I am a recently graduated space engineer and I am amazed at how you are all developing this free course. Perfectly explained and full of interesting and useful information. This motivates me even more to deepen my knowledge in space. Thank you for these tutorials and well done!

[@kevalan1042]

Covered here: subsetting images with TOPS Split, applying precise orbits, TOPS Deburst, Multi looking, Terrain correction, TOPS Coregistration (Back geocoding), Interferometric coherence estimation, RGB composites, Layer manager (overlay/transparency).

Literally saved my day. Thank you ❤

[@ajaysaraswat6317]

Thank you very much sir for the excellent detailing 🙏🙏

[@scimonika]

I am very thankful to you for this informative video :)

[@kevalan1042]

why do we have to deburst and multilook again after the coherence estimate?

This is brilliant. Have you any plans to, or have you had need to do dual-pol decomposition with Sentinel-1?

[@arpanpaul9793]

Thank you for the clear explanation. I'm working on Sentinal 1 SLC data. After completing the following steps "S-1 Tops Split - Apply Orbit File - Calibrate - Deburst - Multilooking" I'm trying to go for 'Range Doppler Terrain Correction' but there is no output after hours of processing. I have internet and I tried the same process multiple times with different data but, there is no such output. Anything wrong with the software now?

[@saii1990]

Thanks for a nice tutorial. What is the optimal way to find the thresholds of coherence and mean images (any specific algorithms are there?). As the urbanization is a dynamic process, how to best utilize the time series sentinel data. In ArcGIS there is a model builder which helps to automate the geoprocessing tasks. If I want to do a sequence of steps for S1 image proceses in SNAP is there any way for automation?

[@VanyaShivakumar]

Hi Nice one to follow the steps, Can you suggest me what should be the System configuration to perform Snap tool.. I get error while processing S1for split function with an error message out of memory heap error etc etc...Please suggest

I did this for Cox's Bazar District but the output wasn't like this. It was totally black with few random white dots. is it because i used a large area? What should i do if i want to create the urban footprint of a large area?

[@hamidrezakohbanani6433]

What do you mean of footprint?

[@ebiebrahimikabak3612]

thanks

[@matsyanagendra]

first of all, thanks for the video its very helpful, I do some research on vegetation based on sentinel 1A and I have some question, it is possible to use the same way to mapping vegetation especially for mangrove? thanks

[@fontesegura]

Obrigado!

[@matsyanagendra]

could we use the IW GRD type to define urban footprint?

Hello How do I validate my results after extracting the urban mask for the city?
