| 摘 要： | 国内城市地理数据开发和应用水平差异很大,且不少城市面临诸多困难和挑战。本文使用问卷调查和案例分析的方法评估城市地理数据的开发和应用水平,为城市地理数据资源开发和持续利用提供战略建议。同时分析了地理空间数据的基本特征,强调了地理数据的重要性,提出反映地理空间数据生产与应用水平的关键指标,如专业人才与组织、数据投资与预算、数据生产与供应、数据标准与质量、空间数据基础设施、数据法令与政策、数据应用与效益、数据共享程度、成功应用数目等,建议依据这些基本要素构建评估指标体系。最后提出了城市地理空间数据生产与应用调查的组织、方法和程序,并建议政府主管部门或行业协会尽快展开有关工作。

| Abstract: | Based on the fact that the urban and regional geographic information development is quite uneven in China, this paper introduces an idea to measure the levels of geographic information development in urban areas using methods of questionnaire survey and case study. The authors discuss the natures and characteristics of geographic information from multiple perspectives, and present several development indicators such as professional and related organization, data investment and budget, data production and supply, data quality and standard, information infrastructure, related law, policy and regulation, application and benefit, and degree of data sharing. The related development degree index, questionnaire design, and case study design should consider these indicators carefully according to the research purpose. Finally, it is suggested that the government administrators and / or professional organizations should conduct a nationwide evaluation of urban geographic information development and formulate general strategies for China's long-term urban geographic information development and application. |
