SRTM-30

SRTM-30

SRTM-30 is clearly the best of the 30 second  (about 1 km horizontal resolution ) global DEMs.  The only problem might be excessive elevations in urban areas because of buildings.

 

Download from USGS site  data (you need the  zipped HDR and DEM files, and the files are named for the NW corner; you must unzip and get the two files into the same directory)

Open new DEM  for manual opening of DEMs,  pick the HDR file.
