I want to create a windmap. So I created a csv with coordinates with values for wind speed and direction, these represent my weather stations. I loaded the csv up in QGIS and marked a station. Then I chose Raster ==> interpolation ==> I chose the value direction and clicked "add". Then I chose the interpolation method Inverse Distance Weighting (IDW) for processing. Now I have a raster for my speed value and I have also processed one for the direction value.
Here is my Question:
Now I want to put a regular points grid over my interpolated rasters but it doesn't shows up? So I go to Vector ==> research tools ==> regular points.
Every time I want to create a regular points grid it proceeds and gives a result wich is an empty "regular points" layer?
I tried to use a layer, as a mask, and also tried it without a mask layer.
There are no errors or obvious failures? I tried it with other rasters and there were no problems at all.
It would be great to get some ideas and help.
