ESA Echoes in Space - Land: Forest mapping with ALOS PalSAR

[@pokkiri]

very easily understandable video. thank you for making this!

[@mamobongo751]

In the tutorial, we calculate the HH/HV ratio as - indeed - HH divided by HV. But it looks like the bands are in dB units. Shouldn’t we calculate the ratio in that case by subtracting HV from HH as a property of logarithms?

[@kevalan1042]

Same question! Very nice tutorial though

[@mit-cycle]

Can somebody guess why I get another result for my froest mask when using the -15 threshold?

[@kevalan1042]

Covered in this tutorial: collocation, speckle filtering, mask using an expression.

Thanks Sir..i'am a newbie...so clear explanation!

[@mapmyops]

can we do the same analysis with VV over VH?

[@niyonkuruetienne6406]

thank u Sir,
now if is possible upload video shows how to estimate forest height by using RADARSAT images 2 in SNAP

[@amiraabdo4426]

from where can I download the RADARSAT, Please.

[@yuvrajrathore7497]

Sir,how can I calculate area covered by forest using snap..please reply sir

[@tarikulislam7610]

I guess, you can easily do it in ARCGIS after importing as tif image!

[@mapmyops]

by creating a mask and computing mask area within snap

nice tutorial
