Dear list,
I'm trying to bring an ASCII raster file into ArcGIS that resulted from
calling the R function Tsp(), which is in the "fields" library, followed
by the use of the function predict.surface() to generate the matrix of
predicted values. These functions use many of the same inputs as the
Krig() function in R. My problem is that the output is a symmetrical
matrix of dimension NxN, however, because R outputs an NxN matrix it
necessarily results in having a rectangular grid cell (e.g., x dimension
is 50 and y dimension is 30) for any input data set whose spatial extent
is not square.
My question is; does anybody know how to import a rectangular grid from an
ASCII raster file into ArcGIS using something other than the AsciiToGrid
function in ArcGIS, which only allows for square grids?
Thanks in advance for any help,
Matt
