A little bit, but what I don't have any experience in is how I would integrate that with the existing model. Were you thinking something like a dictionary of the polygon ID and the date, and then comparing each date for each point with the same polygon ID, and updating the date value if it's older?

Hello, I have a feature class of polygons and another of many points, and the points have a date field that I'm interested in joining to the polygons. However, I only want to join the oldest date from all of the point features that intersect each polygon. My thought process is that I'd do something like this: 1) Spatial join a unique identifier from the polygons to the points 2) Create a subset of the points feature class containing the oldest date points for each unique polygon ID 3) Join the dates of the new point feature class back to the polygons Does anyone have any suggestions how to accomplish step 2? Or if there's a completely different method, I'm open to that as well. I'm using 10.2. I've accomplished this somewhat manually previously by exporting the points to a spreadsheet, sorting them by date, and then doing a VLOOKUP for each polygon so that the first point match it finds is the oldest date for that polygon. But I'd really like to have this process as part of a larger model.

I gave it a try, and that gives the same result as running a Dissolve with Create multipart features unchecked. There are still adjacent lines that aren't being merged.

I'm trying to dissolve all adjacent line features in a single feature class, so I'd like to only have separate features if they are not intersecting any others in the same feature class. The way it's working right now is that line features are only being dissolved if they share an endpoint with exactly one other line feature, which isn't how I would expect Dissolve to work based on the description. I have the same problem whether Unsplit Lines is checked or not. The attributes are not important to me. Is there a way to do this with Dissolve, or is Merge a better option? Thanks!
