Perceelstructuur, mag niet snijden of het interieur raken

Question

<\/HEAD>We testen met een groep van ongeveer 1300 percelen om te migreren naar de Parcel Fabric. Wanneer we de topologie valideren, krijgen we ongeveer 2000 fouten van "mag niet snijden of het interieur raken" voor de perceellijnen. De percelen zijn oorspronkelijk gemaakt in MapInfo en we hebben een shapefile geconverteerd. Heeft iemand aanbevelingen over hoe deze hoeveelheid fouten op een redelijke manier op te lossen? Onze county heeft meer dan 90.000 percelen en als 1300 percelen resulteren in 2000 fouten, ben ik echt <\/EM>bezorgd over wat 90.000 percelen zullen opleveren. <\/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).
