Educating the Public Using Geospatial Technologies
How Can I Illustrate the Severity of the Problem?


Three-dimensional perspective of a tamarisk infestation. This 3D perspective of a tamarisk infestation (coarsely-textured, darker red vegetation), created from color-infrared satellite imagery draped over a digital elevation model, dramatically illustrates the extent of the infestation.
Educating the Public
Education and effective communication are key components of successful weed management programs. An educated public will help prevent weed spread and informed cooperators and agency line officers will be more likely to fund and assist with weed management efforts. Pictures and visualizations are some of the most motivating and effective communication tools available.
Geospatial Educational Tools
Viewing weeds data, aerial photographs, imagery, or maps in three dimensions rather than two gives new perspective and can provide insight that may not be apparent otherwise. Static (as seen in the box on the right) and animated 3D visualizations can be powerful educational tools. Learn to create visualizations [PDF]...

Animating photo point photographs to show change over time is an easy, yet impressive method to illustrate the impact of weed invasion or the results of weed treatments. These animations are easily produced in PowerPoint. Learn how [PDF]...
