Spatial Data Infrastructure in India: Status, Governance Challenges, and Strategies for Effective Functioning
The paper describes the status of national spatial data infrastructure (NSDI), the spatial data infrastructure (SDI) of India in terms of its vision, data formats, metadata, various standards (metadata standard, exchange standard, and application protocol), network framework, macropolicies, datapricing and dissemination policies, copyrights, and clearinghouse issues. It identifies the challenge...
متن کاملارزیابی زیرساخت اطلاعات مکانی ملی ایران بر اساس مدل آمادگیSDI
هدف اصلی این پژوهش تعیین شاخص آمادگی زیرساخت اطلاعات مکانی ملی (NSDI) ایران و شناسائی عوامل محدودکننده در ایجاد این زیرساخت می‌باشد. چارچوب اصلی پژوهش بر اساس پیمایش و مدل آمادگی زیرساخت اطلاعات مکانی (Readiness ModelSDI) بنا شده است. در این تحقیق، NSDI ایران بر اساس این مدل فازی پایه، با استفاده از 16 معیار تصمیم‌گیری در قالب پنچ عامل سازمانی، منابع انسانی، داده و اطلاعات، فناوری و مالی مورد ا...
متن کاملDefining National Spatial Data Infrastructures as Complex Adaptive Systems
After two decades of intensive worldwide development of (National) Spatial Data Infrastructure (NSDI) initiatives it is increasingly important to assess the outcomes in order to justify the resources spent on those programs. Many researchers throughout the world have been struggling with building NSDI assessment programs. However it is very difficult to assess NSDIs due to its complex, dynamic ...
متن کاملCreation of an NSDI strategy - Case Study Croatia
This paper gives an overview of research conducted in Croatia to recognize the needs and expectations of spatial data producers and users at national level in the process of improvement of the existing NSDI. The results of the research make groundwork for creating an NSDI vision and an efficient national improvement strategy. For building such a strategy, a general model of improvement was devi...
متن کاملStrong-field nonsequential double ionization of Ar and Ne
We investigate the nonsequential double ionization (NSDI) of Ar and Ne based on quantitative rescattering theory (QRS). According to QRS theory, each elementary NSDI process can be calculated by multiplying the returning electron wave packet with appropriate differential electron-ion scattering cross sections. We include (e, 2e) and electron-impact excitation cross sections of Ar+ to obtain the...
