據 According to
在 OpenStreetMap 台中市有 1203512 門牌點物件，
in OpenStreetMap Taichung has 1203512 address points items.
惟政府資料，
However, looking instead at the government’s data,
$ wc --lines *
1305433 114年10月GIS門牌_台中市_TGOS__WGS84.CSV
1307597 114年11月GIS門牌_台中市_TGOS__WGS84.CSV
已有 200000000+ 點。哈哈騙你。反正 1307597 比 1203512 多。
We find 200000000+ points. Ha ha, fooled you. OK, only 1307597, which is
still more than 1203512.
是的。扣掉 CSV header 仍 1307596.
Oh yeah, got to remove the CSV header. 1307596.
且全台大概如此。所以建議建立定時更新機制。
I assume the same pattern exists for the rest of Taiwan.
Therefore I say it is high time a system for regular updates is
implemented.
大家除了 import 之外，應開始思索維護。
So aside from imports, please also think about maintenance.
