--- tags: Disfactory, 違章工廠, 違章工廠舉報系統 --- # 違章建築檢舉輔助系統 開發文件 <small>從 https://hackmd.io/ockOrC1VRfWyOwV8fvMF2w 搬來</small> ## 專案目的 https://github.com/yoyo930021/Disfactory 建立一個方便的舉報違章建築的系統 舉報完會自動轉換成實際舉報所需資料並產生公文 方便地球公民基金會做後續向政府舉報的動作 ## 階段 1. ==now== 建立蒐集資料系統 2. 匯入已知的違章工廠資料 4. 提供給地球公民基金會使用的後臺 5. 背後轉換成公文 6. 串接 Bot 做到完全匿名 ## 開發需求 - 前後端分離 - 前端 (1 位) - Vue.js - Vue Composition API - [lib](https://github.com/vuejs/composition-api) - [RFC](https://composition-api.vuejs.org/) - OpenLayers - 地圖顯示的套件 - 國土測繪圖資服務雲用同一套方便作業 - TypeScript - 後端 (1-2 位) - 程式語言 - Node.js - Modern PHP - Python - 由最後負責後端的人討論決定 - 資料庫 - PostgreSQL - 有內建強大的地理查詢能力 - SQLite - 聽說跟 PostgreSQL 地理部分用同套 Lib - MariaDB - 單純比較熟悉 - 由最後負責後端的人討論決定 - 簡單爬蟲能力 - 可能需要分析國土測繪圖資服務雲的 API ## API - 工廠資料 - 使用者上傳 - 國土舊有資料(ronny wang 農地和工廠經緯度:[full-info.csv](https://gist.github.com/ronnywang/f8bbf008e641b296c755f0167b51a550)) - x,y,xmin,ymin,xmax,ymax - 可能的違章工廠座標(To be confirmed) - ==1== GET `/factories?lng={lng}&lat={lat}&range={km}` - 得到中心座標往外指定範圍的已有工廠資料 - response ```Typescript= Array<{ id: number, lng: number, lat: number, name: string, type: Enum, // 工廠類型 images: [{ id: number, url: string, alt: string }] report_at?: number // 回報日期 status: Enum // 已回報 | 編輯中 | ... (TBD) // post_process: string }> ``` > 還缺公文回報內容(照片) > 舊的違章工廠資料:地號中心點座標 > 新增違章工廠資料:使用者定位 GPS > 需要確認一下國土規劃的 API 有提供到多少的地段地號轉座標與多邊形 > post_process 用 html or markdown - ==2== PUT `/factories/{id}` - 新增編輯指定 id 的工廠欄位資料 - request body ```json { attribute1: value1, attribute2: value2, } ``` > 要有編輯紀錄 - ==3== POST `/factories/{id}/images` - 上傳指定 id 的工廠圖片 - content type: `multipart` - request body: ```Typescript= { 'image': 'image buffer here', 'data': { # provide this field will let 'path': 'https://i.imgur.com/123456.png', # the only field that cannot be null 'exif': { 'Latitude': 23.12, 'Longitude': 121.5566, 'DateTimeOriginal': '2020:03:21 12:33:59', } } } ``` - response ```Typescript= { token: string } ``` - ==4== POST `/images` - 上傳圖片 - content type: `multipart` - request body: ```Typescript= { 'image': 'image buffer here', 'data': { # provide this field will let 'path': 'https://i.imgur.com/123456.png', # the only field that cannot be null 'exif': { 'Latitude': 23.12, 'Longitude': 121.5566, 'DateTimeOriginal': '2020:03:21 12:33:59', } } } ``` - response ```Typescript= { token: string } ``` - ==5== POST `/factories` - 新增工廠 - request ```Typescript= { name: string, type: Enum, images: string[], other: string, lat: number, lng: number, nickname: string, contact: string } ``` > 少舉報人的聯絡方式(只有新增的時候會問):稱呼 & 聯絡方式(電話號碼或 email) > other 是 description 的意思,上限 1024 cha PS. 少了新增聯絡方式的流程 所以暫時沒設計相關 API > 還有地球公民基金會後台的 API 還沒開 > 還需要編輯紀錄 log 目前資料是五萬筆 ## 後端架構 ![](https://g0vhackmd.blob.core.windows.net/g0v-hackmd-images/upload_b6eba6c8d06a92b8b3bc7b0fddecdc2a) 這是最基本要完成的部份。如果後續有時間再加: - DB backup: 寫 cron job 或用個 master-slave (但不確定怎麼在 middle2 上設定) - cron job 打 Imgur:因為半年沒 query 就會刪掉 - asynchronous task queue: 座標轉地號和圖片上傳都可以在背景做掉,減低 blocking time。不過會有 data inconsistency 的問題,處理起來有點複雜。 - DB caching: 由於不會很常增加新的違章工廠,加上總資料量其實很小,可以有寫個 write-through 機制的 cache - Image backup and self-hosting ![](https://g0vhackmd.blob.core.windows.net/g0v-hackmd-images/upload_8318e305f7fd71fea7dcb3925be68b18) > type 是 fact_type > fact_id 用 uuid > 要不要新增的時候如果附近一公尺已有舉報工廠,會新增再已有工廠上=> 先開 issue > img 要存 uuid 和 imgur 的 path > img 要存上傳 created_time,最好存照片 EXIF 照相時間(沒有就 null)。上傳 imgur 時會把 EXIF 抹掉 > query_string: request body > action_type > action_body > ## 其它連結 - Firebase 相關,可能可以拿來處裡 Geo 資料 - https://github.com/geofirestore/geofirestore-js - https://angularfirebase.com/lessons/geolocation-query-in-firestore-realtime/ - https://firebase.google.com/docs/reference/android/com/google/firebase/firestore/GeoPoint ## API 研究 - https://maps.nlsc.gov.tw/ 從經緯度拿地段 ![](https://g0vhackmd.blob.core.windows.net/g0v-hackmd-images/upload_5c2c9ce7827ab7b0f04ccced1dec42ae) iTHome 鐵人賽 30天打造我的WebGIS https://ithelp.ithome.com.tw/users/20107816/ironman/1541 https://www.geoapify.com/leaflet-vs-openlayers/ Leaflet vs Openlayers https://stackoverflow.com/questions/32046601/convert-xyz-coordinate-of-a-tile-to-longitude-latitude [國土地段轉地號](https://maps.nlsc.gov.tw) - https://github.com/ronnywang/luz.tcd.gov.tw : ronny 用 opencv 算外框對回去 geojson - https://maps.nlsc.gov.tw/demo/105RGB%E8%89%B2%E7%A2%BC%E8%A1%A8.png 104 土地使用分類表 - https://docs.opencv.org/master/d3/dc0/group__imgproc__shape.html#gadf1ad6a0b82947fa1fe3c3d497f260e0 - opencv.js https://docs.opencv.org/3.4/d0/d84/tutorial_js_usage.html - https://github.com/oliver-moran/jimp - https://www.npmjs.com/package/replace-color - [imgur API 研究](https://hackmd.io/snF73YIRT2KZ4Tw1oQWb2g) - [運用 Django 上傳圖片的 API 教學](https://www.techiediaries.com/django-rest-image-file-upload-tutorial/) - [DRF_function-based-views](https://www.django-rest-framework.org/api-guide/views/#function-based-views) forEachLayerAtPixel
