[mapserver-users] world vector shorelines shpfile - convert meters to DD in mapfile

[Gregor at HostGIS]

> The problem is that this shapefile uses units which are in meters, and 

Two solutions:

a) Use a PROJECTION block like this, to tell MapServer to reproject the 
data on the fly:

PROJECTION
    "init=EPSG:123456"
END

b) Reproject the data into DD using ogr2ogr:

ogr2ogr -t_srs EPSG:4326 -s_srs EPSG:123456 dd.shp utm.shp


Note that reprojection on the fly isn't a fast operation, so if your 
data is large or there's no need for it to be in meters (say, distance 
measurements between coordinates) you may prefer Option B.
