Parcel Fabric、内部と交差または接触してはならない

Question

<\/HEAD>約1300のparcelのグループでParcel Fabricへの移行をテストしています。トポロジーを検証すると、parcelラインに対して「内部と交差または接触してはならない」というエラーが約2000件発生します。これらのparcelは元々MapInfoで作成され、シェープファイルに変換しました。この大量のエラーを合理的に解決する方法について、何かおすすめはありますか？私たちのcountyには90,000以上のparcelがあり、1300のparcelで2000件のエラーが出るとなると、90,000のparcelではどうなるか非常に心配しています。<\/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).
