agriculture is a complex system science and the knowledge of it is consisting of much concepts and relationships. examinations in connection with site-specific farming have been carried out by our institute since 1998. precision farming is a way of agricultural production, which takes into account the in-field variability, a technology where the application-seeding, nutrient replacement, sprayi...

Recently, Web-based GIS applications have become important tools for disseminating geographical information in digital map format on the Internet because of their platform independence, interactivity, and wide accessibility. This trend brings about new insights on the integration of Web-based GIS and multimedia on the Internet since multimedia has already been seen as the strength of Internet a...

Cutting-edge tourism portals have to integrate GIS information. However, GIS data formats differ from usual tourism portal data formats. In this paper we propose a web application architecture which uses GIS as a main information resource and therefore diverges from standard web application architectures. GIS data as well as relational data is wrapped into XML and processed by an XSLT processor...

Increasing application of Geospatial information requires integration , fusion and interoperability of current monolithic GIS, especially more complex and multidisciplinary involved application. Interoperability is base for information integration and fusion. we give five-level GIS interoperability model(InteroModel5). The spatial information infrastructure(SII) provides a sharing spatial infor...

Recent researches on Three-dimensional Geographic Information System (3D GIS) modeling technology were reviewed. The concept of 3D GIS modeling and its application in various fields were introduced. Essential techniques to realize 3D visualization were studied. A typical 3D GIS modeling usually contains the description and the transmission of GIS spatial data structure. GIS spatial data models ...

The article expatiates the conception, definition and application status of GIS and IGIS and discusses the two systems to form agriculture application IGIS combined with three GIS development tools including Arcinfo , MapInfo and SuperMap.

Today, we hear more Mobile, and find some mobile GIS application in our everyday life, such as GPS car management However, what is mobile GIS? What is the difference among Static GIS and Temporal GIS? This seems to be the first step to study mobile. The paper, it gives the concept of mobile GIS, the system Architecture of Mobile GIS, the key research area in mobile.

Grid GIS is a new technology which integrates the Grid with GIS. The analysis and application of geospatial information based on WebGIS now has new contents and application approaches based on Grid GIS, so the assignment and realization of computation tasks are more complex. The algorithm Com-Pool which is applied in Grid GIS can realize the task scheduling for its simple and practical characte...
