How to count the number of intersections in line features

[roycastanares]

Hi everyone,

 

 

Can someone help me with counting the number of intersections in the line features I have digitize.

 

When digitizing, I made it sure that I have nodes or vertex in intersection then I snap on those when digitizing the intersecting line. But now my problem is extracting just the intersection, not the vertices.

 

 

I know there should be an easy way but right now, what I have in mind is this:

 

1.Convert line to points,

 

2.Then check the x and y position of points,

 

3. Those points that position appears more than once are the intersection so I can just delete other points that in now repeated twice or thrice. Right now I only have 1000 points. My concern is when I have too many features.

 

Is there an easy way of analyzing this. Thanks.

 

 

I am using SuperGeo GIS desktop from taiwan that is alike to ArcGIS.

 

Thank you very much.

i solve this problem  using arcgis 

you can build network dataset

But can you please tell me the basic of the analysis you have made by building network dataset.

 

 

I'll try to apply it to the GIS platform I am using now, SuperGeo GIS Desktop 3.2

Thanks.

You mention about a specific software which has never been used by most of us here. Hopefully somebody who has tried SuperGeo GIS can give feedback to the case.

 

In case you don't find the answer, try ArcGIS for an easy answer.
