Regras de Conectividade da Rede Geométrica ao usar o Local Government Information Model

Question

<\/HEAD>Estou tentando encontrar alguma clarificação sobre uma pergunta que surgiu ao fazer a aula Trabalhando com Redes Geométricas para Utilities. Ao usar uma rede geométrica para acelerar tarefas comuns de edição, os exercícios nos fizeram definir "Subtypes" (não Domínios) nas classes de feição participantes que poderiam então ser usadas para configurar regras de conectividade. Por exemplo, ao encaixar um ramal em uma linha principal, um acessório do Subtype "Tee" é criado automaticamente. Outras regras podem ser: um hidrante só pode conectar a um ramal de hidrante, e apenas 1 metro pode conectar a cada ramal de serviço.<\/SPAN> <\/P><\/P>No entanto, foi enfatizado que os campos de subtype devem ser campos inteiros (com domínios codificados). <\/SPAN><\/P><\/P>Acabei de terminar a migração dos dados do nosso distrito para o Local Government Information Model. Contudo, o LGIM não usa campos inteiros para os atributos para os quais eu criaria subtypes (FITTINGTYPE, LINETYPE, WATERTYPE etc.); ele usa campos string que não podem ter subtypes criados e, portanto, não podem ter regras de conectividade definidas na rede geométrica.<\/SPAN> <\/P><\/P>Estou perdendo algo? A Solução Water Utility Network Editing da ESRI contorna isso?<\/SPAN><\/P><\/BODY><\/HTML>

Hi Ryan,

I think we took the same class in February; small world! I would be very interested in what the City of Sacramento is doing, especially since it sounds like you are at the same stage. Plus, Carmichael Water District's data and your data will likely feed the same regional hydraulic model in the future. I "followed" your profile on GeoNet, so you should be able to send me a personal message now.

Our contractor who helped us just finish our LGIM migration is an ESRI gold partner; the current answer I'm getting from him is that the custom tools in the Water Utility Editing and Analysis Solution give you the same type of rules enforcement as using subtypes in the Geometric Network. We are just about to install and test our custom configuration file that informs these rules - I will report back on how it goes.

If, for some reason, the integer subtypes are necessary we will go back and modify the migration. But thinking ahead, we've been told that the LGIM is moving toward the new Utility Network schema, and that the custom tools in 10.4 Desktop will be built in to ArcGIS Pro. Staying at the July 2016 version of the LGIM/Geometric Network and then using ESRI's migration solution to the Utility Network and Pro (after it has been vetted) is our plan.

We experienced the exact same thing.  We only realized this after we had finished designing our new model off the LGIM and had to go back and convert specific domains into subtype fields to allow the more granular rules we wanted to build and enforce.  I can send you an XML file of our current schema as a reference if that helps.
