Topoengine Error

BUSRAARIDURU — Fri, 08 Mar 2019 02:02:03 GMT

By using closest facility, I found closest path between 78 points. Now, I am trying to split this route at intersection points by using feature to line management tool. However, I am getting a Topoengine error. What I tried to solve this problem is that :

1. I used repair geometry.

2. I used check geometry.

3. I unchecked background processing from geoprocessing option.

4. I copied the data to new file geodatabase.

But, I could not fix this problem. If you have any suggestion to me, I will be appreciated for that.

Thanks !

Have you tried changing (not specifying) the XY tolerance?

Are you able to do some other geometry operations on the output routes. That is, try exporting the routes to a line feature class or buffer them.

I tried not specifying the XY tolerance, but again I had an error.

How can I export the routes as line feature class ? When I click on export the data, I could not see this option.

I used buffer tool, but I am still waiting to have a result.

Thank you so much !

Something to try: Run the Integrate tool (on a copy of the FC of course) to see if that will cleanup your futzy geometry.

I tried, I have an error " Invalid topology (out of memory). Failed to execute (Integrate)"

It looks like the original data has some corruption. Are you running the topology, intergrate, etc., on the original or the resulting route layer? You may want to contact Esri tech support and have them get the data in house and take a look at it.

I am running resulting route layer. Maybe, I did something wrong at the beginning, that's why I have an error. This is what I did :

I create network analysis from North America Major Highway. After that, I used closest facility to find shorthest path between 78 points. However, I found just 90 routes (From analysis setting, I set up as 78). I have no idea why I had just 90 routes.

Then I decided to apply feature to line tool to North America Major Highway, then I created network analysis, after that, I used closest facility and I found 78x78 routes. Then, I exported this shorthest path and I tried to use feature to line tool to this shorthest path, but I had a topoengine error.

Do you think that is this creating problem ?

What is the source of the original data for "North America Major Highway"?

This is the data I used :

Thank you so much !!

I believe this data is for "display". It is not really suitable for routing.

If you have an AGOL account and credits, you can use the online closest facility service and get routes with current street network. You can access this from the Ready To Use services in ArcCatalog.

Why do you think that it is not suitable for routing ? After exporting this data as shapefile, I created Network Analysis.

Actually, I have 234 CSD coordinates but since this program gave me a error, I decided to split my data into three excel file as 78 CSD coordinates. Do you think that can I find shorthest path between 234 CSD coordinates by using this online closest facility service ?

I saw Ready to Use Service, I signed up with my community esri account, but I could not see like what you are seeing in the Picture above. Is this online ArcGis ?

I need to purchase, right ? I saw monthly pricing.

Do you think that is this better to use rather than using route network file ?

Before that, I was studying on Road network files . Do you think that is this file suitable ?

Sorry for asking too many questions. I am appreciated for your help. !!

Thank you so much!!

>Why do you think that it is not suitable for routing?

This data does not contain any information on transportation related attribute such as drive times, speed limits, one-way information, turn restrictions, how the ramps connect (z-levels), etc. If you create topology and flatten out these intersections then you will get wrong paths. There are many other things needed to make a meaningful road network.

You also mention:

>I was studying on Road network files

If you see the information on that web page, it says: "these files are not suitable for engineering applications, emergency dispatching services, surveying or legal applications"

So it depends on what is your use case for the routes you are creating.

As far as ArcGIS online, you could create a new trail account and try out these ready to use services. It comes with some limited amount of credits. More information here:

Thank you so much for your answer !. I am appreciated for that. I did what you suggest to me.

These are the steps that I followed :

1. I signed up ArcGis Trial.

2. Then, I used closest facility from ready to use services.

3. I found shorthest path between 78 CSD coordinates.

4. I exported this shorthest path.

5. I applied feature to line management tool to split line at their intersection points.

6. I got an same error saying that invalid topology (topoengine error).

I really do not understand why I have to use Online ArcGis. I can find shorthest path between points by using North America Major Highway. But, my porblem is coming when I appyly feature to line tool to the shorthest path.

Thank you so much!!

I am appreciated.
