What makes Point features have invalid geometry

ScottLouque

I am trying to learn how to build a geometric network and want to include catchbasins and culverts in this network. However, when I go to build the network I get builder errors and all of these errors are bc my point features have invalid geometries. I am trying to understand what makes these point features invalid before I go and replace 5000 point features manually.

There could be an other reason that your line feature is added as a Simple Edge and is connected on both ends, in this case if your point feature lies on the edge, it will not snap and logical GN will give error of Invalid Geometry

Make your line features as Complex Edge then you wont get this error.

interesting... and right-clicking on the layer and going to properties, reveals nothing about the data? and it doesnt have the red ! mark beside it either? well, nothing like a fresh start then

ScottLouque

I don't know. This dataset was created years ago before I was in GIS. I believe it was contracted out

DanPatterson_Retired

how were they created?

ScottLouque

I think the problem may lie in how the points were created because I was going to try and export out to a lat/long coordinate system and it doesn't let me. The options to use the layers source data or use the data frame is greyed out.

You could also try Recover File Geodatabase ( Recover File Geodatabase—Help | ArcGIS for Desktop ). That will only bring over simple feature classes, but if your points are good in the recovered database, you can create an empty feature class with the same schema in the same feature dataset as the geometric network and then load objects into it (Creating a new network junction feature class in the Catalog tree—Help | ArcGIS for Desktop and Loading new features into your geometric network—Help | ArcGIS for Desktop [this one says use the Network Incremental Loader, but if you're loading a lot of points, the Load Objects command might be faster {Adding the Load Objects command to ArcMap—ArcGIS Help | ArcGIS for Desktop }])

Run the AddXY tool on the data and then look at the values in the newly created fields, viz., Point_X and Point_Y, do they look out of place, like Dan suggested i.e. 0,0

Well it is pretty hard to screw up a point and the repair geometry will do little to fix it Repair Geometry—Help | ArcGIS for Desktop

considering that the only thing that could go surficially wrong is that a null point is created which, from other threads, just returns a point object with 0,0 as coordinates. If it is returning a null object (like a python None or equivalent), then this could be readily detected. So where the points were created is equally important, particularly if the original data were in some other form brought into a file geodatabase, which just persists errors and doesn't correct them (see Checking and repairing geometries—Help | ArcGIS for Desktop )

Can you upload a sample of points that are causing issues? It is helpful to work with the points directly, or at least some of them.

ScottLouque

I haven't tried exporting out to a new feature class but I did copy all the features to a new Point feature class and that didn't work.

How about exporting all the points in your problematic feature class into a new point feature class and see if that fixes your geometry problems? This could fix all the points at once. Just a suggestion as I don't know if it will fix the issue until you test it.

ScottLouque

I've tried running the Repair Geometry tool on it and it doesn't fix the error. The only way I've found to fix the error so far is to go and manually place snap a new point onto the existing point and then delete the point that was giving me the error but I have over 5000 points that are giving me this error so was wondering if I could find out what cause the problem in the first place and then maybe could find a way to correct all 5000 of them through a geoprocessing tool rather than have to do it manually

Hi Scot

Have you tried running the Repair Geometry tool? It should fix your error

but not really tell the cause.

I think I may have just figured out a possible reason why these features are giving me an invalid geometry error.

I don't know if all these features were created in ArcMap. Some of them could have been created in another program and imported into ArcMap. Would this cause the invalid geometry error?

ScottLouque

No they are all point features. That is one of the things I thought it may be too but it's not. I even created a new feature class which I made a point feature type and copied all the points into it but it still gives me 'invalid geometry' errors

mvolz47

Do you by any chance have multi-points which are different than points?

ScottLouque

When I went to build the network I told it to snap all points within a specified feet of each other. So most of the points are snapped to my waterlines feature in the network

BenjaminMittler

Are the points snapped to the network?
