[Freegis-list] tool to find out lat/lon --> UTM

[Cere Davis]

Hi everyone,

I have sort of a basic GIS question that doesn't appear to be all that
obvious to me.

I am using the proj4 tools in linux to find at utm X-Y zone value for a
given lat-lon value.  I have played around with it for a bit and I am
suprised to find that proj requires me to input a default easting zero
value (such as +lon_0=120w) in order to get meaningful x-y data for my
zone.  To me this seems like redundant information.  If I give my lon_0
value then I allready know what zone I am in basicly so this is not very
usefull to me.  I suppose I could do some pre math and make some
assumptions about the quadrant that my lat/lon value are in to find the
lon_0 value before I send arguments to Proj but...  Is there any tool that
just allows me to type in a lat/lon and returns a x-y and zone value?

Thanks,
