me know if you have any questions or specific mapping interests or specific quality issues.
