Not able to merge the layers of point data. Only one layer shows up after merging.

bee

I'm new to this. I am trying to merge two layers of points to one. I went to Analysis > Tools > General > Merge. I entered the two datasets and hit "run." It generated a "merged" later in the content. However, upon checking, I can only see one dataset. I checked by selecting Appearance > Symbology > Unique Value and see that only the values for one set were included in the layer. I'm clueless as to what's wrong because I've done merge in the other project and didn't have the same issue.

Turns out I have to shorten the layer names. It works now. Thanks for looking into this for me, everyone! 😊

you are asking for problems with those paths. They contain spaces, and punctuation (excluding _ , which is ok).

as suggested earlier...

don't judge the merge on the symbology. open the table and see if the number of records in the output table is equal the sum of the two input featureclasses.

If it does, try resymbolizing, since I suspect that the field you used for symbology wasn't present in both tables and you didn't look at the field mapping options

DylanT_EsriCanada

Another thing to be careful of is having features selected. Often tools will only operate on the selected features.

bee

Yea, I checked the Attribute Table and it shows the exact number of one of the two layers. I then switched the order of the layers and merged again; and again, I get the exact number of the other layer.

bee

No... I didn't select any features..

bee

The field for the symbology does appear in both sets.

,Hi @bee ,

If you want to keep the attributes data from both layers, you will need to complete a table join Add Join (Data Management)—ArcGIS Pro | Documentation.

Merge (Data Management)—ArcGIS Pro | Documentation

to combine 2 files into one output file... with field mapping

DanPatterson

Are they both featureclasses in a gdb?

Why don't you take a screen grab of the dialog from arctoolbox showing the inputs and the output featureclass names.

That is true or you can use the Append tool to merge the two files into one Geodatabase Append (Data Management)—ArcGIS Pro | Documentation

Looks like the Merge tool keeps all the attributes by default according to the documentation.

@bee Can you post screenshots of your tool parameters?

Nicole_Ueberschär

I think if the fields are the same I would also try to use the append tool. Still, the merge should bring the desired result.

Which software version are you using?

Can you try to add the two layers in the opposite order? Does is then bring only the other layer's data?

Some screenshots from the tool's settings would be helpful!

bee

The fields are pretty much the same.

I did try to add the two layers in the opposite order and it always brings only the other layer's data. Below is the screenshot of the merge tool I used.

I had to geocode one set with full addresses and the other set with coordinates and that's why I had two layers.

Here it is. Thanks for your help.

Here is more info. Thanks, everyone, for helping!

What is the second dataset?

What is the full path to the output data set?

bee

C:\Users\byuen\OneDrive - East Bay Company\Documents\ArcGIS\Projects\MyProject5-2000_Trail_Permits - Copy\MyProject5-2000_Trail_Permits.gdb\TrailPermitCAFullAdrsGeo_Geo14

you are asking for problems with those paths. They contain spaces, and punctuation (excluding _ , which is ok).

They also don't all look like featureclasses. If you have event layers or other data types, make them featureclasses. That is what merge works with.

Thanks! Here are my rookie questions:

1. Do I have to move these files to get a "cleaner" path?

2.Do you mean that I should convert the layers to feature class, and then merge the two? If so, how do I go about it? Thanks for your help!

DanPatterson

Create a file geodatabase in a simple folder path (eg c:\data )

Create a file geodatabase—ArcGIS Pro | Documentation

Use Copy Features (Data Management)—ArcGIS Pro | Documentation to copy those to the gdb.

You still haven't answered the question as to whether the data are featureclasses to begin with?

right-click on the layer and check out the source and properties

You could also try performing the GP tool on a local location instead of on One Drive.

Anonymous User

Hi @bee ,

You can use the GP conversion tool to convert your files to the Feature classes. The second one looks like a table - so it would be useful to convert this, and having them the same type should help.

Create points from a table—ArcGIS Pro | Documentation

also, what are the Geolocation types of the files,

One looks like address geolocation and the other one? Is that addresses or is it co-coordinates ?

bee

I've confirmed from properties that both layers are feature classes.

bee

Hi Keiren - I've confirmed that the layers are feature classes. You are correct that one set is address geolocation and the other is co-coordinates. Is geolocation type an issue?

Hello,

I am having a similar issue: trying to merge different feature classes from the same feature data sets, except only information from the first file listed is retained in the merged feature class. There are entries for the other merged items, just all information in the merged feature class is <null>. I tried shortening the feature class names, but that did not resolve the issue. Any help would be appreciated.
