Parcel Fabric, Ne doit pas intersecter ou toucher l'intérieur

Question

<\/HEAD>Nous testons avec un groupe d'environ 1300 parcelles pour migrer vers le Parcel Fabric. Lorsque nous validons la topologie, nous recevons environ 2000 erreurs de "ne doit pas intersecter ou toucher l'intérieur" pour les lignes de parcelle. Les parcelles ont été initialement créées dans MapInfo et nous avons converti un shapefile. Quelqu'un aurait-il des recommandations sur la manière de résoudre cette quantité d'erreurs de manière raisonnable ? Notre comté compte plus de 90 000 parcelles et si 1300 parcelles entraînent 2000 erreurs, je suis vraiment <\/EM>inquiet de ce que 90 000 parcelles vont générer. <\/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).
