80年代,加拿大测绘学会(CISM)的业务活动和研究领域发生了一些深刻的变化,这些变化不仅影响到业务活动的科学、技术内容,甚至涉及到专业方向。因此,使CISM不得不重新考虑其活动领域,确定活动领域的目标以及重新评估自身在多学科范围内... 80年代,加拿大测绘学会(CISM)的业务活动和研究领域发生了一些深刻的变化,这些变化不仅影响到业务活动的科学、技术内容,甚至涉及到专业方向。因此,使CISM不得不重新考虑其活动领域,确定活动领域的目标以及重新评估自身在多学科范围内的作用。此时,Geomaties(地学信息工程学)一词逐渐进入CISM的活动领域,并且从1990年开始酝酿将CISM改名为ACSG(法文名,加拿大地学信息科学协会)。 展开更多

The authors compare key elements of the emerging field of Indoor Location-Based Services(Indoor LBS)to those currently found in spatial data infrastructure(SDI)programs.After a brief review of SDIs and Location-Based Services,the corresponding drivers,characteristics and emerging issues within the field of Indoor LBS are introduced and discussed.A comparative framework relates the two in terms of the criteria‘People’,‘Data’,‘Technologies’,‘Standards’and‘Policies/Institutional Arrangements’.After highlighting key similarities and differences,the authors suggested three areas–definition of common framework datasets in Indoor LBS,more effective use of volunteered geographic information by SDI programs and development of appropriate privacy policies by both communities–that may benefit from sharing‘lessons learned’. 展开更多
