1 Οκτ 2016 · Topology refers to the spatial relationships between GIS features or objects. It is important for network routing and maintaining data quality and integrity when features are shared across layers. Geodatabases provide the strongest topological functionality, storing relationships in topology rules and feature classes.
1 Δεκ 2023 · The term ‘uses’ indicates topology being used in the methodology of a 3D GIS study to achieve the objective. Based on the review, we were able to categorise the literature into 3 main uses of...
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.
A topology helps monitor and protect the spatial relationships in a feature dataset. A feature class can have no rules, a single rule, or several rules. A topology rule can monitor spatial relationships of features in a single feature class, or the relationships that exist between feature classes.
Given this background, the aim of this chapter is to outline a framework within which GIS can be linked with other analytical tools in such a way as to offer commercial organisations support in constructing strategic development plans. Such a framework is likely to be built upon the following sequence: data information ⇒ intelligence ⇒ action.
16 Απρ 2014 · In this article, an attempt is made to obtain new topological structures that will help in the field of GIS. This article introduces a concept of feature relationship between objects based on topological properties.
