CHINA BOUND: A Guide to Academic Life and Work in the PRC
ously, the cost of satellite imagery generally precludes optimal detailed coverage, but in many cases, one or two scenes are superior to even the most detailed of available Chinese maps.
In the past five years, Global Positioning Systems (GPS) have begun to augment, if not replace, more traditional compass-based orienteering techniques in the field. While GPS continues to be a relatively expensive technology, prices are rapidly dropping; some systems (such as the AccuNav by Eagle) sell for under $900. In areas such as China, where high-quality maps are largely unavailable, the combined application of satellite imagery and GPS technology may ultimately prove superior for nearly all cartographic needs.
