hello, Could you be so kind to tell me how to find the WKT including the parameters toWGS84 of the MGRS system? Many thanks in advance for your time and your help, Best regards, Laura
On its own, MGRS doesn't have a well-defined datum/geographic coordinate system. It's most likely using WGS84, but could be based on a bunch of different GCSs. As long as the data is using a GCS that uses the "new" style MGRS (see note below), it would depend on the accuracy as to whether it matters. If you're okay with meter accuracy--10 digits after the letters--then you could just define it as WGS84 or other GRS80-based GCS and not worry about a toWGS84 transformation.
Note: The old style MGRS is used with some GCS that use Bessel 1841, Clarke 1880, Clarke 1866, and so on.
You mean the military grid ref sys ?? Military grid reference system but it is base on UTM?
thanks for the quick reply. Yes, I mean the military grid reference system.
I am using an ESRI Connector of one IBM Application called Analysis Notebook, when displaying entities stored in MGRS it says the datum is not well specified. The user guide refers to the fact that you need to add the WKT of all the Coordinates Systems utilized and their toWGS parameters. That is why I thought I need the WKT for the MGRS.
Thanks again and best regards,
Many thanks Melita!
