[adegenet-forum] Coordinates and distances in sPCA

[Tagliamonte,Massimiliano S]

I am not sure the previous message was sent correctly, so I will try again:

If I remember correctly,  you should convert your coordinates to the utm system. I do not have access to my old scripts right now, so you'll have to look for some converter package. Let me know if you need any more help with it.

Regards,
Max

Subject: [adegenet-forum] Coordinates and distances in sPCA

Dear All,

I've searched tutorials and internet to find what coordinate system
should be used in sPCA but found no information. I checked data from
Rupica, but could not figure out what cooridinate system it is. When I
used regular WGS84 coordinates the distances between points are
expressed in strange units of approximatelly 78 km but are consistent
along north/south and east/west distances (however I did not check them
in detail).

Where should I search for such information?

Cheers,

Maciek
