This paper addresses the problem of closing the loop from perception to action selection for unmanned ground vehicles, with a focus on navigating slopes. A new non-parametric learning technique is presented to generate a mobility representation where maximum feasible speed is used as a criterion to classify the world. The inputs to the algorithm are terrain gradients derived from an elevation m...

For nearly 30 years, since its introduction onto corporate management scene in the early 1970s, strategic planning has been on a roller coaster ride. Nearly a decade later strategic information systems planning was put on the same track but that does not mean we have to stay on the same track or that we have to take it at the same speed.

Most of public travel information services nowadays are limited to the driving navigation or bus/subway guidance. Practical needs for pedestrian navigation yet haven’t got met enough and usually result in unacceptable travel route planning. This paper presents an approach on building Walkway network with different map layers for pedestrian specified facilities, and then implements pedestrian ai...

Road feature is one of the most important features of urban. The change of road reflects construction speed of an urban. map road updating timely and exactly becomes an urgent issue. Current method updating of road feature is carried out complete manually, and has the disadvantage of tending to lose changed road and low automatic level. The updating of map road feature including two parts: one ...
