What does GP and DE mean as seen on parameter data types.

Do they have an affect on what data is shown in the browse dialog box?

I don't believe the prefix is documented anywhere. If I remember correctly:

  • DE = data element
  • GP = geoprocessing

They don't really mean anything to you, the tool developer. There is only ever 1 of each. There isn't a DEString and a GPString for you to choose from.

There is probably some history as to why there is DE and GP, and a best guess would be something to do with arcgisscripting and arcobjects. But yeah, I dont know those details.

  • Okay that kinda makes sense. I am guessing DE is an actual resource to be used and GP is used for configuration. There is a DEType and GPType but I get what you mean.
