Getting Started with IDL: 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.
In this chapter, we will enter statements at the IDL Command Line. This demonstrates IDL's interactive capability, and shows how easy it is to manipulate your data.
| Note To simplify obtaining useful results from the examples in this manual, create a bitmap buffer for your graphic windows and to use a maximum of 256 colors by entering the following command at the IDL command prompt: DEVICE, RETAIN=2, DECOMPOSED=0 |
