Basic function to create a geotransform as used by GDAL.

geo_transform0(px, ul, sh = c(0, 0))

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
