Using a topology provides a mechanism to perform integrity checks on your data and helps you validate and maintain better feature representations in your geodatabase. In addition, you can use topologies to model spatial relationships between features.

- Topology in ArcGIS—ArcGIS Pro
ArcGIS includes topology layers in the map that are used to display topological relationships, errors, and exceptions. ArcGIS also includes a set of tools for query, editing, validation, and error correction of topologies.
26 Αυγ 2021 · In GIS, Topology is a set of rules that define how Point, Line & Polygon Features shares coincident geometry. This is a technique used in GIS analysis that averts the distortion of areas subjected to geometric transformations. Topology usually involves the use of different types of arc, polygons, lines, and other shapes. Types of Topology In GIS.
Topology is a collection of rules that, coupled with a set of editing tools and techniques, enable the geodatabase to more accurately model geometric relationships.
12 Οκτ 2010 · A GIS topology is a set of rules and behaviors that model how points, lines, and polygons share coincident geometry. For example: Adjacent features, such as two counties, will have a common boundary between them.
3 ημέρες πριν · Topology expresses the spatial relationships between connecting or adjacent vector features (points, polylines and polygons) in a GIS. Topological or topology-based data are useful for detecting and correcting digitising errors (e.g. two lines in a roads vector layer that do not meet perfectly at an intersection).
In GIS, topology is implemented through data structure. An ArcInfo coverage is a familiar topological data structure. A coverage explicitly stores topological relationships among neighboring polygons in the Arc Attribute Table (AAT) by storing the adjacent polygon IDs in the LPoly and RPoly fields.
