As mentioned in the title i need to integrate a raster to a satellite image but have no idea as to how to do this. I tried the add grid function and it works nice but is not permanent. I insert it via map composer but as this inhibits zooming I need to save it on the image. The person who will use the image as a map wishes to be able to zoom just as in any image. How is it possibly to permanently add the a raster with 10 square kilometre grid size permanently to a satellite image I have as TIFF format?
The problem you have to solve is that a vector grid is displayed in a scale-independent pixel size, while a raster image is defined by a fixed cell size.
You could rasterize your vector grid, and merge it with the satellite image, but zooming out the grid will get smaller until it can not be seen anymore.
The other way round, a 10km, 1-pixel-wide grid will lead to a screen full of lines hiding the satellite image completely.
So you can only make a grid for a most wanted scale.
