Info

Displays and hides the Header Info window for the DEM.

The Header Info window displays meta-data for the DEM, including quadrangle name, size, location, resolution, etc. The "Grid W Edge" and "Grid N Edge" values are the coordinates of the center of the upper left elevation sample. MacDEM uses this as the origin of the DEM.

When this window is visible the Copy command in the Edit menu is available to copy this data to the clipboard.

An example of a Header Info window is shown below.
