Adicionando IDs de Origem e Destino a uma Classe de Feição de Linha a partir de uma Classe de Feição de Ponto

Question

<\/HEAD>Eu tenho linhas que representam estruturas de drenagem digitalizadas do montante para o jusante e pontos em cada extremidade das estruturas. O ponto está encaixado na extremidade de cada polilinha. Existe uma maneira de eu adicionar os IDs de ponto de origem e destino (eu atribuí IDs únicos a cada ponto) da classe de feição de ponto para a classe de feição de linha à qual ele está encaixado? Estou usando ArcGIS Desktop 10.3. <\/P> <\/P> Obrigado!<\/P><\/BODY><\/HTML>

it depends on which way you do the join, point to polylines  or polylines to point with a spatial join.  There are also several options to control how is is done, which geometries are replicated and what attributes are kept. Spatial Join—Help | ArcGIS for Desktop

sometimes you need to combine spatial joins with attribute joins to get the data in the format you want....barring that, it is code time, but invest in the tools that are available, since your situation is not unique I am sure of that.

PS  I didn't look at linear referencing tools and I can't remember offhand whether there may be something useful there.

That would work except I have one point connected to multiple pipes. So one point could represent both upstream and downstream depending on the pipe it's connected to.

Well you could at least add the attributes of the start and end points of the lines using

Add Geometry Attributes—Help | ArcGIS for Desktop

then a spatial join, might be good methods to co-locate the data
