Help needed: Attempted to group habitats within aggregate class.

SimpleMapper — Fri, 13 Jan 2023 13:01:00 GMT

Hi there,

I'm using Arc GIS pro and I have been attempting to use the calculate field to organise these 'Broad Habitats' into their 'Aggregate Class' - so simplifying them in a way.

I created a new field within the attribute table and attempted to calculate the field. I thought I should add the 'Broad Habitat values', and then equal it to the 'aggregate class'. This screenshot below shows how I attempted this with the Semi-Natural Grassland 'Aggregate class'.

I added the 'broad Habitat' values together, but I got an error sign when attempting to apply it. any thoughts where I went wrong and how I can solve this issue? Am I on the right track?

Any help would be appreciated 🙂

screen grab just the dialogs to make them easier to read.

and if you are trying to do a field calculation, with a python expression, you need to enclose the field names in exclamation marks

!fld0! == !fld1

will return the fields where they are equal

Thank you for getting back to me so quickly.

And yes sorry for the blurry screenshots.

Hope this is better to read.

Do you recommend using Arcade instead of Python?
