This paper mainly introduces the implementation of Real-time field survey using Android-based interface of mobile GIS network. Real-time field survey and ground truth was made readily available for GIS researchers back in an office while a survey team was reporting from the field via a mobile network. Both geographic data and geo- referenced remotely sensed image data are served from this site. An...
With the continuous development of mobile communication technology, wireless internet technology and mobile terminal technology, geographic space information have already widely applied to various fields in our daily life. The traditional Geographic Information System (GIS) is developing to the mobile terminal, the popularity of Android embedded system provide a excellent platform for the development...
The increasing power and decreasing size of mobile devices and tablets provide a compelling new platform for mobile field geographic information system (GIS) operations with geospatial datasets. As these data sets become increasingly larger and more dynamic, it introduces the need for real time analysis and data collection in the field. Successful field research in the digital age requires computing...
A lot of work has been devoted to collaboration among distributed computing devices. Sensor networks and crowdsourcing are prominent examples of distributed collaborative computing. Much less attention has been paid to competition among computing agents, particularly the type that we call spatio-temporal competition. In it mobile agents compete for point resources located in space. An example of such...
Huge information is inherently associated with certain places in the globe. The ancient cities have multiple locations with large historical, geographical, cultural and architectural specialties. E-Learning systems allow the learners to learn irrespective of their time and place. The location based learning (LBL) is another aspect where the site seeing, and touching the building walls are the means...
SNS (social network service) is becoming more and more popular on the web, and it is even more so for Mobile Internet browsing. The huge success of foursquare on the web shows that introducing LBS (location based service) to mobile Internet is promising. With LBS, mobile device (client) needs to commit user's location information as a request to the remote server (server). The server receives the...
Geospatial technologies in conjunction with wireless grids will offer a context for locating and coordinating team activities in such a way that the nature of each team member's effort may be known and understood by other members. This constructed group knowledge enables teams to respond to unforeseen and emergent contingencies and act in concert through the active interpretation of shared artifacts...
An increasing number of new geolocation services are exploiting the new capabilities of smartphones, most of which incorporate GPS location. There are fewer applications for providing indoor location, partly due to the cost of the required infrastructure. In this paper, we present QR-Maps, a simple and efficient tool that can be used in smartphones to obtain accurate indoor user locations. This tool...
Location based service (LBS) is applied to mobile industrial and commercial administration GIS (MICA-GIS) in this paper. Firstly, the architecture of MICA-GIS is proposed and its main components are discussed. Moreover, two key technologies, grid based administration and mobile terminal of MICA-GIS, are analyzed. Finally, a conclusion is given.
The rapid development of wireless technology, the extensive use of mobile phones and the availability of location information are facilitating personalized location-based applications. Easy to carry, easy to use and easy to buy, smart phones with certain software are of great advantage. Consequently, mobile social networking (MSN) systems have emerged rapidly, being a revolution for our everyday life...
One main objective of this paper is to propose novel mechanisms to support low latency handover at authentication level using network selection, security context management and mobility and handover management in future telecom ecosystem to allow ubiquitous access to the Internet and services to any individual on the move. This access should be possible anytime anywhere while ensuring the right level...
The purpose of this paper is to combine the embedded GIS technology with GPS and PDA to develop a mobile line-inspection system,which can be used to inspect the lines for electric power transmission, mobile communications, petroleum and natural gas transmission,etc.The system can facilitate inspectors'work,improve inspection work more efficiency,and guarantee inspectors to examine on site.So it overcomes...
With the development of GPS and mobile network communication technology, it has been becoming possible for mobile phone users to acquire the geographical information anytime and anywhere. Based on Google Maps API technology, this paper proposes a novel solution of mobile digital maps system that realizes some functions such as electronic map browse and query, bus lines search, the rapid location positioning...
We present an effective solution for both digital map generation and real time user tracking for teams operating in hazardous environments or unfamiliar territory. The system is based on the client server model, where the client is a GPS enabled mobile phone which is capable of capturing coordinates and serving dynamic maps to the user. The maps plot the team's navigational routes and enables real...
Mobile applications are increasingly taking advantages of the diverse geospatial web services to meet the information needs of their users. However, matching available web services to user's information needs is not a trivial task, as there are many contextual factors that may influence the fitness of use. In addition, mobile activities can be highly dynamic and interleaving, which demand certain...
Summary form only given. The recent advances and price reduction of technologies for collecting spatial and spatio-temporal data like Satellite Images, Cellular Phones, Sensor Networks, and GPS devices has facilitated the collection of data referenced in space and time. These huge collections of data often hide interesting information which conventional systems and classical data mining techniques...
Nowdays, most people have embedded GIS devices, such as navigator, handset map and so on. But when developing embedded GIS software, programmers have to write different codes according to different embedded software and hardware. This paper explains the design and realization of Embedded GIS Graphic Mid-ware( CG-GDI). The Embedded GIS based on CG-GDI can be easily transplanted to other embedded software...
A new method of real-time downloading and distributed computing model is studied based on mobile geographic information system (GIS) environment. Key technologies are presented in the model, including mobile agent (MA) mobile computing, mobile GIS, global positioning system (GPS), least path computing model, and spatial information distributed grid computing and management model. In order to deal...
This paper discusses how to apply the GIS/GPS technology to the common mobile Logistics business to meet the requirements of efficient Logistics management. In the full analysis of GIS (Geographic Information System) and GPS (Global Positioning System) technology superiority in Logistics, this paper focuses on the system design issues and principles, and puts forward a GIS/GPS based solution apply...
In the process of land and resources informatization, it will cause massive spatial data acquisition, processing, transmission, distribution and application. But, as an important channel of distributing spatial data, the cable and wireless communication network can't match the growth rate of spatial data for the reason of its limited bandwidth. So, this is a huge contradictions, and thus forms the...
