Python 读取 shp 图层数据：统计志远县图斑个数与罗丰县面积之和

1. 读取name字段中“志远县”图斑的个数： ```python import geopandas as gpd # 读取shapefile文件 gdf = gpd.read_file('data1/township.shp') # 筛选出name字段为"志远县"的图斑 zhiyuan_county = gdf[gdf['name'] == '志远县'] # 计算图斑个数 count_zhiyuan = len(zhiyuan_county) print("志远县的图斑个数：", count_zhiyuan) ``` 2. 读取area字段（面积），并计算“罗丰县”的面积之和： ```python # 筛选出name字段为"罗丰县"的图斑 luofeng_county = gdf[gdf['name'] == '罗丰县'] # 计算面积之和 total_area_luofeng = luofeng_county['area'].sum() print("罗丰县的面积之和：", total_area_luofeng) ``` ######[AI写代码神器 | 251点数解答 | 2024-06-30 01:05:04]
