Naming of Sentinel 1 L2 products

Hi Sen4CAP team,

For Sentinel 1 L2 product naming, how do we know which file is for ascending orbit and which file is for descending orbit?

Hello Ant,

It is not in the name of the product. But you can retrieve it from the system database. In the product table are listed all the processed products with a series of information. For the amplitude and coherence products, there is an orbit_type_id which gives the infos if it is ascending (1) or descending (2). To check this you should:

  • connect to the system databse: psql -U admin sen4cap
  • if you want, check the orbit_type table: select * from orbit_type;

  • if you want, check the product_type table: select * from product_type;

  • if you want, list all the amplitude products that are ascending: select name from product where product_type_id=10 and orbit_type_id=1;
