The OpenStreetMap Taiwan community keep track of major development site, and sometimes discuss tagging scheme of mapping in Taiwan. --- ## Keep track of vandlism of Taiwan and recovery  **easy spotted by QA Tools like Osmcha** ![](https://i.imgur.com/yLDU1uP.jpg =560x) Note: It is quite easy to spot vandlism by varies QA tools --- ## Keep track of vandlism of Taiwan and recovery  ![](https://i.imgur.com/H4baf3c.png =560x) Note: The most annoying stuff is unhappy Chinese people adding notes or claimed China owns Taiwan. --- ## Cross Taiwan Strait Railway planned only by China  ![](https://i.imgur.com/k8tRdw9.png =560x) Note: Sometimes Chinese people are making unrealistic edit, for example, cross Taiwan Strait Railway. It might be possible to add as proposal status, but most editors are not aware about it.

In the early days of Taiwan community, we are not able to clean up our mess by ourself. --- ## 早年合作 ê 例：村里標示  [![](https://i.imgur.com/fs9Ds83.png)](https://overpass-turbo.eu/s/1kR3) Note: Here is the visualization of the whole near 8 thousand villages of Taiwan. --- ## 村里匯入  * 主管機關 tùi 主計總處改 kàu 內政部戶政司 * 村里整併 kah 拆分 * ex: 人口濟 * ū 家私來監控政府端 ê 公告 Note: We found out that some times villages will change. And made things worse is we didn't use the newest village dataset to import. It was dealt with Directorate-General of Budget, Accounting and Statistics, and hand over to Department of Household Registration to take care. And some times local government will merge or split villages. --- ## Network Analysis of administrative units  <div style="display:inline-flex;align-items:center;gap:2rem;"> <div style="flex:1;text-align:left;font-size:100%;left" > ![圖片](https://hackmd.io/_uploads/r1e-qUabR.png =600x) </div> <div style="flex:1;text-align:left;font-size:100%;left"> <div style="flex-direction:column; text-align:left"> ![圖片](https://hackmd.io/_uploads/r1S4qLabC.png =350x) </div> </div> </div> Note: This is an analytis by a Chinese mapper.

And they asign river code to each river. The number of list of river code is quite small compare to the actual number of river in Taiwan. We have to add more river on both Wikidata and OpenStreetMap, even though these rivers are not in the river code list. --- --- ## OSM 頂懸 ê 國小 - [Overpass Query](https://overpass-turbo.eu/s/1mZA)  ![](https://i.imgur.com/189UnMU.png) Note: OpenStreetMap 遮有記載的學校的視覺化結果 --- ## Wikidata 的國小  ![](https://i.imgur.com/v52wwKk.png) Note: Wikidata 檢索的結果 --- ## [Wikiproject Taiwan/Schools](https://www.wikidata.org/wiki/Wikidata:WikiProject_Taiwan/Schools)  ![](https://i.imgur.com/1YozljD.png) Note: 在地社群有建立協調的頁面，制定欲按怎編輯 --- ## 學校資料 ê 自動化表格  ![Elementary Listeria](https://hackmd.io/_uploads/BJEDF4uQle.png) --- ### 學校資料 ê 特性  * metadata 部分有[學校代碼](https://www.wikidata.org/wiki/Property:P7121)、地址、各語言名稱 * Wikipedia, Wikidata, Wiki Commons * 空間資料-OSM上有範圍 * 空間資料-Wikidata有收[經緯度](https://www.wikidata.org/wiki/Property:P625) Note: 學校有完整收佇 Wikidata，metadata 的資料有學校代碼、地址、各種語言名號。空間的部份是會當連結 OpenStreetMap，Wikidata 本身嘛會當收經維度 --- ## 學校資料 ê 挑戰  * 對 2019 年匯入了後，愛對上新 ê 狀況 * 看新聞加添新學校抑是處理廢除 ê 學校 * 整併日語維基百科遐重疊 ê 資料 * 分校 kah 分班資訊整理理 Note: 對 2019 年了後，無啥更新。Wikidata 遐有新設立的學校，是看著新聞去加的，抑是有人佇 OpenStreetMap 加添。除了更新資料以外，另外有日語維基遐重疊，毋過無偌濟。 --- ## [Name Suggestion Index](https://wiki.openstreetmap.org/wiki/Name_Suggestion_Index)  * 2013 年 10 月開始，附屬 iD 專案 * 2019 年獨立出來：[State of the Map US 2019](https://2019.stateofthemap.us/program/sat/mapping-brands-with-the-name-suggestion-index.html) 宣佈 * 一開始是沒人顧的 side project Note: Name Suggestion Index 是 2013 年 10 月開始的，附屬 OpenStreetMap 編輯器 iD 經營的，2019 年獨立出來。頭起先 NSI 是無人顧的 side project --- ## [Name Suggestion Index](https://wiki.openstreetmap.org/wiki/Name_Suggestion_Index)  * 迒語言，用 Wikidata 來做對應 * 向望 OSM 遮標示會當標準化 Note: NSI 希望會當解決迒語言的問題，用 Wikidata 來做精確對應。向望編輯遮會當靠 NSI 予連鎖商家標示統一 --- ## 台灣 ê 日常商家  ![](https://i.imgur.com/oA8GOwf.png) Note: 臺灣人日常的消費的店家有真濟有加添入去 --- ## NSI ê 台灣 ê 銀行資料  ![](https://i.imgur.com/AqkUfMq.png) Note: 親像所有的銀行攏有加添入去矣，配合 OpenStreetMap 遮匯入的銀行據點，相對是較完整的 --- ## 銀行的例 - [聯邦銀行三峽分行](https://www.openstreetmap.org/node/5758382974)  ![](https://i.imgur.com/nof4Ba5.png) Note: 聯邦銀行的三峽分行，除了地址以外，猶閣有 Wikidata 的連結 --- ## 台灣銀行 - NSI 數量 175 個  [![](https://i.imgur.com/qUaBSbH.png)](https://overpass-turbo.eu/s/1naT) Note: 因為時間關係，只有查全臺灣的臺灣銀行，照 NSI 的有 175 个 --- ## 最近 ê 重點 - 野外活動屬性提案  * 健行筆記山屋編號：[P13336](https://www.wikidata.org/wiki/Property:P13336) * 健行筆記山岳編號：[P13407](https://www.wikidata.org/wiki/Property:P13407) * 健行筆記步道編號：[P13406](https://www.wikidata.org/wiki/Property:P13406) --- ## 流程  * 屬性提案 * 掠蟲掠資料集 * 清理資料 * 匯入到 Wikidata * 加Wikidata連結到OpenStreetMap --- ## 屬性提案 - 健行筆記山屋編號提案  ![健行筆記山屋編號提案](https://hackmd.io/_uploads/rkriXqUVel.png) Note: --- ## 台灣宗教與民俗文化平台  ![台灣宗教佮民俗文化平台](https://hackmd.io/_uploads/ryG4r9IVee.png) Note: --- ## 華人教會名錄資料庫  ![Church List](https://hackmd.io/_uploads/rJ-aMCLEge.png) Note: --- ## [To-siā!](https://en.wiktionary.org/wiki/%E5%A4%9A%E8%AC%9D#Chinese) [sṳ̀n-mùng-ǹ!](https://en.wiktionary.org/wiki/%E6%89%BF%E8%92%99%E4%BD%A0) Thank you!  - :sheep: [GitHub](https://github.com/Supaplextw/) - Supaplex: [Wikidata](https://wikidata.org/wiki/User:Supaplex)，[OpenStreetMap](https://www.openstreetmap.org/user/Supaplex) - Or [email](mailto:dennis@wikimedia.tw) - Facebook group [Wikidata Taiwan](https://www.facebook.com/groups/2212207218990971/)、[OpenStreetMap Taiwan](https://www.facebook.com/groups/OpenStreetMap.TW/) Note: Here is my contact information, To-siā, sṳ̀n-mùng-ǹ!
