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
