Description
Technical field
The present invention relates to a kind of engine map and cell phone map mobile-terminal platform that is embedded in portable terminal, refer in particular to a kind of engine map and cell phone map mobile-terminal platform that is used in the portable terminal handling based on GIS data that be embedded in.
Background technology
Along with the continuous progress of society, the people's activities scope is increasing day by day, and location-based business is also being accepted by the user gradually and popularized.The while development of wireless communication devices, cordless communication network can provide the positioning function of different accuracy, as Cell-ID, E-OTD, A-GPS etc.And the popularity rate of radio communication is also in continuous improve, and therefore, the wireless terminal of domestic consumer by carrying by cordless communication network, promptly can use location-based related service, as: functions such as location, information point inquiry, navigation.
In the prior art, in the implementation based on wireless network, present attainable approach has short message mode, multimedia message mode, WAP browsing mode, the existing position-based service business that provides on portable terminal is not to develop at location service, give user's impression bad, can not offer the user is accurately true, both pictures and texts are excellent spatial information and attribute information thereof.Short message mode is meant the user by sending format information to service code, and sms center or sms sp in conjunction with user position information, are issued the user with the result by text mode according to request content.The shortcoming that this programme exists is that user's business impression is bad, and word content can't can be given user's direct feel as map.The multimedia message mode is meant the user by sending format information to service code, and MMS center or multimedia message service provider in conjunction with user position information, issue the user with the result by text or graphics mode according to request content.The shortcoming that this programme exists is that user interface is friendly, professional inadequately, and interactivity is poor.The WAP mode is meant that the user by visiting corresponding location service website, browses map, query-related information.The shortcoming of this programme is that the WAP browser is not at the location service exploitation, does not support vector graphics; Use step comparatively miscellaneous, user experience is friendly inadequately.
The mankind have entered the information age, and developing rapidly of IT industry and communications industry strides forward the mankind to so-called " TIMES " (Telecommunications, Information-technology, Multimedia, Entertainment and Security).Along with the mobile communication transmission technology upgrades to 2G, 2.5G, 3G from the first generation, and will develop to faster data transmission speed, world-class software developer is by cooperating with mobile phone production major company, some functions of computer are added on the mobile phone, make it except transmitting acoustic information, data and images serve can also be provided, make mobile phone progressively become " removable computer ", " wireless network ".And under the integrated leading trend that becomes application, GIS provides spatial analysis and visualization function for all basically computing environment.
(Geographic Information Systems GIS) has incorporated information technology (Information Technology, main flow IT), and become the important component part of IT to GIS-Geographic Information System.The fast development of GIS technology makes people contact more and uses it.For example electronic chart, based on public multimedia shopping guide's guide system of Internet, automobile GPS is from navigation system or the like, everything all makes requirement of geographical information increase sharply.GIS merges computer graphical and database in one, the new and high technology of storage and processing spatial information, it organically combines geographical position and association attributes, according to user's needs with spatial information and attribute information is accurately true, both pictures and texts are excellent exports to the user, satisfy urban construction, engineering survey, construction and people requirement to spatial information, by its exclusive spatial analysis functions and visual expressive function, carry out various aid decisions.The These characteristics of GIS makes it to become and the bright right different advanced tools of dealing with problems of traditional analytical method.
Along with the communication network big capacity and the high speed of (comprising wired and wireless network), GIS has become the distributed heterogeneous system on network.By WAP server and mobile GIS, the LBS and the MLS that have risen at present are location-based service and Location based service, have reflected this variation tendency highlightedly, and promptly GIS becomes everybody information service instrument of possessing of the whole society.The user is increasing to realize the GIS demands of applications on portable terminal, and therefore offering each mobile phone users based on the cartographic information service of GIS becomes trend.At present existing more than 200,000,000 cellphone subscriber of China, if be 10 yuan of expenses of MLS payment in everyone every month, the output value in 1 year in the whole nation will reach 24,000,000,000.Can predict that in the near future the geography information service can be carried out 4A service (geo-in-formation for anyone and anything at anywhere and anytime) whenever and wherever possible for anyone and anything.Therefore, proposing portable terminal map platform on portable terminal realizes providing service to the user.
Mobile GIS (GIS-Geographic Information System), to be the client obtain the various required information in each family with geographical attribute such as traffic, commerce, food and drink, amusement, hospital of the geographical position at its place and periphery thereof by wireless communication tool to this application, has broad application prospects.But existing GIS engine can not be supported a plurality of mobile terminal operating systems, and data structure is compact inadequately and do not have an interface that can call alternately with browser; Because in the face of service provider, the professional column of constantly change, the attribute information of object, GIS engine can not satisfy the management of this respect transition information and show.Therefore, the GIS engine that needs the expansion traditional sense.
