Hi Brent, Yeah... I was shuffling the X and Y around to see if it make a different, but either combination doesn't seem to work. I check the PROJ_LIB environment variable, it wasn't set. Setting the variable in Solaris and Apache to /usr/local/share/proj doesn't seem to work.
Executing: # proj +proj=lcc 79.725 43.715 (input) 5619844.75 7781484.62 (output) 43.715 79.725 (input) 1266934.34 10025427.15 (output) Does that confirm Proj4 is working correctly? I been stuck here for awhile... This going to haunt me if I can't figure out what's wrong...

Try changing it to x='X' y='Y'. Although I don't know why it would work on Windows but not Solaris. You may want to confirm your Proj installation is working correctly on Solaris by converting a few coordinates using the proj command on the Solaris command line. I think you may need to ensure the PROJ_LIB environment variable is set to the location of the Proj epsg file. Brent Fraser GeoAnalytic Inc.

Those large number in the .csv file are added because I wanted to test the plotted points... One thing that I find very puzzling is that we have tried the map-server using two different platform: - Windows XP - Solaris SPARC / UNIX Both platform use almost the exact config.map file and .csv file But for some reason, we did not have any problem on the Window Platform... All the points are plotted with little trouble... but then again, in Windows the map-server was package very nicely in a binary form. Also, I pay very close attention so case-sensitive issues (i.e. epsg V.S. EPSG). Could the problem be some other case sensitivity issue in Soalris/UNIX? Thank you so much for your help so far. Much appreciated Toan -----Original Message----- From: Brent Fraser [mailto:[EMAIL PROTECTED] Sent: December 10, 2007 2:26 PM To: Tran, Toan (MCYS); [email protected] Subject: Re: [UMN_MAPSERVER-USERS] Data Plotted at Wrong Location Toan, Looking at the snippet of the csv file you provided below, you've got some coordinates in a Geographic (decimal degrees of latitude and longitude) and some in a projected system (meters LCC?). Mapserver usually allows only one coordinate system definition per input file, so this is not valid. They need to be all Geographic coordinates or all projected. And check your extents in the map file. Would they cover the points in the csv file? It might be helpful if you included your map file. Brent Fraser GeoAnalytic Inc.

I am new to Map Server... I have: PROJECTION "init=epsg:42304" END inside both my top-level MAP and LAYER definition. I try Adding/Changing (Is this what your meant?) inside my Layer definition... All the points that as plotted before are now gone. PROJECTION "init=epsg:4269" END The proper location is still not plotted. Something I am doing incorrectly? Thank you so much for your help.

Add a PROJECTION object to the csv file's LAYER definition. For example, if the input data in the csv file is NAD83: LAYER csv PROJECTION "init=epsg:4269" END : Brent Fraser GeoAnalytic Inc.

My data are in decimal degree stored in a CSV file. But when the map was draw, all the points are plotted very closed together. I suspect that for some reason, the map-server is plotting the data as meter/or any other unit instead of degree decimal. I used this PROJECTION in both my top-level MAP and proper layer, with UNITS METERS: PROJECTION "init=epsg:42304" END I added this for the /usr/local/share/proj/epsg file because it wasn't there after I installed the Projection Library: <42304> +proj=lcc +lat_1=49 +lat_2=77 +lat_0=49 +lon_0=-95 +x_0=0 +y_0=0 +ellps=GRS80 +datum=NAD83 +units=m +no_defs no_defs <> Is it enough to simple add the above epsg code??? Changing UNITS METERS to UNITS DD in my map file doesn't help either. Here are some sample DATA: <<img.GIF>> Desc,,X,Y "5",79.725833,43.715361 "6",81.000107,43.368512 "7",-78.347276,44.301459 "8",,81.332038,48.47381 "9",79.68955,43.4662 ...
