gis:raster-world-envelope

gis:raster-world-envelope RasterDataset x y

Reports the GIS envelope needed to match the boundaries of NetLogo patches with the boundaries of cells in the given raster dataset. This envelope could then be used as an argument to set-transformation-ds.

There may be more cells in the dataset than there are patches in the NetLogo world. In that case, you will need to select a subset of cells in the dataset by specifying which cell in the dataset you want to match with the upper-left corner of the NetLogo world. Cells are numbered from left to right, and from top to bottom, beginning with zero. So the upper left cell is (0, 0), and the bottom right cell is (gis:width-of dataset - 1, gis:height-of dataset - 1).
