Topological Error Detection and Correction in QGIS

Here it going to learn about topological errors identification and rectification in detail using QGIS, one of the eminent open-source GIS software. Drawbacks are connected also with used polygons; sometimes you get some topological errors for example overlapping polygons or gaps between them which directly influence your spatial data quality. Below is the guide on how to manage to use QGIS’s tools to detect such errors in order to ensure that your data is always clean.

You will manage to find out how to use the Topology Checker plugin to solve most typical difficulties; to apply it for the further programming of the work and tight topological regulation of the fields in the datasets. Upon the completion of this tutorial, one will be in a position to improve on the quality of spatial data that feeds into map production hence improving on the quality of the maps. This being said, this guide is both for the one who never used QGIS before and for the one who has been using it for a long time and plans to enhance their knowledge on the management of spatial data.
