The Geospatial Data Abstraction Library (GDAL) is a computer software library for reading and writing raster and vector geospatial data formats (e.g. shapefile), and is released under the permissive X/MIT style free software license by the Open Source Geospatial Foundation.

The origin of the geodatabase was in the mid-1990s during the emergence of the first spatial databases.One early approach to integrating relational databases and GIS was the use of server middleware, a third-party program that stores the spatial data in database tables in a custom format, and translates it dynamically into a logical model that can be understood by the client software.
Because a grid is a sample of a continuous space, raster data is most commonly used to represent geographic fields, in which a property varies continuously or discretely over space. Common examples include remote sensing imagery, terrain/elevation, population density, weather and climate, soil properties, and many others. Raster data can be ...
A free, open source version is available. Kalypso – Uses Java and GML3. Focuses mainly on numerical simulations in water management. TerraView – Handles vector and raster data stored in a relational or geo-relational database, i.e. a frontend for TerraLib. Whitebox GAT – Cross-platform, free and open-source GIS software.
Raster-based stacked surfaces depict the surface of each buried geologic unit, and can accommodate data on lateral variations of physical properties. In this example from Soller and others (1999), [32] the upper surface of each buried geologic unit was represented in raster format as an ArcInfo Grid file. The middle grid is the uppermost ...
Cost distance tools are available in most raster GIS software: GRASS GIS (often bundled into QGIS), with separate accumulation and drain functions; ArcGIS Desktop and ArcGIS Pro, with separate accumulation (Cost Distance) and drain geoprocessing tools, as well as Corridor generation. Recently, starting with ArcGIS Pro version 2.5, a new set of ...
ESRI's ArcGIS 8.3+ has the capability of rubbersheeting vector data, and ArcMap 9.2+ may also rubber-sheet raster layers.; Autodesk's AutoCAD Map 3D [1] and AutoCAD Civil 3D (which includes most of AutoCAD Map 3D's functionality) allows a user to rubbersheet vector data, and Autodesk's Raster Design (an add-in product for AutoCAD-based products) allows a user to rubbersheet raster data.
