PostGIS is a spatial extension of PostgreSQL which is an open source relational database system.This paper analyzes sever-al existing modes of heterogeneous spatial data which currently works in the field of geographic information, proposes an integrated ap-plication solution of multi-source spatial data for PostGIS database combining the method of PostGIS spatial data organization, and fi-nally conducts a visual application development practice in environment of .Net development.
