With the rapid progress of information technology more and more people utilize high technology to boost the fast development of the national economy. Since the project of agricultural science and technology to farmer was put into practice by Ministry of Agriculture in 2005, 212 representative counties have been set, 200,000 typical households have been added, and 4 million peasants have enhance...

The focus of this editorial is on the potential of spatial thinking in teaching, both within spatially-enabled disciplines such as geography, environmental and earth science, and more broadly within the sciences and humanities. Although a persuasive argument has been made for the value of spatial thinking and GIS within a broader research context (e.g., Goodchild & Janelle, 2004 for the social ...

The relationship between critical geography and geoinformatics has recently entered a new phase of cordiality and constructive discourse, exemplified by the NCGIA Initiative 19 [27], the Varenius project [21] and a variety of journal special issues on the topic of GIS and society (eg [28]). This new-found entente has opened the way to the re-evaluation of existing GIS-based research and to much...

As government-insured populations grow, commercially insured populations decrease, and declining insurance reimbursements pressure cost and revenue. Health systems must strive to improve quality while lowering costs. Large medical centers with rural sites must understand their geography and how distances impede access to services, thereby affecting patient health. Without relevant data, which c...

Opportunities of potential human activities have extended from physical space to virtual space in today’s society. Based on a proposed conceptual framework that models the relationships between physical and virtual spaces, this paper presents an attempt to adjust the space-time prism concept of Hagerstrand’s time geography to identify potential activity opportunities in virtual space, focusing ...

In recent years GIS practitioners have begun to argue for the importance of building a more flexible, open, and theoretical science of geographic information systems and geographic information – a geographic information science (Goodchild 1992, 1993, 1995; Openshaw 1991, 1992, 1996; Wright et al 1997). This theoretical turn has emerged as GIS itself has changed from an enterprise involving the ...

This is the preprint version of our paper on ICWL2015. A virtual reality based enhanced technology for learning primary geography is proposed, which synthesizes several latest information technologies including virtual reality(VR), 3D geographical information system(GIS), 3D visualization and multimodal human-computerinteraction (HCI). The main functions of the proposed system are introduced, i...
