[mapserver-users] Shapefiles - different formats?

[Janet Ciavarelli]

Hi Ed,
   I see what the difference is now. I went into ArcCatalog and created an empty shapefile, and I looked in explorer. It creates 4 files! Not just the 3 files that it used to use (.shp, .shx, .dbf).

I've attached all the four files. So that explains why ArcView 3.2 can open the file though. Cause it finds the 3 files and just ignores the 4th. But ArcMap 8 wants all 4 files. The 4th file is a .prj file. I will have to find out what's in it and get my script to create that as well. Also, maybe that utility you advised me to grab will create it. I will check when I get time which my be a long time from now. 

Thanx for your help. Janet.

Can you create an empty point shapefile in 8.1 and send that to me, too?
I don't have 8.1, but I can take a look at the shapefile to see if
there's anything different.

Yes, same symptom even with records added.

Do you get the same symptom when you add records to the shapefile?

Hi Ed,
   Here's a copy of the shapefile. BTW, it is an empty one but it should
be successfully able to open empty shapefiles as well. We've tried it
with both empty and un-empty ones and get the same results: it opens
find in AV 3.2 but errors out in AV 8.1

I certainly expect 8.1 reads 3.2 shapefiles (at least, in general).
Perhaps it's more likely that you're creating a slightly out-of-spec
shapefile that's being tolerated by 3.2, but 8.1 is being fussier about.

There's a tool called shpfix in the GDAL distribution that might
possibly help clean up the file.  If you'd like to email me the
shapefile I'll take a look at it.

Sort of off topic, but thought I'd ask anyways in case anyone knows. I
have written a perl/mapscript to create a shapefile. I can view the
shapefile in ESRI  ArcView 3.2 fine. But when I try to view it in ESRI
ArcView 8.1, I get an error. Is anyone out there aware of any
differences between shapefile formats between different products?

Janet.
