Arguments

px

pixel resolution (XY, Y-negative)

ul

grid offset, top-left corner

sh

affine shear (XY)

Value

vector of parameters xmin, xres, yskew, ymax, xskew, yres

See also

geo_world0() which uses the same parameters in a different order

Examples

geo_transform0(px = c(1, -1), ul = c(0, 0))
#>  xmin  xres yskew  ymax xskew  yres 
#>     0     1     0     0     0    -1
