Research of Improved Shortest Path Algorithm in Campus GIS

In searching of campus geographic information system, the shortest path is always the key and its efficiency which determines the quality of the service of the digital campus directly. In the classic algorithm, the time complexity is proportional to the vertex number's square. With the increasing of the vertex number, the speed will fell down sharply. Based on the reality such as the large number of population, plenty of buildings, teaching resources, this article proposed an improved bi-directional A* algorithm which changing the target point into surface in search direction by using the middle list searching the target bi-directionally. The experimental results show that, compared with Dijkstra and A* algo- rithm, bi-directional A* algorithm is the fastest in the search, even when the vertex number large, it also can compute well.

Research on Application of Sensor Monitoring Technology Based on the IOT in the Campus GIS Pipeline System

Application of the IOT (Internet of Things) technology has promoted the “digital campus” developing into “smart campus”. This paper applies the sensor monitoring technology based on the IOT to the existing GIS underground pipeline management system, to achieve across species and a full range of real-time monitoring of the pipeline. Use sensors for collecting data, and RS485 communication bus and GPRS network for data transmission, and batch estimation data fusion method to optimize the monitoring data. It has practical significance to realize intelligent management of campus underground pipelines.

Scheme Design of Mobile Phone Campus GIS System Basing on the Windows Phone Platform

The rising of the cloud computing and the generation of GIS cloud will promote the development mode of server and client into a new high tide, and with the popularity of intelligent mobile phones and plate computer, mobile will not only the development trend but also the trend of the development of IT, and then the development of intelligent mobile phone for the mobile GIS development will be the future GIS development of one of the main trend. So in our study, we considered how to explore the future wisdom campus mobile end GIS product, from this view, so we choose the system which is today's popular Windows Phone operating , and basing on the the wisdom campus, and design mobile Phone campus GIS system.Our research and development process choose the Microsoft Visual Studio 2010 as development platform, we using c # language for development, and choose ArcGIS Server10 as GIS service server, design and develope the Windows Phone mobile Phone about the mobile Phone campus GIS system. The whole system mainly consists of campus news module, course arrangement module, map query module, my diary module, recent weather modules, the system will convenience users’ campus life, which is also a very meaningful exploration and attempt for the intelligent campus.

A ZigBee-based Building Energy and Environment Monitoring System Integrated with Campus GIS

In this paper, the design and development of a Building Energy and Environment Monitoring System (BEEMS) for smart campus applications is proposed. The system is implemented based on distributed sensor nodes using ZigBee technology, which empowers the collection and monitoring of various types of measurements that reflect the energy consumption and environmental status of buildings. These parameters include temperature, humidity, air velocity, sound, bubble globe temperature, TVOC, CO2 concentration, air quality level, et al. The application software system is developed using jQuery-based Ajax general interactive architecture, and further integrated with campus GIS, which offers rich analysis and report functions for monitoring both energy consumption and environment parameters.

The Design of Campus Geographic Information System Based on MapX5.0+VB6.0

Because the traditional campus GIS (CGIS) lacks close contact and unified management between the spatial data and attribute data, it can not meet the needs of information construction and management for campus. The author proposes the system construction goals of the “digital campus”, which bases on information and figures technology, after analyzing CGIS model, functions and features.VB6.0 is the developing tool and MapX the components of MapInfo is the developing platform. The campus information’s stratification method of spatial database, the table structure of attribute database and functions of system are designed by the author. And the functions of data input, output and update; display and maintenance maps; query the shortest path are all studied. They are all the useful exploration for establishing the CGIS.

Spatial Data Mining Based on Campus GIS

With the rapid development of spatial database technology, spatial databases have been widely used in many engineering fields and rapidly increase in data capacity. Thus, to mine useful information from large spatial databases turns into a difficult but important task. In this paper, we apply the traditional data mining into spatial database and give a mining model for spatial data based on Campus GIS. Moreover, based on campus GIS, we implement a spatial data mining prototype system that is able to discovery the useful spatial features and patterns in spatial databases. The application in the campus GIS of a university has shown the feasibility and validity of the system.

A Spatial Data Mining Prototype System

With the wide application of the spatial database in remote sensing, geography information system,medical image, etc, which also leads to a sharp increase in spatial data A large amount of knowledge is hidden in the spatial database In order to obtain useful information for us, we have to analyse these spatial data In this paper,we introduce the design and implemention of spatial data mining prototype system based on campus GIS. give the system architecture of campus GIS, integrate data mining system with campus GIS, set up a model of prototype system, give the chart of system flow process and programming implemente it. Successful application of the system on the campus GIS of a university has tested the feasibility of this system.
