A geographic XML-based format for the mobile environment

Abstract

The rapid emerging of mobile Internet provides new opportunities for information services. One of the service types is tied to mobile location technology that allows defining the geographical location of a mobile user. It enables the development of new class geographical information services. Location-based applications require careful development of the general architecture as well as a data format for information transfer due to restrictions of mobile devices and wireless data networks. In this paper, we examined a use of different format types in mobile information services for the representation of geographical information. Then, we propose to use an XML-based data model language for geographical information description in such systems. We describe the logical structure for the new format and basic tags. We expect our format helps in effective development of geographical applications for the mobile environment.

MAGGIS: A Mobile‐Agent and GML Based Distributed Geographic Information System

“…Recently years, increasing research has been done to employ GML in GIS applications. [17] reports a prototype that wraps and visualizes geographic data in distributed environment by using XML technology; [18] introduces a XML-based mediator for heterogeneous GIS query; [19] gives a XML-based approach to integrating GIS and tourism information; [20] proposes a GML format to represent moving object in mobile environment; and [21] and [22] present a specification of a spatial query language over GML and the query processing approaches. [23] studies XML technologies and its usage for GML by evaluating several approaches of XML storage using both structured storage and unstructured storage in XML-enabled database systems, native-XML database systems and hybrid storage methods respectively, and concludes that Oracle XML DB does fit for GML storage and but it does not support spatial query processing.…”

“…[16] described the AX-IOMAP system, which is a Web map publishing kit and a customizable virtual map interface that allows for the display and manipulation of multiple point, line and area layers, database query, choropleth mapping, hyperlinking, map labeling and annotation. To render maps in a Web browser, AXIOMAP generates VML shapes "on the fly" from XMLencoded geographic data that can physically reside on different servers; [17] utilized XML-based mediation to integrate heterogeneous sources of GIS and imagery data, and query evaluation and presentation planning in spatial mediator were also studied; [10] proposed a geographic XMLbased format for the mobile environment; and [18] reported a prototype that wraps and visualizes geographic data in distributed environment by using XML technology. Since GML was put forward as a specific kind of XML-like languages for encoding geo-referenced data, there has been seen more research work focusing on using GML for representing and querying geo-referenced information.…”

Designing adaptable geographic objects for mobile applications

“…Web Cartography [15] and cartography services [24] are now widely used. New architectural approaches to build service-based applications (using Web services for example) gave more impulse to this trend and the emergence of standards for interoperability such as GML [6], [7], made it feasible.…”
