In QGIS it’s possible to convert a points layer to a polygons layer in just a few steps. To do so there are some minimum requirements for the points layer, because QGIS has to know which points should be grouped to a polygon and in which order these points must form a polygon. To illustrate this I have created a test layer with 7 points. I added two new fields: “polygon” and “order”. The field “polygon” indicates which points have to form a polygon together. In this example the result should be two polygons (1 & 2). The field “order” indicates in which order the points should be connected to form a polygon. In this example the result will be a triangle and a quadrangle (quadrilateral).Continue reading “Convert a points layer to a polygons layer in QGIS without using plugins”
Since a couple of years I maintain 4 web pages with lists of WMS, WFS, WMTS and XYZ tile services that contain data for Belgium. When I recently attended the FOSS4G Belgium conference in Brussels, it became clear these web pages are pretty popular with the Dutch speaking GIS folks at the conference. The WMS page was even on one of the slides for the keynote by OGC president Bart De Lathouwer.Continue reading “List of webservices with data for Belgium now also in English and French”
I recently moved the demo repository of phpQGISrepository (https://plugins.stuyts.xyz/) to a new webhost and since then it didn’t work anymore in QGIS 2.18. In QGIS 3.x and in all webbrowsers it still worked just fine, but in QGIS 2.18 it gave a 400 error (Bad Request).Continue reading “A simple fix if phpQGISrepository doesn’t work in QGIS 2.18”
I created a QGIS style that will draw a curved line between a point and the closest other point in that same layer. This way you can visualize nearest neighbours and also see clusters of points.Continue reading “Visualize nearest neighbours with Geometry Generator in QGIS”
I released version 1.1 of ZoomToBelgium for QGIS today. This QGIS plugin creates a button to zoom to any of the Belgian Municipalities or Districts. In this new release districts were added.
Recently this project migrated from Github to GitLab. From now on it can be found on https://gitlab.com/GIS-projects/ZoomToBelgium.
You can download this new version of ZoomToBelgium from within QGIS, because this plugin is available in the official QGIS plugin repository.
Based on the ETOPO1 Arc-Minute Global Relief Model and the Natural Earth Vector data, I made a relief map of Europe using QGIS. You can download the high resolution version from this blog.
