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
