Hi everyone!  I'm new to R.  I'll try using it for some Kriging.  My aim in the short-term is to convert my 2300 stations database from lat-long to UTM.  This network of stations goes from Virginia to the south, to Montréal to the north, east coast to Michigan in the west.  So, I have a lot of UTM zones to consider.  

 

Reading the archives, I've seen this formula to calculate the zones, based on lat-long coordinates :

 

UTM = floor((lon + 180) / 6) + 1

 

So, if I understand correctly, I need to run this formula on each station to get their zone, abnd then I use something like convUL ?
