But you can always move that into a bunch of ifs' as you deem necessary.Īll you have to do is use the pre-logic script code area to write a function which accepts the widthText and returns the widthNumber.

Video created by University of California, Davis for the course Fundamentals of GIS. So we can either use a dictionary to sort of recreate the switch or simply load up on ifs'. Geometry objects define a spatial location and an associated geometric shape. The ideal case is to use a switch case (Java/C#), but those don't exist in python. including feature geometry Ways to load CSV file in python In ArcGIS Pro.
the Field Calculator geometry calculation will use calculate the area.

I'm making the assumption both fields are in the same feature class/shapefile and the widthNumber field is an int of some type. To learn more about Arcade expressions, see the ArcGIS Arcade guide A. I am trying to solve the travelling salesman problem in QGIS and ArcGIS Pro but. Starting in ArcGIS 10.0, the attribute table also exposes the raw Geometry object of each feature to Field Calculator.
