Recently, three colleges converged in western Nevada for four days of field paleontology. Over thirty students participated in a series of field tasks that represented different kinds of field scientific work. The tasks ranged from classic description to modern collection techniques. For the latter, the students mapped a trilobite-rich area using a [...]

Glossing over the semantically misleading title, the report did a decent job of quickly summarizing the obvious—navigational software is prone to errors. It is not that the receivers are inaccurate, but rather the GIS programming behind [...]
In the last blog, I gave an introduction to dilution of precision or DOP and explained when you need to know it and when you don’t. This time, I want to show you a very cool, free program to calculate your DOP values throughout the day. All you need to know is your [...]
