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]
ArcGIS Pro is desktop GIS software developed by Esri, which replaces their ArcMap software generation. [1] The product was announced as part of Esri's ArcGIS 10.3 release, [ 2 ] ArcGIS Pro is notable in having a 64 bit architecture, combined 2-D, 3-D support, ArcGIS Online integration and Python 3 support.
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.
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 ...
MXD – ESRI ArcGIS project file, 8.0 and higher; NTF – National Transfer Format file; OV2 – TomTom POI overlay file; SHP – ESRI shapefile; TAB – MapInfo TAB format; GeoTIFF – Geographically located raster data: text file giving corner coordinate, raster cells per unit, and rotation; DTED – Digital Terrain Elevation Data
MapInfo Pro is a database which manages information as a system of Tables. Each table is either a map file (graph) or a database file (text) and is denoted the file extension .TAB. Objects (points, lines, polygons) can be enhanced to highlight specific variations on a theme through the creation of a Thematic map. The basic data is overlaid with ...
Clipping, in the context of computer graphics, is a method to selectively enable or disable rendering operations within a defined region of interest. Mathematically, clipping can be described using the terminology of constructive geometry. A rendering algorithm only draws pixels in the intersection between the
The Greiner-Hormann algorithm is used in computer graphics for polygon clipping. [1] It performs better than the Vatti clipping algorithm, but cannot handle degeneracies. [2] It can process both self-intersecting and non-convex polygons. It can be trivially generalized to compute other Boolean operations on polygons, such as union and difference.
