VISUALIZATIONS

The geovisualizations seen here have been produced using geospatial datasets, including satellite imagery, and the following software packages:

ArcGIS, ERDAS Imagine, ENVI, 3D Nature Studio, Adobe Photoshop, Adobe Premier and Microsoft Movie Maker

The visualization shows the digital elevation model ( DEM ) of the James River Basin . The James River is indicated in blue and a red line represents the James River Basin boundary.

This fly-through begins in the north-east corner of the James River Basin at the headwaters near Marshfield, MO, and heads south-west following the path of the river towards Table Rock Lake. The visualization fly-through was made at a low (left image) and high (right image) altitudes.

The growth of the city of Springfield (in yellow) as captured by Landsat satellite imagery from 1972 to 2000 is shown in the following visualizations: Additional movies capturing this concept are also available:

Satellite imagery showing change in Springfield , MO. The growth of Springfield , MO , from 1972 to 2000 is shown in yellow, forested areas are shown in dark red, areas of vegetation are shown in pink and water bodies are shown in blue. (0.2 GIF format)
These satellite images were re-classified to show the forested areas in Springfield, MO (indicated in green) at slow (3MB WMV format) and faster speeds (3MB WMV format)
Urban and forest cover change in Springfield, MO. The satellite images were re-classified to show the forested areas in green, the urban areas in red, water bodies in blue and all other land-use classifications as a no-color background. (4MB WMV format)
Land use change in Springfield, MO. This visualization shows all land-use classifications: water bodies (blue); forest (green); urban (red); crop & farmland (orange); bare & sparsely populated (pink) at slow (5MB in WMV format) and faster speeds (5MB in WMV format)

Fly-through of the James River Basin using a 2002 Landsat satellite image and DEM. The James River is represented in blue and the red line represents the James River Basin boundary. The visualization fly-through begins in the north-east corner of the James River Basin near Marshfield, MO, and heads south-west following the path of the river, before turning at Springfield Lake to look over the city of Springfield. (31MB AVI format)

Fly-through of the James River Basin where a topographic map overlay was draped over the DEM. The James River and Table Rock Lake are represented in blue and the James River Basin boundary is represented by the large red wall. The visualization fly-through begins at Table Rock Lake in the south-west corner of the basin and heads upstream towards the north-eastern boundary of the basin. (37MB AVI format)

This visualization follows the path of Wilson's Creek as it travels through part of Wilson's Creek National Battlefield. The land-use classifications were taken from Landsat imagery and the trees were randomly placed throughout the park according to land-use classification. (36MB AVI format)

Fly-through of Wilson 's Creek National Battlefield. A different land cover color mask is placed onto the DEM to represent each different present day land-use type. The trees shown in the visualizations are models representative of trees that exist in that

physical location; these trees are believed to have been in existence during The Battle of Wilson's Creek. Multiple visualizations were created through the use of a database query where trees were selected according to their diameter.

Visualization showing the forest cover change over time near the intersection of Highway 65 and the James River Freeway. The visualization starts in 1972 and finishes in 2000 and the temporal change is represented as 1 year every 2 seconds.

The James River and Springfield Lake, in the background of the image, are represented in blue. The forested areas are shown in green, and the remaining land use cover types are shown in grey.(74MB AVI format). The second visualization covers the same time period at the same rate of change and focuses on the trees within the forest at a greater detail. (73MB AVI format).

Visualization showing the urban growth of Springfield, MO over time. The visualizations represent 2 years every 1 second. The visualization begins by showing the full extent of Springfield, MO, in the year 2000 and rewinds the urban growth of

Springfield from 2000 back to 1972. After reaching the year 1972, the view zooms in to the intersection of Highway 65 and James River Freeway and the urban growth is now shown from 1972 to 2000. The James River and Springfield Lake are represented in blue, urban areas are represented in yellow, and the remaining land-use cover types are shown in grey.(8MB AVI format) The second visualization focuses on the intersection of Highway 65 and James River Freeway, showing the urban change from 2000 back to 1972 and then back to 2000, at the rate of 2 years per second. (150MB AVI format)

Animated visualization showing the urban growth of Springfield, MO over time. The growth of Springfield is simulated by sample houses that grow relative to Springfield's rate of urbaniztion. The visualization is focussed on the area immediately north of Lake

Springfield, showing the urban change from 2000 back to 1972 and then from 1972 forwards to 2000, at the rate of 2 years per second.(11MB AVI format). The second visualization also focusses on the area immediately north of Lake Springfield over the same time frame from a planimetric (bird's eye) view. (9MB AVI Format)

This visualizations shows forest cover change on Wilson's Creek in Wilson's Creek Battlefield. The left image shows pre human settlement land cover and the right image shows present land cover.

Visualizations showing the land cover change in the James River Basin. The left image shows the 1972 land cover and the right image shows the 2000 land cover.

The visualizations begin on Highway 65 (left hand edge of the screen) in Ozark and head north towards the intersection of Highway 65 and James River Freeway. After reaching the intersection, the view briefly looks to the north-east before swinging left to overlook the city of Springfield and Springfield Lake. The view then returns to overlook Highway 65 and travels south back towards Ozark. The urban areas are represented in yellow, forested areas are represented by the trees, croplands are represented by the raised beige fields, water bodies are represented in blue and bare areas are represented in purple.

GLOSSARY

Contour Lines	Lines connecting a neighborhood of points that all lie at the same elevation and thus illustrate topography on a map.
DEM	The digital representation of a topographic surface, usually a raster grid of spot heights.
Land-use Classification	The process of analyzing a study area and determining and defining how the land that constitutes said area is used; for example urban, agricultural, range, forest, water, wetland, barren, tundra, and perennial snow and ice
Satellite Imagery	Images of the earth's surface that are obtained by satellites orbiting the Earth.
Topographic Map	Printed maps that include a vast range of information including contour lines (to show elevation) and symbols to represent relevant features (such as streets, buildings and waterways).
