精准扶贫战略是新时期我国扶贫领域具有中国特色的脱贫攻坚的主要模式,在习近平总书记提出的“六个精准”指引下,整合政府相关部门扶贫数据资源,研究如何利用测绘地理信息和大数据技术,精准获取贫困信息,为精准脱贫提供基础支撑,意义重大。以贵州省自然资源“一张图”平台为基础,将地理国情普查高分卫星影像成果,相关扶贫专题数据与空间信息数据相结合,利用测绘地理信息、大数据技术,建设贵州省精准扶贫作战图管理系统,实现扶贫对象精准定位,扶贫工作精准管理,为年度扶贫工作成效考核提供重要依据。 相似文献

贫困问题一直是中国政府致力解决的社会问题,随着中国经济的发展,扶贫业绩显著,贫苦人口的分布也转变为"广而散,小而集中",呈现出碎片化分布的特点。针对"精准扶贫"政策实施过程中出现的贫困户精准识别、管理、帮扶、考核、预测等问题,提出了基于GIS的扶贫空间数据可视化、空间分析以及预测模型,对扶贫工作进行更好的规划、决策和预判。为此将GIS技术与"精准扶贫"政策进行了有机的契合,开发了基于GIS的精准扶贫管理平台,通过研究导致贫困的各种因素和障碍,初步对贫困的发展趋势进行预判,达到了可持续脱贫的目标。对贫困户建立的完善的帮扶追踪机制,扶贫监督管理方案,为"全民脱贫"目标奠定技术依托。使得扶贫工作的针对性更强,有效性得到改进,为后期扶贫攻坚打下良好基础。 相似文献

正精准扶贫工作是党和国家"十三五"期间最艰巨的一项工作,也是全面建成小康社会征程上必须完成的重要任务。西藏自治区,作为我国西部欠发达省份之一,如何在2020年实现全面小康,精准扶贫工作将起到关键性作用。面对占国土面积八分之一的雪域高原,西藏自治区测绘局党员、领导和干部职工都颇感焦虑,因为,这里还有44个深度贫困县、315个深度贫困乡镇、2440个深度贫困村,涉及建档立卡 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
