NAME

v.mkgrid - Creates a (binary) GRASS vector map of a user-defined grid.

SYNOPSIS

v.mkgrid
v.mkgrid help
v.mkgrid [-q] map=string grid=rows,columns position=string [coor=x,y] [box=width,height] [angle=float]

Flags:

-q
Quiet; No chatter

Parameters:

map=string
name of vector map
grid=rows,columns
number of ROWS and COLUMNS in grid
position=string
Where to place the grid:
region - current region
coor - use 'coor' and 'box' options
Options: region,coor
Default: region
coor=x,y
lower left EASTING and NORTHING coordinates of map
box=width,height
WIDTH and HEIGHT of boxes in grid
angle=float
angle of rotation (in degrees counter-clockwise)
Default: 0

DESCRIPTION

v.mkgrid will create a vector map representation of a regular coordinate grid.

NOTES

This is NOT to be used to generate a vector map of USGS quadrangles, because USGS quads are not exact rectangles.

EXAMPLE

Make a 4x3 grid, cells 20km a side, with lower left corner at 2716500,6447000:

v.mkgrid map=coro_grid grid=4,3 position=coor coor=2716500,6447000 box=20000,20000
