 Creates a temporary map.  Sets center of map to (-114,51) and scale to 1:50000.  Turns on layers d5d01111 and d5d01118.  The visible layers are rendered as a 500 by 500 PNG image.  No selection is defined or drawn.
 === Technical Notes ===
+== !GetVisibleMapExtent ==#GetVisibleMapExtent1.2
+=== Overview ===
+Returns the visible map extent for the map specified by SESSION and MAPNAME.  During the call, the map state can be modified by additional parameters such as SETVIEWCENTERX and SETVIEWSCALE. This API is typically called before [##GetDynamicMapOverlayImage1.2 GetDynamicMapOverlay] to set map state.  The returned XML document has the following format:
+{{{
+<?xml version=\"1.0\" encoding=\"UTF-8\"?>
