A very popular and enduring request of the ArcGIS Online user community has been to have the ability to symbolize features based on data that’s stored as a related record. Well, Esri has listened- and released in a June 2018 update to ArcGIS Online the ability to use related records data like never before. We now have the ability to symbolize and manipulate our data in ways that we previously limited.
To utilize the ArcGIS Analysis feature, follow these steps:
Log into ArcGIS Online and either create or open a previously created Web Map
Select from the web map the layer in which a related record exists, and click on the Analysis symbol (as seen below)
3. Once the Analysis window opens, we now have the option to manipulate our data in several different ways based on the desired data analysis method.
4. For related records specifically, we’ll want to select “Summarize Data” and from the drop-down menu, select “Join Features”
5. Next, we’ll want to specify the input parameters. The “Target Layer” will be the layer that the related records are attached to. Likewise, the “Layer to Join to the Target Layer” will be the related record that will be symbolized.
6. Then we’ll finish filling out our parameters based on the desired related records end result symbolization. We’ll want to match the fields from our target layer to the join layer (these fields could the same fields on which the relationship class for the related record was built). Choose a one-to-one or a one-to-many join operation, name the result layer and where it will save the output layer to, the check the box “Create results as hosted feature layer view”
7. Finally, click the “Run Analysis” button at the bottom of the window, and a feature layer view will be generated that you then will be able to symbolize based on the related records attributes.
