NAME

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

v.mkgrid help

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

"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

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

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

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
