[mapserver-users] MS 3.5 Trouble getting a POLYLINE shape file to display

[Stephen Woodbridge]

Steve,

Use:
  shpdump <shp file> | head

it will tell you on the first line what type of data is stored in the
shape file.  If you want to change it's type you will probably have to
write some Perl or C code to read the shape file and write a new one,
using shplib
