[Qgis-user] Problem Noticed with QGIS

[Richard McDonnell]

Hi All,
Im currently running the Following


QGIS version


3.28.1-Firenze


Qt version


5.15.3


Python version


3.9.5


GDAL/OGR version


3.6.0


PROJ version


9.1.0


EPSG Registry database version


v10.074 (2022-08-01)


GEOS version


3.11.1-CAPI-1.17.1


SQLite version


3.39.4


PDAL version


2.4.3


SpatiaLite version


5.0.1


QWT version


6.1.6


QScintilla2 version


2.13.1


OS version


Windows 10







I have the following issue.

As part of our Data verification Processes, we require that our data arrive as Singlepart Geometries.
We run the Check Geometries Tool and it flags the data as Geometry Type Error. So I run the Multipart to Singlepart tool and....well that's where the problem is...

Its two parts...


1.       If I use the option [Create temporary Layer] it produces a Singlepart Geometry as Expected, If I save the output to a File, the resultant geometry is stated as Polygon (MultiPolygon) Its the same for Linestrings also.



2.       When the New "corrected" layer is passed through the Check Geometries Tool, it flags it as a Geometry Type Error, even though I know its fixed, as I can validate it in an external tool.

Now I did find this.. https://github.com/qgis/QGIS/issues/50720 which flags the same issues, but states that its down to the Shapefile Specification.

Is there a work around for this??

Regards,

Richard
