We are performing a proof of concept with Denodo. For our organisation spatial data is of uthermost importance. In the documentation of the Xtrafunc functionality I can see there are some spatial functions (https://community.denodo.com/docs/html/document/denodoconnects/6.0/Denodo%20XtraFuncs%20-%20User%20Manual)
I cannot find these spatial functions in the express version of Denodo. Is this not available there or am I missing something in my installation (using on premise software)?
