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.

GRASS supports raster and vector data in two and three dimensions. The vector data model is topological, meaning that areas are defined by boundaries and centroids; boundaries cannot overlap within one layer. In contrast, OpenGIS Simple Features, defines vectors more freely, much as a non-georeferenced vector illustration program does.
QGIS functions as geographic information system (GIS) software, allowing users to analyze and edit spatial information, in addition to composing and exporting graphical maps. [2] QGIS supports raster, vector, mesh, and point cloud layers. [4] Vector data is stored as either point, line, or polygon features.
The GeoPackage standard describes a set of conventions (requirements) for storing vector features, tile matrix sets of imagery and raster maps at various scales, schema and metadata. A GeoPackage can be extended by using the extension rules as defined in clause 2.3 of the standard.
[1] [2] Having been used by many students, teachers and researchers for more than two decades, ILWIS is one of the most user-friendly integrated vector and raster software programmes currently available. ILWIS has some very powerful raster analysis modules, a high-precision and flexible vector and point digitizing module, a variety of very ...
Visualize vector and raster data on the globe or in one of the map projections. Visualize sub-surface 3D scalar fields as isosurfaces or 2D cross-sections. Export reconstructed data as a time-sequence of exported files. Use plate polygons (with dynamic boundaries and deformation) to calculate velocity fields.
Mapnik is an open-source mapping toolkit for desktop and server based map rendering, written in C++. Artem Pavlenko, the original developer of Mapnik, set out with the explicit goal of creating beautiful maps [2] by employing the sub-pixel anti-aliasing of the Anti-Grain Geometry (AGG) library. Mapnik now also has a Cairo rendering backend.
