Thomas Lavergne@phil_browne @SigneAaboe I understand. I've mostly reprojected the data (using #pyresample) before plotting. But it is an overhead one might want to avoid.
@EL_Uatu @ruthpozuelo if you know the lat/lon of each of you crime "cell", and the projection information to go from x/y to lat/lon you can use #pyresample (from the #pytroll ecosystem).
That's what I use for plotting satelitte and weather data. But #cartopy or #basemap can probably do the transform for you if the ony thing you want is plotting.
