azimuth line and pixelcount of extracted tile/point

[Blockchainforcommons]

Hi,

As Sentinel-1 data requires pre-processing, e.g. radiometric calibration, thermal noise reduction, speckle filtering, we need to use the metadata files, delivered in the productinfo. As rio-tiler takes a part of the entire image, to derive the metadata, we need to know the Azimuth line and pixelcount of the extracted tile/point.

Does rio-tiler provide these, and if not, could you help me figure out how to get these in a convenient way. It would then good to add this feature to the tiler.

thanks,

Carst
