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. |
