台灣社區大家好,
我是 TomTom 的 Syed。 一如既往,我對機器翻譯消息中的任何錯誤表示歉意。
在努力改進 OSM 的過程中,我們計劃根據用戶輸入進行編輯。 此活動是檢查收到的 TomTom 地圖反饋是否也對 OSM 有效的結果。
請注意,從少量開始,我們只會在以下情況下執行編輯:
• 為OSM 地圖增加價值
• 不與社區最近所做的任何編輯相衝突
• 得到本地資源的支持。
在缺乏可靠來源材料的情況下,我們將向您(當地社區)尋求指導。
在此活動中,我們將從編輯 POI、土地用途、地址和高速公路開始。 隨著時間的推移,我們將評估更多反饋並擴展到其他功能。 您可以參考 GitHub,了解有關計劃編輯類型以及 TomTom 在台灣的其他活動的更多詳細信息:

# 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).
## Active Challenges
### Fix Building & Highway Intersections
Identify and fix, if needed, cases where a way with tag highway=* intersects with a building.
- [Taiwan - Fix Building & Highway intersections](https://maproulette.org/browse/challenges/39412)
### Road network challenges
Identify and add if needed, one or more missing ways.
- [Taiwan - Add Highways](https://maproulette.org/browse/challenges/39430)
## Inactive Challenges
### Isolated Highways Challenges
<details>
<summary>Click to expand</summary>
- [Taiwan - Connect Isolated Highways](https://maproulette.org/browse/challenges/39269)
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=*.
</details>
### Quality check challenges
<details>
<summary>Click to expand.</summary>
- [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.

## Geographical scope
Data improvements will be made across the whole country.

## 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.
### How to find TomTom's edits
All edits made by our team have the hashtag #tt or #tomtom.
## Sources for editing
- Maxar
- Esri
- Bing
## 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:
- send a message to the project lead [Syed](https://www.openstreetmap.org/user/Syed_N),
- join the conversation in the [Taiwan community forum](https://community.openstreetmap.org/t/challenge-to-improve-highways-intersecting-buildings/100799),
- email [osm@tomtom.com](mailto:osm@tomtom.com).
用於這些編輯的 MapRoulette 挑戰只有我們的編輯團隊才能訪問,因為它可能包含機密信息。 除了 OSM 中每次 TomTom 編輯都附帶的 tomtom 標籤之外,如果是根據用戶反饋進行的編輯,我們還會將 #tt_mapfeedback 添加到變更集中。
我們計劃兩週後從台灣開始。 如果您有任何想法或疑問,請與我聯繫。
祝你今天過得愉快。
Hello Taiwan community,
I am Syed from TomTom. In our endeavor to improve OSM, we plan to conduct edits based on user input. This activity is the result of checking if feedback received for the TomTom map is also valid for OSM.
Note that, starting with a small number, we will only perform edits if they:
• add value to the OSM map
• do not conflict with any recent edits made by the community
• are supported by a local source.
In the absence of credible source material, we will reach out to you, the local community, for guidance.
We will start with editing POIs, land use, addresses, and highways during this activity. Over time, we will evaluate more feedback and expand to other features. You can refer to the following GitHub issue for further details regarding the types of planned edits as well as TomTom’s other activities in Taiwan:

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.
### How to find TomTom's edits
All edits made by our team have the hashtag #tt or #tomtom.
## Sources for editing
- Maxar
- Esri
- Bing
## 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:
- send a message to the project lead [Syed](https://www.openstreetmap.org/user/Syed_N),

- email [osm@tomtom.com](mailto:osm@tomtom.com).
The MapRoulette challenge used for these edits will be accessible only for our editing team as it could contain confidential information. Along with the tomtom hashtag that accompanies every TomTom edit in OSM, we will also add the #tt_mapfeedback to the changeset if it is an incidental edit resulting from user feedback.
We plan to start with Taiwan after 2 weeks along with a selection of countries for which there is available user input, and then expand to other countries. Please reach out to me if you have thoughts or questions about this upcoming activity or anything else.
Have a nice day.
