Update to PL/SQL Packages

Thursday February 15 2007 at 03:09

Today I uploaded some changes to my Oracle Spatial and Locator PL/SQL packages and types source code which is available as a free download from this site.

The changes include:

  • A new TO_KML() function in the GEOM package (I thought of calling it GEOMETRY2KML or TO_KMLGEOMETRY but decided against it).

This allows for the conversion of any geodetic sdo_geometry object to be converted into KML via GML. It does so not via XSLT but rather by hacking the GML produced by the SDO_UTIL.TO_GMLGEOMETRY() function. It is not meant to be a complete or totally flexible method for converting sdo_geometry to KML but to give an indication of what is possible. This function could be used in a trigger with the UTL_SMTP package to email a KML description of a geometry to someone with Google Earth as a quick visualisation/check of a geometry. Or it could be used inside an Application Express form or report for downloading or visualisating a batch of sdo_geometries.

  • Some additional test data has been constructed;
  • Some minor improvements in TOOLS.GeometryCheck;
  • Changes to some of the test functions.

Enjoy!
