  • 1.  Add support for coordinate systems PNG94/PNGMG94 zones 54, 55 and 56

    Posted 02-21-2018 06:26

    I would like the next Mapinfo to include the latest coordinate systems for Papua new Guinea. i.e. PNG94/PNGMG94 zones 54, 55 and 56.

    Thanks

    I went digging to get more information on implementing this request. I found the Datum info which suggests to me there are three different Datums that can be used here depending on location. These datums obviously correlate to a particular TM zone (54, 55, and 56), but I am not certain which datum goes with which zone.

    I provided the info below you can use to create these mapinfow.prj entries with a custom datum. If you create the entries and try them out to make sure they are correct, I would be happy to include them in a version of MIPro.
