Exercise 3. Spatial Analysis Exercise2 GIS in Water Resources Fall 2016 Prepared by Ayse Kilic - revised Oct. 8, 2015 Goal The goal of this exercise is to serve as an introduction to Spatial Analysis with ArcGIS. Objectives Calculate slope from a gridded digital elevation model Apply the model builder geoprocessing capability of ArcGIS to program a sequence of ArcGIS functions Use raster data and raster calculator functionality to calculate watershed attributes such as mean elevation, mean annual precipitation and runoff ratio. Interpolate data values at points to create a spatial field to use in hydrologic calculations Computer and Data Requirements To carry out this exercise, you need to have a computer that runs ArcGIS for Desktop 10.3.0. The necessary data are provided in a zipped file (Exe3Data.zi) at the course web site: Readings Handout on "Computation of Slope" at http://snr.unl.edu/kilic/giswr/2016/Slope.pdf
