MapPlot example 2
How to control individual map areas
This example can be created using HLU C or HLU FORTRAN library calls or NCL. It demonstrates how to highlight and emphasize certain areas of a map through the map projection, limits, and masking areas. The names of the source files for this example are mp02c.c, mp02f.f, and mp02n.ncl.
Discussion
This module discusses how to create this example using HLU function calls and a resource file. The resource file used in this example is called mp02.res.A detailed discussion of how this example works appears in its source code.
Creating the plot using HLUs
The HLU C program that generates this plot is called mp02c.c.
Creating the plot using HLU FORTRAN library calls
The HLU FORTRAN program that generates this plot is called mp02f.f.
Creating the plot using NCL
The NCL script that generates this plot is called mp02n.ncl.
The data
This plot does not use any external data.
