GMT Examples and Hints
This is my general information page about the Generic Mapping Tools (GMT) software which I use to create various graphs.
- Technical Reference and Cookbook
- The technical reference and cookbook documentation is included in
the basic GMT distribution. If you don't feel like downloading the
entire thing just to get that here are the sections of that reference.
- Chapters 1 to 4 (382 Kb)
- 1. Prefaces
- 2. Introduction
- 3. GMT overview
- 4. General features
- Chapter 5, Sections 1 to 3 (994 Kb)
- 5. GMT projections
- 5.1 Non-map projections
- 5.2 Conic projections
- 5.3 Azimuthal projections
- Chapter 5, Sections 4 to 5 (1018 Kb)
- 5.4 Cylindrical projections
- 5.5 Miscellaneous projections
- Chapters 6 to 7 (136 Kb)
- 6. Cook-book
- 7. Mailing lists, updates, and bug reports
- Appendices A to D (35 Kb)
- A. GMT supplemental programs
- B. GMT file formats
- C. How to make GMT Encapsulated PostScript Files
- D. Availability of GMT and related code
- Appendix E (149 Kb)
- E. Predefined bit-and-hachure patterns in GMT
- Appendices F to J (136 Kb)
- F. Chart of Octal Code for Characters
- G. PostScript fonts used by GMT
- H. Hints and known bugs concerning display of GMT PostScript
- I. Color Space - The final frontier
- J. Filtering of data in GMT
- Appendix K (375 Kb)
- K. The making of the GMT High-Resolution Coastline Database
- Chapters 1 to 4 (382 Kb)
- GMT Man Pages in PostScript
- The documentation in the GMT Technical Reference and Cookbook can be frustrating at times. The man pages are a good source of additional documentation. I've converted all of the man pages into a single PostScript document that can be sent to your favorite printer if, like me, you still prefer hard copies of documentation. The individual man pages are also available in PostScript format.
- Example Scripts
- A series of example scripts ranging from the simple to the complicated (or at least they will eventually).
- Makefile for Linux Elf
- A different makefile from the one in the standard distribution. This one will compile the software and make the libraries in Linux ELF shared library format.
- Distribution Examples
- I've created thumbnail pictures of the 14 examples that are included with the GMT distribution. You can browse through these for ideas, and if you find one close enough to what you need you can obtain the job script and appropriately modify it.
- Colors
- The GMT software allows colors to be specified in plots via the RGB system wherein a number between 1 and 255 is specified for Red, Green, and Blue. I've put together some pages that have various shades of some colors (just blue for now), their names, and their RGB values to making choosing colors a bit easier.
