Parcel Fabric, Não deve intersectar ou tocar o interior

Question

<\/HEAD>Estamos testando com um grupo de aproximadamente 1300 parcelas para migrar para o Parcel Fabric. Quando validamos a topologia, recebemos aproximadamente 2000 erros de "não deve intersectar ou tocar o interior" para as linhas das parcelas. As parcelas foram originalmente criadas no MapInfo e convertidas de um shapefile. Alguém tem alguma recomendação sobre como resolver essa quantidade de erros de uma maneira razoável? Nosso condado tem mais de 90.000 parcelas e se 1300 parcelas resultam em 2000 erros, estou realmente <\/EM>preocupado com o que 90.000 parcelas irão retornar. <\/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).
