Im working with QGIS 3.x, and i have a polygon layer, and each polygon has a value. i want create a point layer (like random points) but based on each polygon value. For example: polygon 1 value = 3 then add 3 random points, polygon 2 value = 12, add 12 random points and so ...
I too cannot for the life of me, for the case of multiple sepearate objects / features (points or polygons) with the same attribute value**, achieve a single label which has multiple callout lines anchored to each of the objects / features. I feel very stupid! Other things that I ha...
In this lesson I will show you how to split a polygon into several polygons using lines from another layer You will learn how to • Install the digitizing tools plug-in ... QGIS : create map using vector data model(points,lines,polygons) create map using vector data model(points,lines...
Let’s remove the unnecessary layers. Hold the Shift key and select Sampled Points and 2018_Gaz_ua_national layers. Right-click and select Remove to remove them from QGIS. When prompted for Remove 2 legend entries?, select OK. Now we will use the counties layer to sample the raster and ...
