Toevoegen van From- en To-ID's aan een Line Feature Class vanuit een Point Feature Class

Question

<\/HEAD>Ik heb lijnen die afwateringsstructuren vertegenwoordigen, gedigitaliseerd van upstream naar downstream en punten aan elk uiteinde van de structuren. Het punt is vastgezet aan het uiteinde van elke polyline. Is er een manier om de From- en To-punt-ID's (ik heb unieke ID's toegewezen aan elk punt) van de point feature class toe te voegen aan de line feature class waaraan het is vastgezet? Ik gebruik ArcGIS Desktop 10.3. <\/P> <\/P> Dank u!<\/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
