如果你是通过编程方式读取Shapefile,可以在读取过程中添加异常处理机制,捕获并处理类型转换错误。 示例代码(Python + geopandas) 代码语言:txt 复制 import geopandas as gpd try: # 尝试读取shapefile gdf = gpd.read_file('path_to_your_shapefile.shp') except ValueError as e: print(f"读取时发生错误: {e...
python readshapefile 找到了 'utf-8' codec can't decode when using readshapefile on python basemap - Stack Overflow 其中提到的，或许对你有用：去把你的要导入的文件 bou2_4p.shp 去（比如用VSCode）转换为UTF-8编码 估计就可以了。关于VSCode，详见：文件编码 · 史上最好用的编辑器：VSCod...
读取shapefile时从dbf文件中删除Matplotlib Basemap中的空值 、、、 因此,我试图在python中读取一个shapefile,以便在matplotlib basemap中显示。如果不使用Basemap,我似乎无法将shapefile发送到matplotlib或mpl_toolkits,但是basemap一直给我提供这些错误。 urcrnrlon=36.5, urcrnrlat=33.7) map.readshapefileTraceback (most ...

read_file函数是geopandas的一个核心功能,用于读取地理数据文件(如Shapefile)。通常,任何较新的geopandas版本都应该包含这个函数。如果你使用的是非常旧的版本,可能需要更新geopandas。使用以下命令更新geopandas: bash pip install --upgrade geopandas 确认代码中read_file函数的调用方式是否正确: 确保你在代码中正确...
