设施空间选址中的GIS技术支持 总被引:11,自引:1,他引:10
设施空间位置选择的好坏,直接关系到设施能否最大限度地发挥其效用和实现其利益或价值,而传统的选址决策方法存在着许多固有的不足。GIS技术的发展,为我们快速全面获取并交互可视化地分析建筑物所在区位的信息提供了良好的技术支持,从而为解决传统选址方法所面临的难题提供了新思路。本文详细介绍了GIS技术在设施空间选址中的支持作用。 相似文献

基于GIS与遥感影像的银行ATM机网点选址方法研究 总被引:1,自引:0,他引:1
本文针对当前影响ATM机布点的因素,提出了基于矢量图和遥感影像的可视化平台。首先应用门槛分析模型将区域划分为潜力区域(含有ATM机但还有布放潜力的区域)和空白区域(不含ATM机的区域),从宏观上分析区域布放的可行性,并通过计算潜力区域和空白区域内的网点消费潜力,得出适合布放ATM机的区域,然后通过点位评估模型来分析这些区域内的网点,最后评估出可以布放ATM机的网点,并以北京某公司ATM机布点选址规划应用本文的选址方法进行了实践,取得了很好的效果。 相似文献

公共停车场对于城市的建设与发展有着重要意义,兰州市在社会经济快速发展遇到的一系列问题中,停车难是较为突出的一个。本文以兰州市主城区为例,运用层次分析法实现了对公共停车场选址影响因子的客观选取以及权重的赋值,运用GIS可视化和空间分析功能,分别求得各因素的影响范围并按权值叠加,最终得到兰州市主城区公共停车场选址示意图。通过验证分析,该方法合理有效,不仅为兰州市公共停车场选址提供了科学依据,也为其他地区和其他设施的选址提供了参考。 相似文献

针对当前老龄化社会所带来的养老设施供给不足与供给不均衡问题,以滨城区为研究区,以精细化人口数据、养老设施数据为基础,分析格网单元的老龄化程度和养老服务压力,以POI数据与随机森林算法分别对主城区和乡镇区域构建选址模型,并进行空间选址预测;顾及老龄化程度和养老服务压力对选址结果进行等级划分。结果表明,主城区选址模型的正确率为89.83%,乡镇的选址模型正确率为90.72%;主导主城区和乡镇选址的指标不同,老年人口是影响主城区选址的主要因素,基础设施是影响乡镇选址的主要因素。在初步预测结果的基础上,将选址结果划分为一级需求适宜区、二级需求适宜区,为养老服务设施选址决策提供科学依据。 相似文献

A municipal solid waste (MSW) management system needs solid waste management (SWM) techniques where the presence of a sanitary landfill is vital. One of the most important issues of sanitary landfilling is to locate the facility to an optimal location. Despite the versatility and case-dependent nature of conventional expert-based site selection procedures, the number of sites to be chosen increases with increased population forcing a number of constraints. Consequently, constraints and environmental regulations mechanically mask unsuitable areas, leaving very little areas to be assessed. This turns the situation into a challenging issue for a geographical information system (GIS) used with multi-criteria decision analysis (MCDA), to select optimal site. The study aims to apply MCDA integrated with GIS to select possible sites of a MSW landfill with the same expert and same cognitive parameters while compared with the already present one. Results of this study revealed that conventional expert-based methods could not always evaluate all constraints at the same time and map reproduction is limited when parameter maps are changing rapidly in time. In order to produce cognitive and reproducible analyses, GIS with MCDA integration offers a good solution for site selection issue and forms a good alternative for conventional methods. 相似文献

3D geographic information system software’s (GIS) are widely used in engineering geology applications. This study was performed in the Karsiyaka settlement area for the preparation of engineering geological maps and evaluation of geological structures. Firstly, topographic maps digitized with Arcview GIS 3.2. Engineering geological maps were prepared using site works and digitized with the Rockworks 2006 programme and later stored in GIS-based computer systems. 3D modelling analysis and assessment using a geotechnical database is important to assist decision-making for land use and metro subway line planning, construction site selection, selection of water sources, etc. In this respect, the sub-surface of the study area is fully 3D visualized and useful soil class zonation maps for different depths maps are performed to be used in further studies. At last, after research at this site, the construction applications of Karsiyaka have multiplied. 相似文献

One of the prime global issues in the field of hydrological science is water scarcity and its degrading quality. In this paper, geographic information system (GIS) and remote sensing techniques are applied over a study of granite watershed area of ~200 km2 with semi-arid climatic conditions for estimating surface runoff using a modified soil conservation service curve number method and subsequent site selection for water harvesting structures such as check dams and percolation ponds to enhance recharge of groundwater. Further, some of the sites selected for appropriate construction of recharge structures through analytic hierarchy process were investigated for site efficacy. All the recharge sites selected were found feasible and appropriately suitable. This study demonstrates the capability of GIS and its application for the construction of water harvesting structures over semi-arid areas. 相似文献
