縣市界有洞的問題 #28
Comments
不,是因為原始資料的邊界沒有共用,所以就被分別 simplify 了 |
@clkao 我也覺得 topojson 是不是有問題耶... 我用 twVote1982.topo.json 跑 d3 的 topojson.feature (topojson 面積) 會變成一片漆黑(應該是有破洞) 用別的 topojson 可以跑 之前我用 leaflet 做的圖 可以成功(因為是用線來畫),是不是有破洞?還是我那裡搞錯... |
我覺得應該不是 simplify 的問題,是否是原始資料問題? |
twCounty2010.topo.json 是可以畫的, 不過縣市邊界有洞 |
我突然發現。使用ShapeViewer看 TWN_COUNTY.shp 並沒有 D3+Leaflet 那個縣市界有洞的問題耶。
會不會那個洞其實是 Simplify 之後的失真,不是資料面的Bug?
