How do I resamp a GeoTIFF image in QGIS?
In QGIS this can be done by using r.rsamp.interp of the GRASS toolbox. It allows for increasing or decreasing raster resolution. This tool allows for selecting many Sampling Interpolation Methods (nearest, bilinear, bicubic). Also allows cropping or masking an image during the resampling process with the Extention of Region GRASS.

How can I increase the extent of my raster?
In the Result box – select a layer which has the area you want your raster to cover and click ‘Current Layer Extent’ or define the X,Y,etc values yourself. A very simple process. Just right-click on the raster for which has to be changed and click Save As. Further, put the extent manually and click OK.
How to resample image to same resolution in Photoshop?
I normally use the Raster Alignment tool. It’s localized in the raster tab and can be used to set rasters to the same extent too. It can also perform some operations when resampling to a new resolution (such as mean, min and max value, etc.).
Is it possible to resample GeoTIFF images to same resolution?
This is easy in QGIS too, though a little less obvious. There are a couple of ways you can do it:
Are there any plugins for sampling raster data?
Often, one needs to extract the pixel values at certain locations or aggregate them over some area. This functionality is available in QGIS via two plugins – Point Sampling Tool and Zonal Statistics plugin.
Where do I find the Georeferencer plugin in QGIS?
The first step is to start QGIS, load the Georeferencer Plugin (see The Plugins Menus) and click on Raster ‣ Georeferencer , which appears in the QGIS menu bar. The Georeferencer Plugin dialog appears as shown in figure_georeferencer_1.
