Where to find Azimuth Angle

[Teracotta]

Hello,

I would like to ask where to find Azimuth angle fo Sentinel-1. I was looking to Metadata and there is only the Incidence angle range (Incidence near and Incidence far). Do you know? please!

Hi @Teracotta,

If you meant Azimuth direction or heading of Sentinel -1 then this will help you -

Satellite Azimuth Direction/Heading

Heading, azimuth direction, of the Sentinel-1 product is provided in metadata as “platformHeading”. It is explained in Sentinel-1 Product Specification as follows Table 6-31 Data Type – productInformationType platformHeading: Platform heading relative to North [degrees]. Example from SNAP [image] Is this information what you are looking for?

It is with respect to North direction. Clockwise is positive and anti-clockswise is negative.

The link to the product specification provided above is broken.
The latest version of the product specification can be found in the SAR document librabry in Sentinel Online here:
https://sentinel.esa.int/nl/web/sentinel/user-guides/sentinel-1-sar/document-library

Be careful with the meaning of platform heading. This refer to the platform heading, and not to the azimuth directions of points in the image. Both are different, especially at high latitudes.
