I need to extract polygon coordinates from various sources like shape, tab, kml etc. I am using generic reader to read source dataset. I want to know which is there any transformer which will do this job. I know CoordinateConcatenator is not suitable for aggrgates. So what is alternative to this. Anything I need to take care of in regards to how polygons are stored in Oracle Spatial. I need to handle all types og polygons simpe, donuts, aggregates/collections.
What is the best way to achieve this?
