“…Nevertheless, the limited bandwidth [6,15,26] affects the performance of the application if large amount of data is to be transferred from the server. Follin et al, [9] suggests that it is essential to optimise the amount of data that has to be transmitted and displayed on mobile devices. The users' interests of obtaining the piece of information omit the presentation of other trivial data.…”

“…The block using the method of the vector in the same amount of space GIS data condition shows some improvement on the rate [4]. With the development that handheld computer (PDA), mobile phones, and other smart devices can support higher color resolution and have more computing power, mobile location service system needs to start more graphic images in the form of electronic maps to provide users with different levels of detail and more scale representation of information [5,6]. Established a navigation database system for the application requirements of intelligent transportation and location-based services [7,8].…”

Document management is a usual way to organize spatial data in mobile terminals. And the compressed CGML spatial data has been widely used in location based services. Referring to the thoughts of map set in cartography, nine closely connected and equal sized rectangles are used as the scope for requesting mobile map data, and these nine closely connected rectangles are built to be nine tiles model. Therefore, in view of the method of block requesting and storing on mobile spatial data following nine tiles model, as well as the large quantity of mobile spatial data and its complex geometry relation, this paper puts forward the construction mechanism of nine tiles model and cache organization of CGML spatial data in mobile terminals that abide by nine tiles model. This way of organization and management of mobile spatial data is good to increase the efficiency of heavy spatial data accessing in the low band and reliability of wireless network environment.

“…This has a similar flavor as JPEG compression for images, where significant coefficients are transmitted earlier and insignificant ones are transmitted later, or even dropped without much impact to the image quality. The idea of multi-resolution LOD has also been applied recently on the visualization of spatial data [7]. With multi-resolution transmission, a user could decide early to discontinue with the transmission of an irrelevant document.…”

Multi‐Resolution Information Transmission in Mobile Environments

Abstract. Mobile environments are characterized by low communication bandwidth and frequent disconnection. Conventional information retrieval and visualization mechanisms thus pose a serious challenge to mobile clients. There is a need for these clients to quickly perceive an overall picture of the information available to them, so as to enable them to discontinue the transmission of information units that are unlikely useful to them. We had proposed a multi-resolution transmission mechanism for web documents. In particular, various organizational units of a document are transmitted to a mobile client in an order according to their information content, thereby allowing the client to terminate the transmission of a useless document at an earlier moment. In this paper, we generalize the multi-resolution transmission model for a document, and then extend that model into the multi-resolution transmission framework to cater for not only units within a document, but also for a collection of documents. We refer to the multi-resolution transmission mechanism for a particular document as intra-document multiresolution transmission mechanism and the extension to a document cluster as inter-document multi-resolution transmission mechanism. With the integrated multi-resolution transmission framework, a mobile client can examine the important portions of the document cluster for an early grasp of the information therein, with the most important contents for each of those documents more readily available as well.
