Our foresters create new polygon features of harvest blocks they plan to harvest in the future. Each one is attributed with a start date for the harvest. I need to group them by year and symbolize them without having go into the layer properties and adding any new dates. Being able to symbolize a range (ie. 1/1/2021 to 12/31/2021) would be the best solution but I know I can't use quantity renderers.
Anyone have a good workaround?
@ScottRobinson If all the dates are in a standard format, you could just split the year out into a new field
Using something like !DATE![-4:] in the Field Calculator.
Then just symbolize using Unique Value on the year.
There are probably a number of other ways to do this, but this one should work pretty easily.
I've done that and it works. I've also used year() and that works, too. Trouble is our foresters are continually adding new polygons with new dates. Those won't get picked up unless I go in and do the field calculator.
OK, so you need it calculated automatically when a new feature is added. Have you looked into using Attribute Assistant https://solutions.arcgis.com/shared/help/attribute-assistant/ (for ArcMap)?
In ArcGIS Pro, this would be done using Attribute Rules. https://pro.arcgis.com/en/pro-app/latest/help/data/geodatabases/overview/an-overview-of-attribute-ru...
