I'm looking for a way to update the 'layer credits' into a dynamic text box. I've found ways of using the map credits or data frame credits here but can't seem a way to get the information derived from a layer.

I just seem to produce an empty string every time. Has anyone done this or found a work around? Seems like an extremely useful way to update map credits with little to no resources.

Derived Layer properties

  • There is no way to do this dynamically, as the built-in dynamic texts are all based on the document or data frame. However, this is definitely possible if you're willing to run a script to populate a text field every time you make a map. Or, even populate the map credits from all of the layer credits. If this is what you're after, I can provide some arcpy code to do so.

As mentioned in my comment above, there isn't a way to do this using dynamic text. However, you could write a script to do this and attach it to a python addin button or to run when you save the MXD or something. You'll need to create a text element to hold the credits and name it something like "CREDITS" as so:

enter image description here

The basic code would look something like this:

mxd = arcpy.mapping.MapDocument("current")
credit_text = ""
for layer in arcpy.mapping.ListLayers(mxd):
    credit_text += (layer.credits + "\n") # separate each line with a carriage return
for el in arcpy.mapping.ListLayoutElements(mxd, "TEXT_ELEMENT"):
    if el.name == "CREDITS":
        el.text = credit_text

    +1 That's how I'd do it - would have answered with much the same code.
