Elevation data in raster format is readily available and widely used in a GIS for visualization and analysis. This course teaches how to use ArcGIS Spatial Analyst tools to derive new raster data from an elevation raster in order to accurately model the earth's surface, solve problems, and support decision making for a variety of applications.
Who Should Attend
- GIS analysts, specialists, and other experienced ArcGIS users who need to visualize terrain landforms and perform raster-based analyses.
- GIS professionals working in industries such as utilities and communications, energy, agriculture, environmental management, mining, forestry, and emergency management may find this course of particular benefit.
Learn How To
- Derive slope and aspect surfaces to quantify terrain steepness and exposure to atmospheric phenomena.
- Determine if the resolution of a raster surface is appropriate for terrain analysis at the required map scale.
- Identify locations in an area of interest that meet elevation, slope, and aspect criteria.
- Create a hillshade surface and combine it with an elevation surface to create a visually appealing shaded-relief map.
- Generate contour lines to represent elevation measures on a map.
- Create a viewshed raster to identify areas that are visible and areas that are not visible from one or more surface locations.
