OS Grid Builder- Create grids at a range of resolutions in MIF/MID and Shapefile formats

OS Grid Builder creates attributed grids at 100km, 20km, 10km, 5km and 1km resolutions. Each grid cell is attributed with tile name and lower left and top right coordinates. Each grid covers a 100km grid square.


Grids can be created as MapInfo Import (MIF/MID) files or Shapefiles for use in any GIS software. Multiple grids can be created in one operation (each 100km block is saved as a separate file). Easier and quicker than creating grids in your GIS program!
