GIS with Logbooks


Data sets

You will use the following data files. The program will automatically get them if they are not present, and place them in c:\mapdata\database.

Data File Description
CLIWOC ships Calculated ship heading and speed, computed daily.  This data set has the ship velocity with polar coordinates (KNOTS and HEADING).  If you think metric, you can get the SPEED_KPH.
Global_winds Current wind averages by month from NOAA's Earth System Research Laboratory. This data set  has the winds with u and v (x and y) components, in meters/sec (1 m/s=1.94 knots). 
Modern piracy incidents NGA ASAM database of recent piracy.  This shows current piracy world wide, starting in 1978.
Somali piracy Subset of the NGA ASAM database of recent piracy.  This shows events well offshore in the Indian Ocean.


Create a single map that best shows the shipping lanes in the 18th century in the Indian Ocean.  Put a caption to explain it.

Create a table describing the key characteristics of the three shipping lanes.  You can embed small figures in the table.  Put a caption on it.

Write single clear and concise paragraph relating the 18th century shipping lanes to 21st century piracy in the NW Indian Ocean (well off the coast of Africa, in the subset data base), and both to climate.  Refer to the figure and the table in your discussion  You can include one other figure if you want.  Your discussion should indicate that you did the reading about the French ships in the East India trade, and how we use logbooks for reconstructing the trade routes.

Email the instructor your Word document.


Table with figures for each entry, created in Word.  Note that this combines text and figures

Additional Data File Description
Climate options to get CLIWOC weather CLIWOC 2.1 database.   This has locations of the ships, generally daily, and weather observations.  This data set  has the winds with polar coordinates (WIND_SP and WIND_DIR).
