AutoCAD DXF – contour elevation plots in AutoCAD DXF format (by Autodesk) Cartesian coordinate system (XYZ) – simple point cloud; Coverage – closed, hybrid vector data storage strategy. Legacy ArcGIS Workstation / ArcInfo format with reduced support in ArcGIS Desktop lineup. (by ESRI)
This was most common from the 1970s through the early 1990s, because GIS software developers had to invent their own geometry data structures, but incorporated existing relational database file formats for the attributes. For example, the Esri Shapefile format includes the .dbf file from the DOS dBase software.
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 ...
QGIS supports shapefiles, personal geodatabases, dxf, MapInfo, PostGIS, and other industry-standard formats. [5] Web services, including Web Map Service and Web Feature Service, are also supported to allow use of data from external sources. [6] QGIS integrates with other open-source GIS packages, including PostGIS, GRASS GIS, SAGA GIS, and ...
It is a tool for visualizing and processing spatial data, characterized by its friendly user interface and access to multiple data formats, both vectorial (in a file, such as Shapefile, GML, KML, DWG and DXF, or a database, such as PostgreSQL, MySQL, or Oracle) and raster (TIFF, ECW, MrSID, or other georeferenced image files, such as BMP, GIF ...

gvSIG, geographic information system (GIS), is a desktop application designed for capturing, storing, handling, analyzing and deploying any kind of referenced geographic information in order to solve complex management and planning problems. gvSIG is known for having a user-friendly interface, being able to access the most common formats, both vector and raster ones.
Plugins are provided for Autocad (for designers), ArcGIS, open source QGIS (for analysts & designers) and as a standalone Python version that works on 2D or 3D shapefiles enabling use in other GIS software and custom projects. sDNA standardizes on the network link as a unit of analysis, and computes a wide variety of closeness, betweenness ...
