The grid tool (GridToos.mbx) converts grid files to MapInfo grids (*.mig). This tool replaces the previous DEM2Grid Map Basic utility. The grid converter converts grid files using the available grid handlers. By converting grids to MIG format, you may be able to get better performance then using the direct read grid handlers. It creates a grid from points in a table and provides and Info tool that display x, y, and z values at the cursor location.
