Parcel Fabric, darf sich nicht schneiden oder das Innere berühren

Question

<\/HEAD>Wir testen mit einer Gruppe von ungefähr 1300 Parzellen, um sie in das Parcel Fabric zu migrieren. Wenn wir die Topologie validieren, erhalten wir ungefähr 2000 Fehler vom Typ "darf sich nicht schneiden oder das Innere berühren" bei den Parzellengrenzen. Die Parzellen wurden ursprünglich in MapInfo erstellt und wir haben eine Shapefile konvertiert. Hat jemand Empfehlungen, wie man diese Menge an Fehlern auf vernünftige Weise beheben kann? Unser Landkreis hat über 90.000 Parzellen, und wenn 1300 Parzellen zu 2000 Fehlern führen, bin ich wirklich <\/EM>besorgt darüber, was 90.000 Parzellen ergeben werden. <\/P><\/BODY><\/HTML>

You can also use the Integrate geoprocessing tool, which makes shared boundaries coincident.

Did you use the polygon to line tool or the feature to line tool when simplifying your original parcel polygons?  I was using the feature to line tool and getting many errors like you because of duplicate lines that create topology errors.  Once I switched to polygon to line tool and checked the identify box the duplicate lines were gone and so were the typology errors

Just a general comment - when you import a shapefile to a geodatabase that has features created in geodatabase format and then run topology, there will be many slivers generated on curves due to the differences in how shapefiles store curves versus geodatabases.  At the City where I am at we encounter this often when updating our parcel data, as our "older" parcels were originally put into SDE from a process many years ago that involved shapefiles.  Our current process brings in newer parcels from a geodatabase, but when they adjoin parcels that were originally from shapefiles there are many tiny slivers.  So lots of errors, which is not unexpected (though certainly not desirable).
