  • The Enter AMG Coordinates tool has been updated to allow the user to specify the original datum of the AMG coordinates. These may be AMG66, AMG84, or current MGA94. The AMG coordinates are then correctly converted to WGS84 latitude & longitude used by GreatCirc. Note that GreatCirc only displays latitude & longitude to 1 second accuracy.

Combined with the ability to load and merge data from KML, GPX, AMG and MapList files, this provides a limited capability to convert files in these other formats into a KML output file for sharing with Google Earth users.
  • While GreatCirc does not use altitude information from GPX or KML files, this data is now preserved in case the user saves to a KML output file in Batch Mode.
  • If there is a problem loading a map data file in Batch Mode, now only the data from the offending file is lost, and any previously loaded data is retained.
  • New items in the Options menu of Batch Mode allow the user to control display of labels and place markers.

  • In Batch Mode, user can now change font and font size used for text labelling.
  • In Batch Mode, when the map is zoomed, the user can now use keyboard arrow keys to move the view around.

  • GreatCirc now warns the user if one of the selected points will not be visible when switching to Mercator projection (eg. if too close to poles).
