  * 	\li [Proj:][D][D]Dmm.mm.. N/S [D][D]DMM.mm... E/W - lat/long (WGS 84), integer degrees (DD) and minutes as decimal fraction (MM), Proj must be "geo" or absent
  * 	\li [Proj:][-][D]D.d[d]... [-][D][D]D.d[d] - long/lat (WGS 84, note order!), degrees as decimal fraction, Proj does not matter
  * 	\li utm[zoneinfo]:[-][D]D.d[d]... [-][D][D]D.d[d] - UTM coordinates, as decimal fraction, with optional zone information (?)
  * Note that the spaces are relevant for parsing.
