Hi Alex
Hello. I am a newbie in Python.
Can you please post the final code with the conversion of lat_min to degrees as well as the spelling correction on the word latitude in the get-bounding box function?
@alex and Geospatialology: Also, kindly confirm that this will work when finding a polygon shape on the GIC (Geospatial Intelligence Consortium)/Vexcel platform.
Thank you.
Best regards
