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 calculate average temperature for each ...
My goal is to replace the raster DTM with a MESH for 3D display - withthe ability to edit the MESH at important points. The builtintriangulation of the QGIS 3D viewer (where you can have a raster DTM asa terrain source) is sometimes doing weird things - I'd like to controlthat better...

Raster Interpolation is a QGIS plugin to interpolates values on raster layers. It browses a vector layer of points, interpolates at their position the value of a raster layer and save the value in a chosen field of the vector layer. Interpolation can be nearest, linear or bi-cubic. Simple...

Compared to the standard raster georeferencer tool of QGIS, which needs control points and an export, this plugin allows the visualization of the result immediately, on top of the other layers of the map. Install From the QGIS plugin registry In QGIS, open the "Plugins" > "Manage and ...
10.Interpolation– Interpolation techniques estimate unknown values based on existing sample points. The output of interpolation (such asIDW,kriging, or spline) is a raster surface. If you’re looking for more examples of raster tools, here are more examples in theRaster Analysis Toolbox in ArcGI...
How do I join layers in QGIS? How do I group layers in QGIS? There are two ways to do this: Press the icon to add a new group. Type in a name for the group and press Enter . Now click on an existing layer and drag it onto the group. ...
A new Natural Earth quick start kit (158 mb) has been added to provided a small sample of the Natural Earth themes styled in an ArcMap .MXD document (read more at the Esri Mapping Center soon) and in a QGIS document. OSGeo Live DVD now includes small sample of Natural Earth themes ...
