Applying and Extending Oracle Spatial

By: Siva Ravada, Simon Greener

Overview of this book

Spatial applications should be developed in the same way that users develop other database applications: by starting with an integrated data model in which the SDO_GEOMETRY objects are just another attribute describing entities and by using as many of the database features as possible for managing the data. If a task can be done using a database feature like replication, then it should be done using the standard replication technology instead of inventing a new procedure for replicating spatial data. Sometimes solving a business problem using a PL/SQL function can be more powerful, accessible, and easier to use than trying to use external software. Because Oracle Spatial's offerings are standards compliant, this book shows you how Oracle Spatial technology can be used to build cross-vendor database solutions. Applying and Extending Oracle Spatial shows you the clever things that can be done not just with Oracle Spatial on its own, but in combination with other database technologies. This is a great resource book that will convince you to purchase other Oracle technology books on non-spatial specialist technologies because you will finally see that "spatial is not special: it is a small, fun, and clever part of a much larger whole".

Sourcing available Java spatial technologies

There are a number of open source spatial technologies and projects that are a potential source of implemented algorithms, which could be deployed within the Oracle database's JVM, to complement or extend the existing Oracle Spatial software.

The following are some of the main ones that are available:


deegree is an open source software for spatial data infrastructures and the geospatial web.

JTS Topology Suite

The JTS Topology Suite is an API for modeling and manipulating two-dimensional linear geometry. It provides numerous geometric predicates and functions. JTS conforms to the Open GIS Consortium Simple Features Access– Part 2: SQL Option, Version 1.1 and 1.2 (OGC SFA)

GeoServe r

GeoServer is an open source software server written in Java that allows users to share and edit geospatial data.


Java Spatial is a spatial extension for relational database systems that implements the OpenGIS Simple Features for SQL and...
