NAME

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

KEYWORDS

vector

SYNOPSIS

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

Flags:

-q

Quiet; No chatter
--overwrite

Allow output files to overwrite existing files
--verbose

Verbose module output
--quiet

Quiet module output

Parameters:

map=name

Name for output vector map
grid=rows,columns

Number of rows and columns in grid
position=string

Where to place the grid
Options: region,coor
Default: region
region: current region
coor: use 'coor' and 'box' options
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
