Install and Run G.Projector

Depending on your operating system and how you have it set up, installing G.Projector may be as simple as double-clicking the GProjectorJ archive icon on your desktop. If not, then you may have to use the appropriate command-line call from the shell.

The GProjector archive contains a folder called GProjectorJ which holds the following items:

• The G.Projector.jar file
• Sample source map images in a folder called "sample_maps".
• A README file.

Again, depending on your operating system, you may be able to launch G.Projector by simply double-clicking on the G.Projector.jar file. But if that desn't work, then you would need to launch from a shell command line by typing:

java -jar G.Projector.jar

If you expect to deal with a high-resolution dataset — for example a lon-lat array gridded at finer than 1° resolution — then you should change the above command to include an option instruction to Java to use more memory. The following should suffice:

java -Xmx128m -jar G.Projector.jar

That will grab 128 MB of memory rather than the default 64 MB. If you have memory to burn then you might up the limit to 256 MB via:

java -Xmx256m -jar G.Projector.jar
