Re: Understanding use of epsilon in transform.rowcol

Sorry for the late reply. I've just returned from vacation.
We've found that we need to account for float imprecision when inverting the forward geotransform. Specifically, we intend (with op=floor, the default) that points on the left edge of pixels in column 0 to compute as within column 0 and we want points on the boundary between column 0 and column 1 to compute as within column 1. Now, this is only an internal detail. We may yet determine that there is a better way to deal with the precision issues and I suspect there probably is a better way.
