Parcel Fabric, nesmí se protínat ani dotýkat vnitřku

Question

<\/HEAD>Testujeme skupinu přibližně 1300 parcel pro migraci do Parcel Fabric. Při ověřování topologie obdržíme přibližně 2000 chyb "nesmí se protínat ani dotýkat vnitřku" u parcelních linií. Parcely byly původně vytvořeny v MapInfo a převedli jsme shapefile. Má někdo nějaká doporučení, jak rozumně vyřešit toto množství chyb? Náš okres má přes 90 000 parcel a pokud 1300 parcel vede k 2000 chybám, opravdu se <\/EM>obávám, co vrátí 90 000 parcel. <\/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).
