Update of bug #53422 (project octave):

                  Status:               Confirmed => In Progress            


Follow-up Comment #9:

A progress report:

Upon close inspection, shapewrite's code for "Point" geometries; AFAICS
conforms exactly to the specs in
Indeed, I found that the utility program shapechk.exe [*] rather screws up the
.shx file.

However, along the way I fixed a bug in dbfwrite.m (io package), it prepended
a space to text attributes.
I also adapted shapewrite.m to always write a .dbf file.

As to your remark in comment #4 that shaperead.m produces a different struct
than you wrote with shapewrite.m:
Note that the Point geometry has no BoundingBox field - it isn't in the specs,
see URL above.

With these changes I'll try again with ArcGIS.
