摘要：Along with the forthcoming of Google Earth, Virtual Earth, the next generation of Internet, Web 2.0, Grid Computing and smart sensor web, comes the new era for Geo-Information. In this paper, main features of new Geo-Information era are discussed. This new era is characterized by these fea- tures: serviced users are extended from professionals to all public users, the users are data and in- formation providers as well, provided geospatial data are no longer measurement-by-specification but measurement-on-demand through smart sensor web, and services are transferred from data- driving to application-driving. Such problems as out-of-order issues in geographic data collection and information proliferation, quality issues in geographic information updating, security issues in geographic information services, privacy issues in sharing geographic information and property is- sues on sharing geographic information, which are brought about by new geo-information era, es- pecially problems and challenges confronted in geo-information science and geo-spatial informa- tion industry, are analyzed. Then strategies concerning standards, planning, laws, technology and applications are proposed
