I was following http://www.qgistutorials.com/en/docs/working_with_terrain.html This tutorial.
I added hgt file from SRTM3 as a raster layer, and tried to clip a small area in 1:150000 scale. But this clipping takes eons of time, and the result file seems more than 100gb. I tried the same process with tif file from GMTED data, but the same symptom occurred.
How can I escape from this situation?
Is there anyway to shorten the clipping time, and create result file in small size?
edit 1) I'm not sure how the files looks like, but their size were very small. Looks like they were compressed.
edit 2) Following is the command in command line gdal_translate -projwin 13984505.7052 4710091.33247 14010189.9721 4674886.87201 -of GTiff -co "COMPRESS=LZW" C:/Users/myname/Documents/QGIS_test/NxxExxx.hgt/NxxExxx.hgt C:/Users/myname/Documents/QGIS_test/NxxExxx.hgt/cliptest.tif
-co "COMPRESS=LZW" line helped to reduce the size of the file, but still it takes really really long time to clip
