Geospatial features were available as external UDFs in TD 12?

Hi,

I heard someone saying that Geospatial functions introduced TD13 onwards were available as external UDFs in the earlier versions. I have been asked to compare the metrics of using these External UDFs and native Geospatial features. My problem is that I have been looking for any examples of such external UDFs but have been unsuccessful.

Does anyone here any idea about this? Does using native Geospatial features really improves my system performance compared to using UDFs for the purpose?

Any help regarding this is greatly appreciated. Thanks in advance!!!
