[OSRS-PROJ] Re: Majordomo results: Hi

I have one more application which converts the WGS84 lat/long to state plane 
coordinates in NAD27. The program I have is pathfinder tools (pftools.ocx) . 
The output I get from the pftools match with my map coordinates.

   I am curious to compare the results from cs2cs and pftools.

Thanks,
Srinivas.

Srinivas -

Duncan (and Frank) have already given you the easiest answer to get the 
correct results.  However, the values you give as "desired output" don't 
seem correct.  How are you getting the values that you think are the correct 
answer?

Hi,

   Yes. I copied the command line correctly. I am trying to convert the 
WGS84
to NAD27:2113 (michigan south ).

    I keyed in the following input

lat = 42.329867
lon = -83.057190

The desired output should be xy =2345029.400940,305024.741194

and the program gives *\t* output. Please let me know if i keyed in the
wrong values.

I appreciate your quick response.

Thanks,
Srinivas.

Srinivas -

Is that command line copied correctly?  I just took a quick look, and you
seem to be trying to use the Michigan South Zone SPCS.  You should provide
the longitude of the grid origin and the false easting of the CS (the false
northing is 0) by adding these parameters to the output CS definition:

       +lon_0=-84.366666667 +x_0=4000000

Let us know if that's not the problem.  If you still have trouble, please
confirm which SPCS you're trying to use, and give us some example input and
output coordinates.

Hi,

     I am trying to convert the GPS data in to state plane coordinates. I am
using cs2cs executable on windows to convert the data. Here is what i did

      cs2cs +proj=latlong +datum=WGS84 +to +proj=lcc +lat_1=42.100000000
      +lat_2=43.666666667 +lat_0=41.500000 to_meter=0.3048006096

     When i enter the lat/long , i got erronous output. I am not sure if i 
am
doing it correctly. But i would like the output in x,y,z when keyed in
lat/long.

     I would appreciate if some one can help me out. Please let me know if I
am not clear.

Thanks,
Srinivas.
