I have received a GeoTiff file, whose pixel spacing is provided in degree (e.g. +1° to the right, -1° down). Of course, this means that the actual, metric pixel spacing changes in relation to the latitude, which is bad, if you want to relate pixel distances to actual, real-world distances. What is the straight-forward procedure to transform the image in such a way that the result is squared, metric pixels (e.g. +1m to the right, -1m down)?
For sake of completeness: The original image is provided in WGS84-latlon coordinates (EPSG:4326), the final image should be projected to the proper UTM zone (e.g. EPSG:32632).
I figure I'll probably first have to reproject the dataset. But then still the question remains about how to resample the resulting, reprojected image so that its pixel size can be set to an arbitrarily chosen, square size?
Using any distance measuring tool within QGIS is not an option, as I need to export the image again as a GeoTiff in order to process it externally with a different software.
