Bazı çok büyük çokgen katmanlar üzerinde bazı işlemler yapmaya çalışıyorum. Ancak ben gibi çeşitli geometri hatalarıyla karşılaşıyorum:

Burada önerilen işlevi denedim: https://trac.osgeo.org/postgis/wiki/UsersWikiCleanPolygons
geometrileri temizlemek için kullandığım kod:
UPDATE public.mytable
SET geom=cleangeometry(geom);
Sonuçla beraber:
ERROR: GEOSisSimple: IllegalArgumentException: This method does not support GeometryCollection arguments
ve ayrıca
UPDATE public.valid_mytable
SET geom=ST_MakeValid(geom);
Bu işe yarar, ama sadece geometri sütunumu ilk önce geometriye değiştirirsem
ALTER TABLE public.mytable ALTER COLUMN geom SET DATA TYPE geometry;
Bu da beni artık diğer işlevlerimle çalışmayan bir masaya bırakıyor!
ERROR: Relate Operation called with a LWGEOMCOLLECTION type. This is unsupported.
Geometriye (MultiPolygon) geri sütunları değiştirmeyi denedim
ALTER TABLE public.my_table ALTER COLUMN geom SET VERİ TÜRÜ geometrisi (MultiPolygon);
Ama bu başarısız oluyor
ERROR: Geometry type (GeometryCollection) does not match column type (MultiPolygon)
PostGIS in Action (Second Ed) http://www.manning.com/obe/ üzerinden geçmeyi denedim ama sadece geçersiz geometrileri bulmak için işlevleri bulabilirim, ancak veri setim bunu manuel olarak düzeltmek için çok büyük, gerçekten Onları otomatik olarak düzelten bir şeye ihtiyacım var.
ST_MakeValid () çalışmayı denediğimde, sorun çokgenleri izole edebildim, sonucu alıyorum:
ERROR: Geometry type (GeometryCollection) does not match column type (MultiPolygon)
********** Error **********
ERROR: Geometry type (GeometryCollection) does not match column type (MultiPolygon)
SQL state: 22023
Geometri sütunumda tip kontrolü yaptım ve tipin "ÇOKOLOJİ" olduğunu söyledi.
