# CreateFloatRaster

.

### Calling Sequence

    handle_ras = CreateFloatRaster ( ncols , nrows , cellsize , xll , yll , NODATA_value , LL [, name] )

### Arguments

ncols

  integer: number of columns (X-dimension) of the raster

nrows

  integer: number of rows (Y-dimension) of the raster

cellsize

  float

xll

  flaot: X coordinate of the lower-left pixel. If LL = 0, then xll is itself the coordinate of the lower-left corner of this pixel (xllcorner) ; if LL = 1, it is the coordinate of the center of this pixel (xllcenter).

yll

  float: Y coordinate of the lower-left pixel. If LL = 0, then yll is itself the coordinate of the lower-left corner of this pixel (yllcorner) ; if LL = 1, it is the coordinate of the center of this pixel (yllcenter).

NODATA_value

  float

LL

  character string: 'corner' or 'center', specifying the convention for referencing the lower-left pixel (x/y/llcorner or x/y/llcenter).

Name

  optional: character string

handle_ras

  integer: handle on the newly created raster

### Description

Allocates a single-precision floating point raster (FloatRaster structure) with specified dimensions and georeferencing.

Returns a handle on the object created.
