Combine themes of two layers

LondonPoliceGISAnalyst — Wed, 28 Dec 2022 15:58:00 GMT

I have two layers that point to the same feature source.

Both layers have around 25 classifications coming from the same field (store_type)

I want to combine the two layer definitions so I end up with a single layer that has all 50 symbols.

Is there an way to automatically combine them?

Copy and paste the lyrx files?

thanks

bring them into a map and

Merge (Data Management)—ArcGIS Pro | Documentation

then save the result to a new lyrx

The data is technically already 'merged'. Its a single feature source.

Two separate Layers that point to that one single feature source (stores).

Each are themed 24 icons for one, 26 icons for the other. (field: store_type)

I need a single layer with 50 icons without the hassle of recreating all the icons based on store_type.

Basically I need a layer merge (lyrx), not a data merge.

For those who are interested, there is a great tool for just this issue:

"Apply Symbology from Layer"

This allows you to take all the symbology (symbols, line types, etc) and apply it to an existing layer.

I solved this by taking my layer with 26 symbols (Input Layer) and merged with the 24 symbols (Symbology Layer).
The result is that I now have all 50 symbols in my Layer all themed to the column I chose.

Glad you found a method that worked, another option is to use the "Match Layer Symbology to a Style" https://pro.arcgis.com/en/pro-app/latest/tool-reference/data-management/match-layer-symbology-to-a-style.htm
