[Mapserver-users] Extent units

[Mario Servin]

Hi,
    I was playing with the demo.map and now I want to use my own shapefiles
but I do not know the EXTENT of my map..... I downloaded shapelib from the
Internet and with shpinfo.exe I get:
Info for calles.shp
Polyline(3), 338 Records in file
File Bounds: (   -71.53179836,   -41.29253644)
        (   -71.14854968,   -41.04421467)

Then there is some unknown error . I do not know how to use these values as
I never saw something like this values (GG.GGGGGGG) in .map file. Can
anybody help me?
