[Proj] cs2cs syntax help

[nicolas david]

Hi Szilard

concerning you first point "using the command properly"
a) first you have to use input telling if your coordinate are north/south
and east/west. so transform
26d25'55" 126d15'04"  to 26d25'55"S 126d15'04"E
b) you need to specifie that you want UTM51 south and not utm51 north by
using the +south parameters
spatialreference.org is a very good ressource for finding this kind of
stuff : http://www.spatialreference.org/ref/epsg/32751/
cs2cs +proj=latlong +datum=WGS84 +to  +proj=utm +zone=51 +datum=WGS84 -r
