SL_2_LST georeferencing problem


#1

After opening this product
S3A_SL_2_LST____20181214T050610_20181214T050910_20181214T060739_0179_039_105_0360_SVL_O_NR_003.SEN3
I noticed that it is upside down. See screenshot below:


It is the Gulf of California, so it should look like

What is wrong? I am opening the xdumanifest.xml, the x, y, latitude and longitude bands are read properly.
Thanks in advance for your help.

You are using an image from an ascending orbit, meaning that the satellite is acquiring data line by line from south to north.

In consequence, the first line acquired is the southernmost one. That the reason why this line appear in the top : it is actually the first one read by the software. Similarly, the last line acquired is the northernmost one. It then appeared at the bottom of the screen.

The image appear flipped. But don’t worry, after georeferenciation, everything will be alright :wink:
