Abstract: Abstract: A VideoGIS system aims at combining geo-referenced video information with traditional geographic information in order to provide a more comprehensive understanding over a spatial location. Video data have been used with geographic information in some projects to facilitate a better understanding of the spatial objects of interest. This paper presents an on-going VideoGIS project, in which scalable geo-referenced video and geographic information (GI) are transmitted to GPS-guided vehicles. The hypermedia, which contains cross-referenced video and GI, are organized in a scalable (layered) fashion. The remote users can request, through 3G mobile devices, the abundant information related to the objects of interest, while adapting to heterogeneous network condition and local CPU usage. Available bandwidth estimation technique is used in the adaptive video transmission. [Copyright &y& Elsevier]
