If you’ve ever wondered about our Express Server product — what it is, what it does, how it works — relief has finally arrived. Not that you couldn’t always just call or email us and bat the subject around with a sales representative (you still can), but for those shy persons among you and those of you who like to do research before committing yourselves to conversation, you can now read all about Express Server image serving software in the quiet of your own browser.

GeoPlace.com has published a new LizardTech white paper titled “How Express Server Software Improves Geospatial Image Delivery”. It provides an overview of what Express Server does, describes how it fits into geospatial workflows, and then dives into some of Express Server’s more amazing features and how they work. We can feel your curiosity brimming over even from where we’re sitting.

• Do we describe the different caching strategies that enable Express Server to put pixels in front of users fast, whether or not the imagery is being used to satisfy WMS requests, or being reprojected upon delivery? We sure do.
• Do we explain how Express Server knows how to overlap one tile over another in a mosaic when an image’s transparency values get changed in compression? You bet!
• Do we show how JPIP-enabled clients can request image data to be streamed across low-bandwidth and even intermittent connections? Of course.

All this and more.
