Hi QGIS Developers :-)<br>
<br>
I asked some help on QGIS support, but they told me that I don't ask
my question at the right place, and that I should go througth
developers email list.<br>
That's why I'm here. So let me explain what's going on.<br>
<br>
I developped an application with a class able to read data from an
Oracle database with MapXtreme (MapInfo), and convert them in
Shapefile.<br>
This class follows the ESRI specifications from here :
<a class="moz-txt-link-freetext" href="https://www.esri.com/library/whitepapers/pdfs/shapefile.pdf">https://www.esri.com/library/whitepapers/pdfs/shapefile.pdf</a><br>
You can find in attach 2 samples that I tried to open in QGIS :<br>
- 4480___S12_060_4 : there is only one polygon, but it is not
displayed on the map<br>
- 4480___327550 : there are 8 polygons in this one, and all of them
are well displayed<br>
The strange thing is that the polygon from "4480___S12_060_4" is
common with "4480___327550", but in one case it is not shown, and in
the other case it is shown.<br>
I have no problem when I open these files with MapInfo.<br>
I don't have ArcMap to check on this side.<br>
The support told me they were not able to open my files with SAGA,
but I downloaded SAGA GIS 2.2.3 and was able to open the file
without any issue...<br>
<br>
According to QGIS support, it looks like an issue in my creation
algorithm, but I really don't see what's wrong, it seems to follow
well the ESRI specifications.<br>
I'm not a "GIS expert", so maybe some of you could help me to
discover what's wrong.<br>
Or if you have any GIS tool that can tell me what's not correct in
my shapefile, it could really help me.<br>
<br>
You can find in attachment the source code of my class in VB.Net.<br>
<br>
Many thanks !<br>
<br>
Regards,<br>
<br>
