Spatial Companion For Oracle – Java COMPLETE (EXPORTER+JTS) Edition

$17.50 (inc. GST Australia)

The Spatial Companion For Oracle (SC4O) 12.1 Complete Edition, is a set of Java Stored Procedures based on the well known Java Topology Suite with extensions from the JASPA project (mainly 3D WKT/WKB functions). Some functions (ST_Union etc) provide Locator users of Oracle before 12c access to otherwise Spatial functionality. Some of these functions provide an implementation that is more in line with the results provided on other database platforms (such as PostgreSQL/PostGIS). SC4O also provides for some advanced functionality such as ST_PolygonBuilder. This version includes all EXPORTER functions.

Description

The Spatial Companion For Oracle (SC4O) 12.1 Complete Edition, is a set of Java Stored Procedures which expose some Java Topology Suite functions. (And a few functions from the JASPA project (mainly 3D WKT/WKB functions).

This package includes all the Exporter functions.

Exporter (Java Stored Procedures):

Documentation of the Exporter functions can be seen at this link EXPORTER Function Documentation
