How to export KMZ with image cross -180/180?

Microwave Toolbox
#1

I can not product the kmz for
S1B_EW_GRDM_1SDH_20171004T103521_20171004T103621_007678_00D8F6_A17F.zip

Read > Calibration > Terrain Correction > geotiff > kmz

This is Ross Sea.

Two things I notice:

  1. You don’t need the export to geotiff step, you can directly use the output of the terrain correction module
  2. You need WGS84 as a coordinate reference system when you want to export as a kmz.

Thanks for reply, can you tell me from step 1 to kmz with condition
data in dB and threshold from -26dB to -4dB.

  1. Thermal noise removal

  2. (Apply Orbit file)

  3. Calibration to Sigma0

  4. Range Doppler Terrain Correction
  5. Conversion to db
  6. Export to KMZ

Just for curiosity, why thermal noise removal in this case?

just to go sure to be honest :slight_smile:
Don’t know if it’s really necessary but if he is using data in EW (extra wide) mode I could imagine that there are some unwanted patterns.

I am not successful with step Export to KMZ. I am waiting more than 4 hrs, but still running.

try it for a subset first.
