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 ...
