GEOG 373 Applied Climatology Lab.Laboratory 2: Introduction to SAGA GIS and a slope radiation exercise. (49 marks total)This laboratory has two main learning objectives:1)Gain familiarity with entry-level operations in SAGA GIS.2)Begin examining in detail the implications of local geometric controls on radiation receipt.Data for this exercise are posted on the Coursespaces website. There are two ZIP files and a PPT with instructions. Use SAGA and the “Elevation Layer” to perform analyses to perform these tasks and answer the following questions:1) (5 marks) Determine the following values for the Elevation Layer. Note that you may not be able to find this in the information SAGA displays – where else can you look? a) Projection: b) Datum: c) Spheroid: d) Latitude of standard parallel #1: e) Central meridian:2) (3 marks) What are the min/max elevation values, and corresponding range of the DEM?3) (4 marks) How many rows/columns? What is the cell size (with units) ? Where do these cells start (lower left) in terms of map units (not degrees)?
