plateaukit's Issues

都市モデルのprebuild時にGeoDataFrameのcrsプロパティへのアクセスでAttributeErrorとなる

東京都23区データ（plateau-tokyo23ku-2022）のインストール時にエラーとなります。すべての都市モデルを調べたわけではありませんが、東村山市（plateau-13213-higashimurayama-shi-2020）、川崎市（plateau-14130-kawasaki-shi-2022）、横浜市（plateau-14100-yokohama-shi-2022）では出ていません。

データのダウンロードはうまくいっているようです。そこでローカルのデータに対してprebuildしてみました。

from plateaukit.prebuild import prebuild
dataset_id = "plateau-tokyo23ku-2022"
prebuild(dataset_id, split=1, simple_output=False)

すると、下記のエラーが発生します。

AttributeError: You are calling a geospatial method on the GeoDataFrame, but the active geometry column to use has not been set.

これは、GeoPandas v0.12で変更された下記が影響しているようです。

Accessing the crs of a GeoDataFrame without active geometry column was deprecated and this now raises an AttributeError (#2578).
