Processing data block size and offset

Post by karthickmurugan »

Hello

I want to increase the processing block size and offset for HICO from size (200, 512) to size (1800, 512) and offset to (1800, 0) also.

Could you help me?

Dear Karthick,

The blocks size and offset are related to how Polymer processes the input product block by block. I guess you'd rather want to process a subset of the image, is that correct? If so, you can pass the options sline, eline, scol and ecol to process a subset of the image.
Example:
Level1_HICO('H....L1B_ISS', sline=100, eline=200, scol=300, ecol=400) # to process lines 100 to 200 and columns 300 to 400

Cheers,
François

Hi,

Is it possible to mention Latitude and Longitude instead of line and columns to process the subset?

No, it is not possible currently. You would require an external script to extract the coordinates from a range of latitude/longitude.
