I am trying to combine about a dozen gdb polyline (river and stream) feature datasets into a single layer. The multiple feature datasets come from an outside source and they would like to see these combined to analyze one of the fields in the attribute tables. The shape files include grid data, with Grid 1 data being different for each one, and Grids 2 and 3 being 0. A number of other fields include domains, but only a few of them differ slightly from dataset to dataset.
I am using ArcGIS 10.6. I've used the following methods each resulting in the problems mentioned below:
Merge Tool - There should have been a total of close to 100,000 records when the datasets were merged, but only about 40,000 were in the final merged dataset. One of the feature datasets had about 50,000 records and only 1 of them ended up in the merged dataset.
As a test, I tried to combine only two of the datasets using Append:
Append Tool – I didn't want to alter the first (target) dataset, so I made a copy of it. This was one with less than 100 records. I tried appending the large (50,000) dataset to it (the grid value differed in the shape field, but the domain entries were the same for the other fields). It ended up appending the data to the original (target) dataset, not just the copy, which was not desired.
Append Tool – Instead of copying an existing dataset, I created a new feature class, importing the fields from the target dataset I had used in the attempt above. When I tried to append a dataset to it, nothing was imported into the new feature class. When I looked at the field properties, no grid information was showing for the shape field, and none of the fields included a domain.
Any help here would be greatly appreciated!
Thank you,
Judy
