Dear Jan,
thank you very much. I will use coordinates from a generalized version of the national park border for future downloads. This will reduce the length of the string significantly and will still be accurate enough.
Best regards Michael

Dear Michael,
In case you have not received a reply yet - If you are submitting requests through the GBIF API there is a limit to the size of the string that can be submitted. It would seem that a 1000 coordinate pairs would break the limit. I would recommend downloading data for the general area you are interested in and filter using a GIS application. I have done something similar using a complex polygon in R and I can help you in this regard.
Sincerely,
Jan K. Legind Data manager, GBIF

Dear all,
I'm working on a procedure for data download for the "Lower Saxon Wadden Sea" national park using the API. It works for a smaller region defined by a polygon with 183 coordinate pairs (vertices). For a larger region (more than 1000 coordinate pairs), I receive status 400 and the following response text:
Instantiation of [simple type, class org.gbif.api.model.occurrence.predicate.WithinPredicate] value failed: null (through reference chain: org.gbif.api.model.occurrence.predicate.WithinPredicate["geometry"])
My question is where the limit for the number of coordinate pairs is.
Thanks for help.
