使用PostGIS将csv表与县shapefile相交

Question

您好我有一个csv表名德州和一个县shapefile名称txcounty.shp

我尝试使用以下内容来获取与txcounty.shp相交的点。但它不起作用。

CREATE TABLE txintect as (
    SELECT DISTINCT ST_Intersection (texas.the_geom, txcounty.the_geom)    
FROM
    texas_geometries AS texas,
    txcounty_geometies AS txcounty
    WHERE texas.name='Hutchinson' 
    AND ST_Overlaps(texas.the_geom, txcounty.the_geom)
);

Answer 1

假设您已在数据库中导入shapefile和csv，您是否尝试过ST_intersects函数而不是ST_Overlaps
