摘要：Although location is now a common part of mobile computing for consumers, there is a class of much more demanding applications wecan call “high stress GIS.” These apps are time-critical as well as business-critical; they have to work whenever and wherever they areneeded, and there are significant consequences when they don’t. This paper employs a specific type of user, the utility field crew, toillustrate the architectural issues that must be addressed in this kind of application. These users work at the edge of the enterprise, relyingon hardware platforms and communications networks that are not optimal for the demands of a high-performance GIS. Complex datasets, covering a large geographic area, have to be kept updated and made available to crews that are spread around the utility’s servicearea. In the aftermath of storms, wireless communications networks may be unavailable, making it hard to update important data justwhen it is needed most. These systems play a vital role in managing our critical infrastructure so - despite these challenges – it isimportant that we can make them work. The paper outlines a number of these design challenges and suggests solutions that have beentested in current mobile applications
