Extract Urban Built-up Area (Urban Footprint) from SAR Data in the SNAP (Sentinel-1) 

You're welcome 😊

Glad you think so!

🙏

Sentinel 2 data can be used to extract urban built-up areas Especially the SWIR band

@@rsgis6997 can you please guide me through that process ?

Glad it was helpful!

Thanks

🙏🙏

The green and purple colors represent the built-up regions, each of which has more backscatter in one of the polarizations, VV polarization and VH polarization.

@@rsgis6997 If I only want to find vehicles on the road, how can I do it?

@@cambodianriverpig7613 You need better resolution images to extract the vehicle

Sentinel-1 images in SLC format are mostly used to extract subsidence and..., because we need intensity of images to identify urban areas, we used GRDH
