Interactive Journey Page
At this time, please open the Interactive Journey page from the Upper Sevier site. You should be able to alternately bring this page forward to read this text and bring the Interactive Journey page forward to look at the features being described. If your screen resolution is high enough you may be able to see both of these pages side by side.
Notice again that the graphic elements on the top of the page are similar to other main pages on the web site, except a different picture is used and this is identified as the Interactive Journey main page. Another small picture is placed on the bottom left side of the page.
The HTML text on the left side of the page invites the user to begin an Interactive Journey into the watershed by choosing one of eight sections of the digital terrain map seen on the right.
Above and to the left of the map is an Elevation Color Key. This map originated from U.S.G.S. Digital Elevation Model (DEM) files. Corresponding to commonly used topographic maps with 30 meter terrain accuracy, approximately 75 DEM files were used to make a map large enough to cover the entire watershed area. Programs we used for this project included World Construction Set made by 3D-Nature and Natural Scene Designer. When the DEM data is brought into one of these programs a visual view of the elevations are represented by different colors or shades of grey. The elevation color pallet can be changed for the effect you see on the map and that is represented by the Color Key graphic.
The large map is rendered into an image we can bring into Photoshop where additional work has been done. Note that the raw image of this map file is many times larger than your computer screen and over 40 Megabytes in size.
Geographic Information System (GIS) digital map files were provided to Mountain Visions by the Upper Sevier Watershed. These contained the outline boundary of the watershed, the outlines of the sub-watersheds and the river systems. These also included the boundaries of the Cedar Breaks National Monument and Bryce Canyon National Park. The GIS maps were layered on top of the DEM map terrain features and the desired boundaries and rivers were traced in Photoshop.
A copy of the large image was reduced in size to fit on this web page and text names were placed on the map using Photoshop. The shading transparency on the outside boundaries of the Watershed, the small graphic outline of Utah with the location of the watershed and the arrow pointing North were also done with Photoshop. As you roll over each sub-watershed a glow effect will appear. The glow and rollover effects were created in Photoshop and Image Ready.
