A GIS file format is a standard for encoding geographical information into a computer file, as a specialized type of file format for use in geographic information systems (GIS) and other geospatial applications. Since the 1970s, dozens of formats have been created based on various data models for various purposes
National Transfer Format (NTF) – National Transfer Format (mostly used by the UK Ordnance Survey) Shapefile – open, hybrid vector data format using SHP, SHX and DBF files (by ESRI) Spatial Data File – high-performance geodatabase format, native to MapGuide (by Autodesk) TIGER – Topologically Integrated Geographic Encoding and Referencing
The shapefile format is a digital vector storage format for storing geographic location and associated attribute information. This format lacks the capacity to store topological information. The shapefile format was introduced with ArcView GIS version 2 in the early 1990s. It is now possible to read and write geographical datasets using the ...

The binary format is widely used within Esri programs, such as ArcGIS, while the ASCII format is used as an exchange, or export format, due to the simple and portable ASCII file structure. The grid defines geographic space as an array of equally sized square grid points arranged in rows and columns.
For example, a raster named mymap.jpg should have a world file named mymap.jpgw. An alternative file naming convention that uses a three-character extension to conform to the 8.3 file naming convention uses the first and last character of the raster file's extension, followed by "w" at the end. For example, here are a few naming conventions for ...
A Geodatabase is a proprietary GIS file format developed in the late 1990s by Esri (a GIS software vendor) to represent, store, and organize spatial datasets within a geographic information system. [ 1 ] [ 2 ] A geodatabase is both a logical data model and the physical implementation of that logical model in several proprietary file formats ...
The Esri TIN format is a digital vector storage format for storing elevation information including breaking edge features. The Esri TIN format was introduced with ArcView GIS. The Esri TIN format consists of a collection of files with specific filenames and a common filename extension, stored in the same directory.
