Creating local-tangent-plane Cartesian CS
697015Apr 19 2010 — edited Apr 22 2010Good day, colleagues!
I need to write a procedure to preprocess my spatial data from Google Earth before loading. To do this I must convert data to local-tangent-plane Cartesian CS. As I can see from Spatial Developer's Guide, I must create a new coordinate system. As I can see, coordinate transformation method for local-tangent-plane is ESPG 9840.
The issue is there is no 9840 method in sdo_coord_op_methods. At the same time I see, that Oracle Spatial can built-in possibility to convert to local-tangent-plane CS. Oracle Spatial Developer's Guide: "When these functions are used on data with geodetic coordinates, they internally perform the operations in an +implicitly generated local-tangent-plane Cartesian coordinate system+ and then transform the results to the geodetic coordinate system."
So, how how can I convert my data to local-tangent-plane CS? Should I code conversion method by myself or I can do it with the help of Oracle?
