2.5.1 Accuracy Check for Shape Cutting

New Version of Saga:  Usually a new version of Saga is quickly assimilated into these exercises.  The latest release, Version 2.1.2, is so radically different that it will take some time to catch up with revised exercises.  Please email me immediately whenever you find an old exercise that simply cannot be accomplished in the new Saga, due to big changes in the properties, etc.  I will try to provide fixes within about 2 days.

  • Exercise Title:  Accuracy Check for Shape Cutting

  • Author:  Murray Brown

  • Version:  February 2013

1. Display on a map the Liberia point shape (from the World Ocean Database) you created in Cutting a Shape to the Project Map Extent in Saga The name of the shape you created is temp_liberia_annu_woaselect_saga.shp.
2.  Plot the Liberia graticule on top of the temperature point shape.  It should look like this, when the circle sizes are adjusted.  [Ignore the colors.]
