GOES projection corners

Community matplotlib-users

Hi, trying to overlay maps on the new GOES16 satellite images from the raw data
direct from the satellite.

They send metadata indicating the corners of the image, but they send ULcrnr and
LRcrnr instead of what maplotlib wants, LLcrne and URcrnr.

Any suggestion on how to get the numbers maplotlib wants, or use the ones sent?

Thanks!

Sorry if this is a dup..

Congrats on getting the GOES-16 imagery. It's still (and probably always
will be) GOES-R to me :slight_smile:

Thanks! Images are amazing. I cheated and put the corners in for the US image
from the NWS display program, and the map plots fine. But they have
"mesoscale" images with dynamic locations, so you need to input those with
them.

Sample image, Northeast "Mesoscale", 50% resized.

Just so you can see, for example, this is the CONUS image of course GOES
projection

<attribute type="float" value="-152.109282"
name="geospatial_westbound_longitude"/>
<attribute type="float" value="56.761450"
name="geospatial_northbound_latitude"/>
<attribute type="float" value="-52.946879"
name="geospatial_eastbound_longitude"/>
<attribute type="float" value="14.571340"
name="geospatial_southbound_latitude"/>

-152 is the UPPER LEFT corner of course, in the pacific.
