IDL and Mapping

IDL's mapping facilities allow you to plot data over different projections of the globe. This chapter shows how to display various map projections and plot data over them.

The first part of this chapter demonstrates the mapping capabilities of the Tool Palette and the iMap tool. The second part discusses how to work with direct graphics statements at the IDL command line to demonstrate IDL's interactive mapping capability.
