When you see satellite imagery of the earth in a TV newscast or in a Web mapping application, that imagery is likely to be from DigitalGlobe, an Oracle Spatial customer and partner. DigitalGlobe is a world imagery products and services company with massive amounts of data to manage, including spatial information, customer information, and transactional processing data. Almost every element of DigitalGlobe’s ground system interacts with Oracle in some way, whether it’s their customer ordering system, satellite image collection planning, or production/order fulfillment.
In its raw form, satellite imagery is some of the highest volume and most demanding data to manage. Just a few city blocks of raw imagery at high resolution can take up hundreds of megabytes. As DigitalGlobe’s imagery collection capacity and customer base have grown over the years, Oracle Database and Oracle Spatial have provided a reliable, scalable platform to accommodate the demands from DigitalGlobe’s global operations and customer base. DigitalGlobe also takes advantage of Oracle Spatial’s geodetic model, as opposed to a flat earth model, to calculate areas in any number of units.
New DigitalGlobe Web service tutorial on OTN
To ensure that Oracle users can access imagery content in simple, fast ways, DigitalGlobe has posted an in-depth tutorial on Oracle Technology Network. The tutorial explains how to use imagery content, served up as tiles, from DigitalGlobe’s imagery web service in an Oracle Fusion Middleware MapViewer based web mapping application. It first outlines how to use DigitalGlobe imagery as a basemap in a MapViewer application using the Oracle Maps Javascript API and its external tile layer interface. Then it goes into advanced usage of the various APIs, namely DigitalGlobe’s jImageConnect and ImageBuilder and MapViewer’s Oracle Maps, to query, select and display imagery collections by date, resolution, or sensor.
