VFK: Generated invalid parcel "banana" geometries

[seidlmic]

OGR VFK driver ver. 2.4.4 built on Debian from source generates invalid geometries at least for PAR layer(table) in situations called "banana" polygon. Instead of creating polygon with hole that touches exterior ring at one point it creates polygon in "banana" shape or even self intersection polygon type. The invalid polygon can be detected with ST_IsValid() function after importing into Postgis database.

@seidlmic Can you send me a sample data to reproduce it?

Hi, I think you can use any data you have. In 54 imported cadastral districts ST_IsValid() found 154 invalid geometries. This is the case you import SGI and SPI VFK file into one SQLite tmp DB when final target is Postgis. I will send some data directly to you.
