A good video and as @rajeshvg399 mentions, these data are not DEMs derived from ALOS PALSAR. They are derived from SRTM +/- NED (USA). The DEMs downloaded here are used for terrain correction of SAR data. They are upsampled from 30 meters to 12.5 meters
This video is very useful. Thank you for uploading this video and expect more such videos from you. I have a doubt in this. The DEM file shows values ranging from -121 to -1. So that can't be the elevation value right ??? So is there any further processing required to get exact Elevation value from ALOS PALSAR DEM. Please reply for the same.
Thank you so much for the video. Unfortunately I am unable to find the Hi-Res Terrain Corrected part i only have Level 1.1 Image and Level 2.2 image. How best could you help me
Hello, this is useful data, if you need the latest you can go for cartosat DEM data still it not available for current years, it may be 2016 data. Thanks for your valuable question.

this was very helpful. thank you!
Thanks you Nasim Sadra
Thank you, this is very useful.
First thanks for helpful video, pls what different between dem level 1.0 and high resolution dem
Its not original alos palsar dem. Just resampled srtm data used for rtc processing
It means fake 12.5m DEM !!!!!!!!!
What is vertical accuracy?
good voice
Thanks Luxaeternae
it is good video.but when i open it only the black back ground seen .what is it's problem?
The highs are mean sea level?
How to create DEM on this image..?
Hello Sree Chaitanya, when you download this data, it does have DEM data for usage, you can utilize it. Thanks for your valuable question.
