Setting Map Size

The map size can be set as follows:

• The default size on start up is set on the options form, on the Maps tab and the Vector maps tab.
• For DEM maps there are two distinct options:
  • Set a maximum size, with the defaults size button (Maps tab).  The map will be smaller than this in one dimension, to keep proper scaling.  This will be the default when the program first opens, and the size will be a fraction of the screen size so that the DEM fills most of the screen without any scroll bars.
  • Set a zoom factor, with the check box and edit box (Maps tab). 100% is 1:1 view, 50% is every other column in every other row, and so on.  If the data spacing is unequal, such as in a lat/long DEM, this will be approximate (but reproducible).
• You can adjust the size when a map is open with the Zoom in (makes the map larger with the same coverage area), 1:1 view, and Zoom out (makes the map smaller with the same coverage area), buttons on the map toolbar.
• The Modify, Map size menu choice lets you change the map size.
• The File, Match other maps menu choice lets you have all the open maps have the same coverage area and scaling, if they cover the same area..

If the size is too big to fit on screen, you will have scroll bars to move around and navigate.
