In GIS, spatial data is regularly stored/transmitted as text. With this comes metadata, including the projection used.
Example Issue: When extracting data from ESRI's ArcGIS REST Directories, the projection can be extracted from the information, but must be manually defined in the Make Points Tool. If you are trying to compile data from several different sources, all using different projections, you cannot automate the process.
Suggested Solution: Add WKT to macro interface configuration options so that an Action Interface Tool can update the Create Points Tool.
