Title: How to add custom datum?
Post by: fvoska on November 08, 2014, 12:29:08 AM
In OruxMaps for my Android Tablet I see a long list of available datums. However, I need a very specific datum which isn't listed. How can I set it up manually? Can it be done in application or do I have to change map files somehow?



Settings I need for my datum are:

  • Longitude origin: E 015°00.000'
    • Scale: 0.999
    • False Easting: 5500000
    • False Northing: 0.0

    • DX: +675
    • DY: -205
    • DZ: +475
    • DA: +740
    • DF: +0,0001004


    I use these settings for my Garmin GPS and it works fine. How can I adjust this in OruxMaps for Android?



    All help is appreciated, thank you :)

    • Hi,



    those values are parameteres for a datum and for a projection.



    which datum (name) and projection do you want to use?
