Creating line segments between 2 or more points

DavidKossowsky

Hello,

I am trying to create line segments between different cities in the world. I've previously used Spider Tools: http://arcscripts.esri.com/details.asp?dbid=14908 and it worked quite well when I was mapping from one main point to many others. e.g. A -> B, A -> C, A -> D, A -> E....

My issue now is that I have connection cities in between, so I need to map
A --> B
A--> B --> C
A --> C --> D
A --> B --> E --> F ...

Does anybody know of a way I can get these lines to automatically be created? It seems like it would be relatively simple - just connecting the dots based on location, but I can't find anything that would do this for me.

Thanks!

Hi there,
I'm having a similar problem (http://forums.arcgis.com/threads/11686-Spider-lines-with-a-twist-how-to-get-from-point-A-to-point-B-via-point-C?highlight=spider+lines). Did you manage to solve yours?

Hi skimmer,

No solution yet. I've been trying to tweak spider tools and my data to assist in the calculations, but as I too have many many points (about 4000), it is impossible to divide up the data in such a way that I can calculate all the routes and still manage all the layers.

I'll keep you updated if any progress is made. Please do the same for me.

Thanks,
David

P.S. I have looked into Network Analyst quite a bit but from what I've seen it doesn't help with this issue. I'm not sure if anybody else is able to confirm this..

I posted on Skimmer's thread already but you should try Xtools Pro. (Search on Google) It has a point to line feature that allows you to have a sequential number and an ID property. So basically it will create a line between multiple points in order if they have the same ID. Your problem seems a little more tricky then Skimmers but you could try to create different ID and Order fields based on specific properties.

Mr_Kirkwood

is there a Spider tools that works with Arc 10?

I would check out the new "Points to Line" tool that's included at ArcGIS 10.

Data Management Tools > Features > Points to Line

http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//00170000003s000000.htm

Thanks! that worked...

Is there an equivalent to "points to line" in the silverlight API?

Hi, I'm a beginner in Arcgis and I have a similar problem as dakaye. I need to create segments between points but the problem is that some points are repeated in many segments. That's why I can't use "Points to Line" tool in Arcgis 10. I have data like:

segment id, starting point id, end point id

It looks really simple but though I spent a lot of time by searching I still don't know how to figure out. I would appriciate any help. Thanks

could you provide more detail? Maybe a snapshot of your data, or if its ok, post it here?

Here are some data. start_point and end_point are IDs of existing points in my map (no coordinates). You can see some points should be common for several segments. Thanks for your help.

OK, here's what I would do. Not sure if there's an easier way, but:

Create X, Y for the starting points and for the ending points. Then you can do XY to line. Where you'll enter the Start X Field, Start Y Field, End X and End Y. You'll also be able to chose what kind of line, enter what field is the ID and the spatial reference. But it'll work.

SlukaLesni

Thanks a lot for your answer. It really helped. I finally managed to do it by assigning coordinates of the points to the IDs in excell and then it was easy with XY to line.

NicoleHanson

Yea! Glad it worked!
