Dear all

Does vtk read and plot data of grid file with an
extension grd.

Could I have any help to built a vtk reader of this
file.

my "file.grd" has the following parameters:

numbercols         2681
nrows         2361
xllcorner     125987.50
yllcorner     19987.50
cellsize      25
NODATA_value  -9999

-  ncols refers to the number of columns in the grid
and xxxxx is the numerical value
*nrows xxxxx 

- nrows refers to the number of rows in the grid and
xxxxx is the numerical value


- xllcorner refers to the western edge of the grid and
xxxxx is the numerical value


- yllcorner refers to the southern edge of the grid
and xxxxx is the numerical value


- cellsize refers to the resolution of the grid and
xxxxx is the numerical value


- nodata_value refers to the value that represents
missing data and xxxxx is the numerical value. 


Anyhelp it is welcome.
