Some forms of temporal data began to be supported in off-the-shelf GIS software by 2010. Several common models for representing time in vector and raster GIS data include: [28] The snapshot model (also known as time-stamped layers), in which an entire dataset is tied to a particular valid time. That is, it is a "snapshot" of the world at that time.
Data extraction is a GIS process similar to vector overlay, though it can be used in either vector or raster data analysis. Rather than combining the properties and features of both datasets, data extraction involves using a "clip" or "mask" to extract the features of one data set that fall within the spatial extent of another dataset.
Another development in the 1990s was the public release of proprietary file formats by GIS software vendors, enabling them to be used by other software. The most notable example of this was the publication of the Esri Shapefile format, [ 5 ] which by the late 1990s had become the most popular de facto standard for data sharing by the entire ...

QGIS supports raster, vector, mesh, and point cloud layers. [4] Vector data is stored as either point, line, or polygon features. Multiple formats of raster images are supported, and the software can georeference images. QGIS supports shapefiles, personal geodatabases, dxf, MapInfo, PostGIS, and other industry-standard formats.

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.
