This technical presentation offers a detailed walkthrough of Teradata's Geospatial features using basic geometry shapes. With points, lines and polygons, we demonstrate the power of our geospatial analytical functions using easy to understand SQL examples.

This presentation is an introduction to Teradata's geospatial features. Starting with a brief background to location data and the benefits that geo-location data provides over traditional addresses, we then discuss the powerful functionality now available with Teradata's new spatial data type and methods. The presentation demonstrates some examples of these features using SQL queries, some customer success stories, Teradata's geospatial EDW strengths and finally a view into Teradata's geospatial roadmap.

The availability of Teradata's geospatial extension package in 2007 brought these location capabilities to Teradata 12, 6.2 and 6.1. This package is still available as a free download from Teradata and when installed, adds geospatial functionality as a User Defined Type (UDT) along with a library of User Defined Functions (UDFs). (See my article on downloading and installing this package). One of the major highlights of Teradata 13 is the inclusion of thes

In my previous article we explored Teradata's spatial features using geometric shapes on a 10x10 grid. I hope this was a useful introduction into the new ST_Geometry data type and its powerful set of functions. And now that we've covered the basics, let's take a step into the world of geospatial. By geospatial, we're now talking about locations based on geographic reference points on Earth; for example longitude and latitude.

Now that you’ve installed Teradata’s geospatial features with Teradata Express let’s roll up our sleeves and see what we can do with this. (If you haven’t setup your TD Express with Geospatial yet, see my article. I think the best way to begin exploring these features is to start is with some basic geometric shapes.

We’re in the midst of an explosion in the world of location data. GPS tools have greatly expanded our ability to capture location data and mapping tools have broadly expanded its use. We have Web navigation sites like Google Earth and Yahoo Maps. Our cars have navigation devices to keep us from getting lost. Companies use GPS devices to track their shipments and mobile assets. Our digital cameras add location tags to photos. And we even have dog collars that can track Fido’s adventures around the neighborhood!
