Esri GIS software has included polygon overlay since the first release of ARC/INFO in 1982. [15] Each generation of Esri software (ARC/INFO, ArcGIS, ArcGIS Pro) has included a set of separate tools for each of the overlay operators (Intersect, Union, Clip, etc.).
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 ...
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.
Matthias Kramm's gfxpoly, a free C library for 2D polygons (BSD license). Klaas Holwerda's Boolean, a C++ library for 2D polygons. David Kennison's Polypack, a FORTRAN library based on the Vatti algorithm. Klamer Schutte's Clippoly, a polygon clipper written in C++. Michael Leonov's poly_Boolean, a C++ library, which extends the Schutte algorithm.
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 ...
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 ...
Some GIS software has aggregation tools that identify clusters of features and combine them. [20] Aggregation differs from Merging in that it can operate across dimensions, such as aggregating points to lines, points to polygons, lines to polygons, and polygons to polygons, and that there is a conceptual difference between the source and product.
The difference is that Liang–Barsky is a simplified Cyrus–Beck variation that was optimized for a rectangular clip window. The Cyrus–Beck algorithm is primarily intended for clipping a line in the parametric form against a convex polygon in 2 dimensions or against a convex polyhedron in 3 dimensions. [2]
