Sun path chart program

< http://solardat.uoregon.edu/SunChartProgram.html>

citation from University of Oregon, Solar Radiation Monitoring Laboratory.
-----------------------------------------
This program creates sun path charts in Cartesian coordinates for: (1) "typical" dates of each month (i.e.; days receiving about the mean amount of solar radiation for a day in the given month); (2) dates spaced about 30 days apart, from one solstice to the next; or (3) a single date you specify. You can select whether hours are plotted using local standard time or solar time. In addition, there are a number of options available to allow you to alter the chart's appearance. Resulting charts are displayed in your Web browser window, and they are meant to be printed out. Two formats are currently available: PDF (Adobe) and PNG (a standard international graphics format). The create sun path charts in polar coordinates go to the polar sun path charts Web page. For more information, visit our Web page about using sun charts.

GIS textbook

Beyond Mapping III
(Compilation of Beyond Mapping columns appearing in GeoWorld magazine 1996 to 2007)

Easy to understand with various pictures. All the pages are downloadable, though it is sold as a book. Many concrete examples of the objective, quantitative and exhaustive approach are described with easy-to-understand pictures.
It is used as a textbook of the lecture at Harvard "Advanced Workshop in GIS"(Instructor: Sumeeta Srinivasan; Spring 2008). Using this book as a textbook of a lecture seems very good.
