Geocoding - get all records within a boundry. As far as design patterns, the Yelp question is pretty standard stuff. Create a spatial index on the geometric column: SELECT CreateSpatialIndex('places', 'geom'); With a spatial index, queries involving spatial terms can be executed much faster, significantly enhancing performance. I found it very difficult to design cache key for geospatial query results from MySQL. One table has point information as below - (Point Table) Another table has line information as below - (Line Table) What I want to do is match the points from point table to the line on line table (based on intersection of point and line) and join the two tables to get hwy_link_id/hwycov_id corresponding to each station_id.
