As for the storage of spatial data can use PostGIS database. PostGIS is thedevelopment of PostgreSQL that can store and process spatial data type. In this paperwill be described GIS applications using MapServer and PostGIS to assist Dinas TataRuang dan Cipta Karya in terms of doing the analysis Location Permit and the LandUse Permit. The results of this research is expected that each applicant whowants to makeLocation Permit or Land Use Permit in accordance with therules that have been defined.Keywords: Geographic Information Systems, MapServer, PostGIS, Location Permit, Land Use Permit
