This Visualization is simply the idea of generating a digital image or video to show how features are related to each other. This could be draping a fire perimeter over a surface, creating a ‘fly around’ of a maintenance structure or building a ‘fly through’ to show an area from a pilot’s point of view. In each of these, there is usually less emphasis placed on the data and spatial attributes. One shortcoming of visualization is that it is difficult to obtain specific information such as, “how many acres is that polygon” or “how long is that section of road”. However, the idea of simply showing how things ‘look’ on the ground can be beneficial. For those working with GIS, ArcMap is the software that used to create maps and ArcCatalog is the software used to navigate through the park’s data. Also included in our suite of software are two packages that can be used to create 3D representations. These are ArcScene and ArcGlobe. Either program can be accessed by looking under the ‘Start’ button, ‘All Programs’, and then under the ‘ArcGIS’ menu. If you are
not familiar with using GIS or if you would like to look at some
of the working products used to create visual tools, you can visit
the Wind Cave Main Server where some sample files have been stored.

these graphics are working copies and therefore have some 'rough
edges', but I think they will offer some insight into the possibilities
of working with 3D visualizations. Remember if you are interested
in learning more, everyone has access to the Virtual Campus where
online classes are free to Park Employees. Record
