你好。 我是來自 TomTom 的 Syed，如果這條使用在線翻譯器創建的消息有任何錯誤，我提前道歉。
我想分享一個新的 MapRoulette 挑戰，您可能會感興趣。 這個挑戰可以幫助您分析台灣似乎與網絡其餘部分未連接的道路，並在需要時解決問題：https://maproulette.org/browse/challenges/39269
例子:
感興趣的地圖製作者，請隨時使用可用圖像、當地知識和 MapRoulette 中提供的說明來完成這 209 項任務中的任何一項。
請分享有關此挑戰或您感興趣的任何其他領域的寶貴反饋。 另外，讓我知道是否有一個溝通渠道可以接觸到更多有共同興趣改進台灣地圖的社區成員。

# Project description
## Goal
Improving the map quality in Taiwan 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 [common tagging methods](https://wiki.openstreetmap.org/wiki/Zh-hant:Map_Features) for Taiwan.
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/52480).
## Challenges
### Quality check challenges
Click to expand.
- [Invalid Lane Tag](https://maproulette.org/browse/challenges/23778)
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/23771)
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/23774)
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/23776)
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/23779)
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/23769)
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/23773)
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/23775)
Buildings with extremely sharp angles will be identified and corrected if needed.
- [Polygon is not closed](https://maproulette.org/browse/challenges/23768)
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.
### Isolated Highways Challenges
These are tasks comprising of situations when a way with tag highway=* is not connected to the rest of the road network. Analyze and, if needed, connect the way to another way with tag highway=*.

- [Taiwan - Connect Isolated Highways](https://maproulette.org/browse/challenges/39269)
## Geographical scope
Data improvements will be made across the whole country.
## Announcements
- Announced the Isolated Highways challenge on 09-May-23 in the [TWN OSM community forum](https://community.openstreetmap.org/c/communities/tw/42).
- This project was announced in the [Talk-TW mailing list](https://lists.openstreetmap.org/pipermail/talk-tw/2021-December/001491.html).
## TomTom organised editing
We will follow the [Organised Editing Guidelines](https://wiki.osmfoundation.org/wiki/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](https://wiki.openstreetmap.org/wiki/Organised_Editing/Activities/TomTom), including a list of our editors.

我期待著您的回音。 快樂的映射。
Hello. I am Syed from TomTom.
I’m reaching out to share a new MapRoulette challenge that could be of your interest. This challenge can help you analyze roads in Taiwan that appear to be unconnected from the rest of the network and fix the situations if needed:https://maproulette.org/browse/challenges/39269
Example:
Interested mappers, please feel free to work on any of these 209 tasks using available imagery, local knowledge, and the instructions provided in MapRoulette.
Please share your valuable feedback concerning this challenge or any other areas of your interest. Also, let me know if there is a communication channel where I can reach out to more community members sharing the common interest of improving the Taiwan map.
