GIS Formats

A web mapping service (WMS) consists of geospatial data hosted on a GIS server with standards set by the Open Geospatial Consortium (OGC).

COGO (Coordinate Geometry) is a tool that maps the geometry from survey plans for land parcels, road allowances, and property easements.

How well do you know GIS formats? GIS technicians manage, share and create data in various geospatial data formats. See our list of GIS formats

Geodata is location data stored in a Geographic Information System (GIS). By using geographic data, we better tackle problems that require spatial thinking.

If you’re a bit confused whether or not to use a file geodatabase (*.gdb) or a personal geodatabase (*.mdb)… Here’s everything you need to know.

Lossless compression (like JPEG) retains values and lowers file size. However, lossy compression (like LZ77) reduces file size by eliminating redundancy.

From geodatabases to PostGIS, spatial databases have quickly become the primary method of managing spatial data effectively in a GIS.

Over the years, the USGS has been a driving force in the production of GIS data. The USGS formats we explore are DLG, DRG and DOQ.

Deploying efficient raster GIS compression techniques means reducing storage space. It can save money, time and also help network performance.
