Wrong extents after dynamic shapefile generation

Fri Jan 28 05:11:53 EST 2005

Hi List,

i encounter a strange problem when i generate a (polygon) shapefile on
the fly on a windows xp box running php mapscript 4.4.1 (windows
binaries from
http://maptools.org/dl/mapserver-4.4.1-win32-php4.3.7.zip).
The creation of the shapefile acts without any problems but when i
execute 'ogrinfo -so' on this file the value of maxy is completely
wrong.
When i take a closer look at the single features of the shapefile
everything looks reasonable to me. So i assume that the generation of
the header entry with the extents did something wrong. Running the same
script with the same data on linux the extents of the shapefile as looks
expected.
Attached you can find the output of ogrinfo. What is going wrong here?
Is this a bug?
If you need further information please let me know.

Many thanks
Nicol
