Traditional wall maps become powerful visual references when scanned, georeferenced, and made into Google Earth layers. The maps you currently create in Petra, GeoGraphix, ArcGIS, AutoCAD, etc. can be easily distributed, archived, and organized in this format so your work does "double duty" in both the paper and digital worlds.

The key to viewing large, detailed images in Google Earth is creating tiles of progressively greater detail that load as the user zooms in for a closer look. As you move around, tiles are pulled from the server. Once an area's tiles are loaded, Google Earth uses its cache to serve them up quickly upon revisit.

Wall map overlays are most effective when deployed with Google Earth's transparency functionality. While you can read more about the transparency slider in our Viewing Tips section, we present a typical GIS-type map of Kansas oil and gas fields with transparency already adjusted, allowing one a view of the underlying terrain, agricultural activity, etc.

**If nothing happens when you launch these layers, please make sure you have the most current version of Google Earth installed.

NOTICE: Google Earth makes intensive use of your graphics card. Older hardware may not be able to elegantly handle the quantity of visual information presented here. See Google's own recommendations here for more information.
