Correctly read in coordinate system information #2
Comments
I'm going to try and have a go at this sometime soon. Just making a few notes here for my benefit: Example of Co-ords class in glue: https://github.com/glue-viz/glue/blob/master/glue/core/coordinates.py In rasterio, two attributes give basically the same data:

This would allow for example linking of different images by spatial coordinates.
Once we figure out how to get a transformation function, we should create a subclass of
glue.core.coordinates.Coordinates
that wraps this transformation, and we should attach the coordinates object to theData
instance in the data factory inglue_geospatial/data_factory.py
.To get the coordinates to be shown properly on plots, we will need to make it so that WCSAxes doesn't take a WCS object but a transformation function (or pair of functions).
