The idea is that you're modeling an irregular shaped object, a body of
water, a river or estuary, say. It's fairly common practice to use a
grid squished and rotated so that the main flow is along one axis, and
the other axis spans the flow in most spots. So there is a single

No query from me over there because I managed to overlook it. Many
thanks.

Hello all:
A question from a new user. I have data on a geo-referenced curvilinear
grid. This is a grid with 75 rows and 51 columns, is not aligned
north-south, and the rows and columns are not straight. (And the
coordinates are in meters.) I want to make image plots of this data,
but where

coordinate system and geom (eg. points vs tiles) operate
independently, you can draw image plots
