Where to find Azimuth Angle

[ghajduch]

Hi @mengdahl

The “platform heading” should be by definition the direction toward north of the platform. The point is that the azimuth direction within the product is not equal to the platform heading and is not constant. This is because a product is 2-dimensional + it is not on the nadir + the Earth is not flat.

I pushed an illustration of this here:

How to obtain the azimuth looking angle in sentinel 1 images through SNAP?

Hello, you can find it in the footprint tag. In my file it is at line 219-221. [image] The related documentation is in the Sentinel-1 Product Specification in Table 6-7 page 93. But you might want to look at these threads too: Where to find Azimuth Angle - s1tbx - STEP Forum (esa.int) Azimuth angle - s1tbx - STEP Forum (esa.int)
