pdmaptw v2.4.0

台灣縣市 / 鄉鎮市區 / 村里界圖，供統計圖表使用。

內容

• GeoJSON ( 47 檔 ): EPSG:4326 經緯度，真實地理位置。全國一份，另按縣市分檔。
• SVG ( 47 檔 ): 每區一個 path，id 為行政區代碼、data-name 為名稱，依縣市分組。
• CSV ( 1 檔 ): 行政區代碼、名稱、標籤定位點與面積對照表。
• manifest.json: 全部檔案的清單，含層級、範圍、格式、大小、SHA-256 與下載網址。

資料版本

• 縣市: COUNTY_MOI_1140318 ( 2025-03-18 )
• 鄉鎮市區: TOWN_MOI_1140318 ( 2025-03-18 )
• 村里: VILLAGE_NLSC_1150817 ( 2026-08-17 )

注意

SVG 的離島 ( 澎湖、金門、馬祖、釣魚臺、彭佳嶼 ) 位置經過位移，讓統計圖不會有大片空白，
因此不是真實地理位置。需要真實座標請用 GeoJSON。

界線經過簡化以利網頁繪製，不適合用於面積量測或套疊分析；CSV 的 area_km2 由簡化前的原始
界線計算，與內政部公布的土地面積統計仍有數個百分點以內的差異。

2.3.0

• map data now carries the official 行政區代碼 as properties.code ( 5 / 8 / 11 digits for
  county / town / village ), so consumers can join on a stable code instead of the
  Chinese name.
• add choropleth({data, key, scale, empty}) for filling regions from a value lookup,
  keyed by code or name.
• meta.source records which government shapefile release each file was built from.
• rebuild from the current data: county / town COUNTY_MOI_1140318 TOWN_MOI_1140318
  ( 2025-03-18 ), village VILLAGE_NLSC_1150817 ( 2026-08-17 ).
• drop the ld$ ( @loadingio/ldquery ) runtime dependency: init() now uses native
  Element.closest, so a plain <div> root works with no extra library.
• fix: simplification could leave a ring degenerate or wound the wrong way, which d3-geo
  reads as covering the whole sphere — one such ring painted the entire map. affected two
  村里 in v2.2.1.
• fix: 臺中市中區 was filtered out of the town map entirely.
• fix: filter.ls passed the quantization factor as an object, which silently disabled
  quantization. dist/county/ drops from 28MB to 300KB, and the whole package from
  33MB to 4.1MB.
• fix: fetch pointed at data.moi.gov.tw, which no longer exists. it now resolves the
  current download url from the data.gov.tw dataset API.
• fix: convert.ls picked the first .shp in the folder, which is no longer the main
  boundary layer now that the government zips ship supplementary shapefiles.
• npm run build now runs filter.ls as well, so per-county files stay in sync.
• past releases and the original shapefiles are kept under archive/.

2.2.1

• fix bug: released dist topojson files are not simplified.

2.2.0

• fire hover event instead of callback by popup for hover event.
• download and rebuild map files
• upgrade dependencies

0.0.4
