beginner: How to use shapes files

[Julien Buratto]

A person told me to use MapInfo to convert my .TAB MAP ID DAT files to
shapes, so I did use the mapinfo "Universal translator" to convert to
ESRI shapes.

I don't know how to:
- get the EXTENT values
- keep on I'm halted now

The 4 files 302010.MAP TAB ID DAT are now:

-rw-r--r--  1 root root  448977  1 mar 12:09 302010_point.dbf
-rw-r--r--  1 root root     409  1 mar 12:09 302010_point.prj
-rw-r--r--  1 root root   41288  1 mar 12:09 302010_point.shp
-rw-r--r--  1 root root   11868  1 mar 12:09 302010_point.shx
-rw-r--r--  1 root root  696332  1 mar 12:09 302010_polyline.dbf
-rw-r--r--  1 root root     409  1 mar 12:09 302010_polyline.prj
-rw-r--r--  1 root root 2740308  1 mar 12:09 302010_polyline.shp
-rw-r--r--  1 root root   18356  1 mar 12:09 302010_polyline.shx
-rw-r--r--  1 root root  227852  1 mar 12:09 302010_region.dbf
-rw-r--r--  1 root root     409  1 mar 12:09 302010_region.prj
-rw-r--r--  1 root root  356176  1 mar 12:09 302010_region.shp
-rw-r--r--  1 root root    6068  1 mar 12:09 302010_region.shx
-rw-r--r--  1 root root  466496  1 mar 12:09 302010_text.dbf
-rw-r--r--  1 root root     409  1 mar 12:09 302010_text.prj
-rw-r--r--  1 root root   22332  1 mar 12:09 302010_text.shp
-rw-r--r--  1 root root    6452  1 mar 12:09 302010_text.shx

I've then tryed to create a map file for one of these, the 302010_region

NAME DEMO
SIZE 800 300
IMAGECOLOR 255 255 255
EXTENT 0 0 5000000000 50000000000

LAYER
DEBUG ON
  NAME "302010_region"
  TYPE POLYGON
  STATUS DEFAULT
  DATA "302010_region.shp"
  CLASS
    NAME "Province"
    STYLE
      OUTLINECOLOR 120 120 120
      COLOR 255 255 0
    END
  END
END # layer
END

but I get a white image and I still don't know how to set the EXTENT
values, my ogrinfo are:

Can anyone give a hint on how to procede ? I'm getting stuck in seeing
white gifs  :-D

Thanks
