Friends who often play with GPS will definitely be very familiar with the positioning navigation application. Relative to the affiliated video game function is relatively familiar, but it is always necessary to fool some of the small and practical functions in the navigator. Today, Xiaobian is here to talk about the service function of the location.
This article refers to the address: http://
Location Based Service (LBS), which acquires location information (geographic coordinates) of mobile terminal users through a telecommunication mobile operator's radio communication network (such as GSM network, CDMA network) or external positioning method (such as GPS). Or geodetic coordinates, a value-added service that provides users with corresponding services, supported by the GIS (Geographic Information System) platform. In the traditional navigation device, it is commonly found in the navigation low-pass peripheral search. It can search for nearby famous buildings, leisure and entertainment places, and catering services through GPS positioning. In the confident Android smart navigation device, this kind of navigation The application of LBS has been further expanded, not only for individual single-machine retrieval, but also for a network identity SNS (Social Networking Services). What are the differences and advantages between the two? The following will give you a explanation.
For the peripheral search in the Navigator, we take the Kay LiDE navigation map as an example. In the operation interface of the map, click the surrounding button below to display the corresponding search requirements. The rider can select by means of on-demand selection. The number of search results depends on the detailed level of the consultation point of the map, which is what we often call the navigation map POI (Point of Interest). The remarkable feature is that the interest point belongs to the offline information information, which is fixed. Existence, the search process does not require too much waiting, as long as the upgrade and update of the map can get the latest and most complete POI, you can also get the real-time information about the surrounding buildings, you can easily find what you need. Not only provide your food, clothing and accommodation, but also add the corresponding points of interest in the navigation settings, you can directly see the surrounding information on the map information during the driving process.
POI on the map
Intelligent peripheral search
The service of LBS first appeared in the network. The netizens familiarized themselves with the environment around the destination before going out to play. With the rise of the Android intelligent system, more application software developed based on the Android platform pushed the LBS service to the forefront. As the current hotter: public comment, grand cut, fifty steps, etc., the common feature is to obtain information through communication traffic or 3G network, in the application process of software, each user can pass Account registration to get a unique logo of their own, then to comment and share the places they have been to, and the current hot sign-in function, through the number of check-ins to find the most frequent places to find like-minded friends in the near future, a disguise Dating mode. In addition to easy searching, LBS services can also implement many group purchase applications through online online functions.
Cut user reviews
Comments: The navigation map surrounding the search and LBS Android application, the common point is to serve the public, in the shortest time to familiarize users with the surrounding environment, find their desired destination. The difference between the two is also obvious. The navigation map retrieval is based on the GPS module search star positioning to determine the location, while the POI point of interest is offline mode, the relative search is faster and more convenient, but the information update depends on the map manufacturer. The update is a single-person service for more cars; while the LBS-based software is connected via GPRS traffic or 3G network, which is an online real-time application, during use, More is an interaction with friends, through the sharing of comments between friends can quickly understand the practicality of the place to go is not high, but the use of the process will generate traffic bills. The length of the two is different. Xiao Bian suggested that the search of the navigator by car is very good, and it is faster to use the LBS service of Android in the high-rise building.
