New PL/SQL Packages - Rotate oriented point
· May 31, 04:04 pm by Simon Greener
I was asked if I would enhance my pl/sql Rotate function so that it handles oriented points. (Note: Oracle’s sdo_util.getVertices() does not support the oriented point.)
After a bit of coding and modification of GeoRaptor so that I can visualise the result, I have finally finished the code and uploading it to my website. The GeoRaptor changes should be available in the next release.
Here is an example of using the GEOM.ROTATE function to rotate an oriented point and visualising the result in GeoRaptor.
