Creating and Analyzing Surfaces Using ArcGIS Spatial Analyst

ArcGIS Spatial Analyst provides tools for advanced raster analysis. Using ArcGIS Spatial Analyst, you can model a variety of real-world scenarios to create new data, analyze complex terrain attributes, and solve problems. In this course, you work with elevation rasters and other data to model surfaces, evaluate results, and create a variety of maps that inform decision-making.

This course is designed for GIS analysts and experienced ArcGIS users who perform raster-based spatial modeling and analysis. Those who need to conduct the analyses listed below or similar analyses will benefit:

• Find suitable locations for new development.
• Site cellular and radio towers and map potential relay tower sites.
• Find low-visibility locations for storage tank farms.
• Find optimal locations for vineyards, ski slopes, and other applications that have site slope and aspect requirements.
• Determine lines of fire for military fortifications.
• Predict fire risk.

After completing this course, you will be able to:

• Use different interpolation methods to create surfaces from sample data and evaluate the results.
• Calculate density.
• Create hillshade, shaded relief, and contour maps.
• Calculate slope and aspect.
• Calculate visibility surfaces and viewsheds.

• Getting started with surface analysis: How to represent surfaces; Sources of topographic data.
• Interpolating surfaces: Interpolate surfaces from point data using the IDW, Spline, Kriging, and Natural Neighbor methods; Specify a barrier.
• Preparing the analysis environment: Set workspaces and extent; Clip a raster to a display area; Create two overlapping rasters; Combine rasters; Use a mask.
• Calculating density: Feature density estimation; Simple and kernel density calculations; Use attributes to calculate density.
• Analyzing surfaces: Create hillshades; Create contours; Calculate slope and aspect; Calculate visibility and viewshed.

You should have completed ArcGIS Desktop II: Tools and Functionality or Learning ArcGIS Desktop or have equivalent experience. If you are new to raster data, completion of Working with Rasters in ArcGIS Desktop is recommended.

This course is designed to work with the following software:
