The guide contains a brief overview of how the WorldWind clients make requests, followed by instructions for setting up the Apache web server, MapServer and the Apache caching.

Overview

WorldWind clients consume imagery data in PNG, JPEG and DDS formats obtained from a MapServer instance via OGC WMS requests. The NASA WorldWind imagery server provides Blue Marble and Landsat7 imagery to WorldWind clients as the core imagery services
