Tips for using the IMAPS Viewer

  • You can change the map area by zooming in (+) or out (-) using the magnifier icons.
  • In the layer list, the checkbox to the left of the layer name turns the layer on or off.
  • If you have a large screen, the viewer speed may be reduced. Shrinking your browser window will increase the Viewer speed.
