The current implementation in ArcGIS Pro recently added an alternative set of "Pairwise Overlay" tools (as of v2.7) that uses parallel processing to more efficiently process very large datasets. GRASS GIS (open source), although it was originally raster-based, has included overlay as part of its vector system since GRASS 3.0 (1988). [16]
Some GIS software, such as ArcGIS Pro, natively supports this model, with functionality including animation. Time-stamped boundaries , using the topological vector data model to decompose polygons into boundary segments, and stamping each segment by the time during which it was valid.
A virtual composite raster grid composed of images that are stored as separate raster files. This is stored as a polygon feature class with a row for each image including image properties such as image filenames and georeferencing information, and the shape representing the desired display extent of the image, enabling seamless composition of ...
A simple vector map, using each of the vector elements: points for wells, lines for rivers, and a polygon for the lake A vector dataset (sometimes called a feature dataset) stores information about discrete objects, using an encoding of the vector logical data model to represent the location or geometry of each object, and an encoding of its ...
Georeferencing or georegistration is a type of coordinate transformation that binds a digital raster image or vector database that represents a geographic space (usually a scanned map or aerial photograph) to a spatial reference system, thus locating the digital data in the real world.
With the release of ArcGIS Pro 3.0 in June, 2022 all *.aprx project files can be read by version 3.0; however, if the project is saved it will render the project file to be incompatible with version 2.9.x and earlier. [58] ArcGIS Pro 1.0 was released in January 2015. [59] ArcGIS Pro 2.6 was released in July 2020. [60] Noted features added ...
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.
Sliver polygons are typically created when polygons are automatically generated from lines that should be coincident (e.g., an international boundary following a river de jure, or two adjacent counties) but are not, due to the natural discrepancies that arise from manual or automated digitization. This can occur when a single layer is digitized ...
