I have around 30,000 shape files (also available as KML) that I would like imported into a PostgreSQL database. I would then like a SQL query written that will accept a coordinate (lat/lng) point and will return 1) whether the point intersects any of the 30k polygons 2) if so, which polygon.

Hi Tim, I do PostgreSQL/PostGIS for my Masther thesis. First need to instal PostGIS extension ([login to view URL]) for PostgreSQL database, because PostGIS provides spatial objects for the PostgreSQL database. Then you import SHP files using "Shape File to PostGIS importer". Need to be used SRID number 4326, because this SRIB number mark WGS84 projection ang Google Maps use WGS84 projection. Then you run ST_Intersects. ST_Intersects returns TRUE if the Geometries/Geography "spatially intersect in 2D" - (share any portion of space) and FALSE if they don't (they are Disjoint), for geography - tolerance is 0.00001 meters (so any points that close are considered to intersect). SQL code look something like this: SELECT ST_Intersects('POINT(0 0)'::geometry, 'LINESTRING ( 2 0, 0 2 )'::geometry); Please tell me what you think. Best, Darko

Hello, I'm a GIS specialist and I'm intensively working with PostGIS for 2 years. This is a straightforward task for me. I just need to know a few things: 1) Do you have 30k files or 30k features in a single file? 2) Which coordinate systems do you use?

I have 7 years experience in PostgreSQL and Postgis. Importing KML is no problem because Postgis have ST_GeomFromKML function. In one of my projects I writed SQL which analyse point intersection with 600k poligons. I will do this work quick and quality.
