This short text continues articles about preparing the questions (fields) and answers (values) for use in Field Maps Designer. Here, I would like to briefly describe how to prepare categorized styling in ArcGIS Pro, which will be later used in Field Maps Designer.
We can start from the raw layer without any styling. Because I’ve chosen the point layer, the items are displayed as “dots.”
Styling our layer begins when we right-click on the layer -> Symbology (1). Initially, in the Primary Symbology section, a Single Symbol is selected. To categorize, it should be changed to the Unique Values (2). Next, the application asks about the field on which the Unique Values are based. By default, it would be the very first field from the list. The dropdown on the right can be changed quickly. When the proper field is applied (3), you can see the domain’s content, which has been set for this particular field. The default symbol is assigned to each domain value listed in the row. Double-clicking on this symbol will open the Format Point Symbol box (4). The ArcGIS 2D objects come as default in the Gallery tab. Once one of them is selected, we can toggle between Gallery and Properties tab (5), where another feature can be specified.
Completing optional adjustments for all the symbols allows us to see how they change in the key in the Contents panel and the list of symbols. When everything is completed, our layer should look like the one below, assuming all values represent NULL (Pic. 3).
The symbology for this particular layer is completed. It is advisable to export these settings to the file (Pic. 4) and load them on the next occasion.
Worth looking at is the layer name, which is directly transferred to the file name under which the symbology is saved. The ArcGIS Pro saves the symbology in .lryx files. Unlike the situation where the file includes the single symbology settings, here, the subsequent usage of the file would require the following:
– analog layer in the other project,
– the same domain content in the other project,
otherwise, the loaded file won’t work.
The primary advantage of styling our items in ArcGIS Pro is the much larger spectrum of icons we can provide and, therefore, display on our ArcGIS Online map.
Finally, when you are happy with the file, please share it with your ArcGIS Online account and load it to the map.
After sharing, I see that your layer and all the symbology work well in ArcGIS Online. All the symbols should be transferred without problems. Remember that if, at some point, you decide to play with the symbology on ArcGIS Online, you may lose the original icons produced in ArcGIS Pro. The reason is simple—ArcGIS Online doesn’t have a big symbol library.
