After downloading an SRTM geotiff (DEM) from USGS's website, I would like to convert it from GCS to a projected coordinate system. After opening it in QGIS:
Is that enough if I simply just click on 'save as...' and set CRS from WGS84 to the preferred PCS?
Or should it be done like 'Raster > Projections > Warp'?
(I feel like it is not that easy and there is a trick somewhere...)
