He means giving the projections with the actual strings which are also hidings behind the epsg codes, for example this means the same as epsg:2393 PROJECTION "+proj=tmerc +lat_0=0 +lon_0=27 +k=1.000000 +x_0=3500000 +y_0=0 +ellps=intl +towgs84=-90.7,-106.1,-119.2,4.09,0.218,-1.05,1.37 +units=m +no_defs" Projection strings are slower to write into mapfile but for Mapserver they are faster to execute because these is no need to jump to projection library file. If you have MS4W installation you can find the strings to use from D:\ms4w\proj\nad directory, most of them from file names epsg. -Jukka Rahkonen-
