I need well know text (WKT) information to download data from another source.
I have a shapefile that represents zip code polygons; what tool or process can be used to create WKT information for each of the polygons? I am using ArcGIS Pro 3.1.0 and the largest dataset has ~1500 zip codes.
You can use the Calculate Field tool to calculate a text field with this Python expression:
Ah, thank you for sharing this! If I was using point data this would be the way to go. I will keep this in mind if the project decides to move forward that way.
I remember doing something similar: Field Calculator to get JSON text
I made the mistake of making my text field too small. The JSON text wouldn't fit.
So if you run into any issues, that might be something to check.
The shapefile limit on character width (254) means you can only reliably store ~10 vertices in a dBase file. Rectangles and hexagons are possible; countries, states, counties, and even circles are not. Zipcodes would need to be dumped to CSV or processed in memory, because they could not possibly be stored in a shapefile.
Hi, my apologies, I am just getting back to this task. Do you have a link with more information on how to do that (dump to a CSV)? I have not done that before.
