Hi, I have a little problem. (and sorry for the crosspost of this)
I'm trying to do the following:
Convert _projected_ shapes from a Map object into logical matrices.
That is, rasterize a shape into a logical "intheshape" and
"outoftheshape" matrix.
What I'm trying to do is get an 'equalarea' estimate of the area of
intersection between two overlapping shapes, without any concern about
there being holes in the shapes. I know owin can deal with most of this,
but for sure it doesn't support geographic projections, which will allow
the 'equalarea' estimate to be equal.
An idea I had was to pipe the output of the maptools Map plotting
function map into the matrix. But I really have no idea how to do that
at this point in my R education.
Any suggestions are extremely welcome.
Cheers,
James
