随着地理信息科学(GIS)专业技术的飞速发展,该技术已经应用到社会各个方面,使人们的生产、生活发生了巨大变化,我国不少行业和研究领域开始应用GIS来解决科研、生产,以及经济与社会发展中的实际问题。面对当前社会多层次应用的需求,迫切需要一大批既掌握GIS技术,又懂管理,且能够将GIS技术深化应用的复合型人才。然而相对社会需求的新特点,我国高校GIS专业培养的毕业生面临诸多限制和不足,很难满足社会的需求。这就需要高校改革现有的GIS专业培养模式,从社会多层次需求出发,结合当前社会发展的客观实际,建立突出学校特色与学生能力的GIS专业人才培养模式。 相似文献

GIS专业实践教学综合改革研究 总被引:19,自引:0,他引:19
实践教学一般包括实验教学、课外实习、生产实习、专项设计和课外科技活动等多种模式。实践教学在全面提高学生素质,培养创新意识强、实践能力强的应用型和创新型高素质的复合型人才方面有着极其重要的作用。GIS专业的学科特点决定其实践教学具有理论教学更加不可取代的重要作用。据此,作者根据多年来所从事GIS专业教学工作的实践,结合GIS学科特点,对GIS专业实践教学的认识、实践教学内容、实践教学模式和实践考核方式中存在的问题进行了全面的分析,总结提出了一些具体的改革措施。 相似文献

Although it is well known that coseismic gravity changes take place during an earthquake, previous research has not yielded convincing evidence demonstrating that significant gravity changes occur before large earthquakes. Furthermore, even if we suspect that gravity changes occur before large earthquakes, we have yet to demonstrate how to consistently observe these changes for useful earthquake forecast that would bring benefits to society. We analyzed ground gravity survey data obtained in 1998, 2000, 200... 相似文献

The area around Sataun in the Sirmur district of Himachal Pradesh, India (falling between the rivers Giri and Tons; both tributaries of the Yamuna River) was studied for landslide vulnerability on behalf of the inhabitants. The study was made using extensive remote sensing data (satellite and airborne). It is well supported by field evidence, demographic and infrastructural details and aided by Geographic Information System (GIS) based techniques. Field observations testify that slope, aspect, geology, tectonic planes, drainage, and land use all influence landslides in the region. These parameters were taken into consideration using the statistical approach of landslide hazard zonation. Using the census data of 1991, vulnerability of the populace to the landslide hazard was accessed. As most of the infrastructure in the region is concentrated around population centres, population data alone was used for vulnerability studies. 相似文献

Abstract Virtual Australia is not a well-defined or agreed concept. This discussion paper conceptualises Virtual Australia as a ‘virtual [digital] model containing and representing all non-trivial objects and their contextual environment – from blue sky to bedrock – in real world Australia’. It describes a scenario for Virtual Australia, one or two decades from now, in which the locations and conditions of non-trivial objects and their environment are updated automatically through a combination of remote sensing and wireless communication technologies in support of a ‘Supranet’. It then examines the concept of the ‘Supranet’ – a pervasive information network based largely on wireless technology linking the physical world to a virtual model in real time – and develops and discusses three principal characteristics of the Supranet: the ability to have or collect specific information (know); the ability to process information (think); and the ability to communicate that information. If, in the near future, any or all non-trivial devices are to some extent able to know, think and communicate, the potential for object autonomy will be realised. 相似文献

Toward seamless indoor-outdoor applications: Developing stakeholder-oriented location-based services
Kohei OGAWA Edward VERBREE Sisi ZLATANOVA Naohiko KOHTAKE Yoshiaki OHKAMI 《地球空间信息科学学报》2011,14(2):109-118
Location-Based Services (LBS),an emerging new business based on smartphone and mobile networks,are becoming more and more popular.Most of these LBSs,however,only offer non-seamless indoor/outdoor applications and simple applications without giving stakeholders the chance to play an active role.Our specific aim is to solve these issues.This paper presents concepts to solve these issues by expanding the Open Location Services Interface Standard (OpenLS) to allow seamless indoor/outdoor positioning and to extend the content of the services to include information recommended by stakeholders. 相似文献
