| 1 | Crowdsourcing geographic information for disaster response:a research frontier显示文摘Geographic data and tools are essential in all aspects of emergency management:preparedness,response,recovery,and mitigation.Geographic information created by amateur citizens,often known as volunteered geographic information,has recently provided an interesting alternative to traditional authoritative information from mapping agencies and corporations,and several recent papers have provided the beginnings of a literature on the more fundamental issues raised by this new source.Data quality is a major concern,since volunteered information is asserted and carries none of the assurances that lead to trust in officially created data.During emergencies time is the essence,and the risks associated with volunteered information are often outweighed by the benefits of its use.An example is discussed using the four wildfires that impacted the Santa Barbara area in 20072009,and lessons are drawn. | Michael F.Goodchild JA.lan Glennon | 2010 | International Journal of Digital Earth2010，3，3： | 58 |
| 2 | Building geospatial infrastructure显示文摘Many visions for geospatial technology have been advanced over the past half century.Initially researchers saw the handling of geospatial data as the major problem to be overcome.The vision of geographic information systems arose as an early international consensus.Later visions included spatial data infrastructure,Digital Earth,and a nervous system for the planet.With accelerating advances in information technology,a new vision is needed that reflects today’s focus on open and multimodal access,sharing,engagement,the Web,Big Data,artificial intelligence,and data science.We elaborate on the concept of geospatial infrastructure,and argue that it is essential if geospatial technology is to contribute to the solution of problems facing humanity. | Jack Dangermond Michael F.Goodchild | 2020 | Geo-Spatial Information Science2020，23，1： | 2 |
