A must read for all GIS professionals! A short quote to get you hooked:
“She [Gladys West] rose through the ranks, worked on the satellite geodesy, and contributed to the accuracy of GPS and the measurement of satellite data. As Gladys West started her career as a mathematician at Dahlgren in 1956, she likely had no idea that her work would impact the world for decades to come.”
Despite the ubiquity of GPS and her role in developing it, West still prefers to use a paper map when she travels. For someone accustomed to trusting their own calculations, some old habits never die.
