New elevation color-relief hill shade layers.

Over the past few weeks, fellow GINA GIS analyst Mitch Slife and myself have been busy in the GIS lab cooking up something special.  We have been working on creating a new set of shaded color-relief images. Inspired by an old post by Tim Sutton on linfiniti.com, we focused on a fully command line workflow for generating geospatial masterpieces without  restrictive obstacles like graphical user interfaces.  This fully command line approach will allow us to scale this new hill shading to a variety of other elevation datasets in our archives.

 We will be following this post up with links to the new datasets in our Web Mapping Services (WMS) and catalog system so those interested can start using these hill shades in their day-to-day GIS visualization activities.
