Labeling Dense Maps for Location-Based Servicesier than sparse ones, so that free spaces were allotted to dense features before consumed by sparse features. An efficient algorithm was developed for map labelling in real time. We implemented this method in a Java environment. A case study shows sound cartographic results and acceptable efficiency of the labelling.

Location-Based Tour Guide System Using Mobile GIS and Web CrawlingFor the purpose, it is important to extract semantically relevant geographical information from the Web and efficiently present it to mobile users. In this paper, we present an effective LBS approach based on advance Mobile GIS and Web technologies. We design and implement the prototype of the Tour Guide System as a motivating application of LBS.
