GMT (Generic Mapping Tools)

Here are some links to interesting GMT pages:

• Map of Atlantic Mid-Ocean Ridge
• Map with Symbols
• World Earthquake Map
  Notice that the script accompanying this map actually fetches fresh updated data from a web page!
• Plotting Data on a Map
• Gridded Surface Data
• A 3-D Bar Graph
• The following examples are from Phoenix Bedrock Topography, my final project from when I took Computers in Geology in 2002.
  • Map of Arizona
  • 3D Plot Showing Depth to Bedrock
  • The Same 3D Plot in HoloDraw
  • Plotting a Surface over Gridded Data
• Another GMT Surface Plot
• The Same Data in HoloDraw
• A 2-D Line Graph
  Although this graph is not incredibly complicated, imagine making it with Microsoft Excel. Go ahead, think through the steps you'd follow... Then, imagine updating it every day as new stock prices come in. Using Unix and a GMT script, the updating could be 100% automated!
