Hi,
I wish to plot several points in Canada, but the problem is that the
points are plotted at the wrong location. My data are in decimal degree
stored in a CSV file. I am guessing that Map Server plots the points in
meters instead of degree.
I used this in my map layer:
PROJECTION
"init=epsg:42304"
END
I added this for epsg:
<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 <>
I try changing:
- <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=dd +no_defs no_defs <> ....
this causes a msProcessProjection(): Projection library error. unknown
unit conversion id error
- UNITS METERS to UNITS DD in my map file, but that doesn't help.
Sample DATA:

"AAAAAAAAAAAAAAAAAAAAAAaaaaaa19",0,200000
"AAAAAAAAAAAAAAAAAAAAAAaaaaaa20",0,220000
"AAAAAAAAAAAAAAAAAAAAAAaaaaaa21",0,240000
"AAAAAAAAAAAAAAAAAAAAAAaaaaaa30",0,300000
"AAAAAAAAAAAAAAAAAAAAAAaaaaaa31",10000,300000
Any help is much appreciated
Thanks
Toan
