3维GIS技术在建设方案规划审查中的应用研究——以重庆某项目4号地块为例

将3维GIS引入到建设方案的分析与审查过程中,通过建立真实的3维场景,将建设方案纳入到3维场景中,借助GIS的空间分析工具,从不同的角度和视点对建设方案进行了分析,模拟了不同建设方案建成后对周围景观的影响,从而有力地支撑了方案的审查。

GGR Biennial Review: Reference Materials in Geoanalytical and Environmental Research – Review for 2008 and 2009

This review gives an overview of the literature on reference materials of geochemical and environmental interest for the two-year period 2008–2009. Reference materials play an increasingly important role in all fields of geoanalytical research. This is demonstrated by the large number of publications containing data on reference materials. Although many reference materials exist, there is still a great need for certified samples, so-called delta zero materials for stable isotopic work and homogeneous microanalytical reference materials. This review focuses on six topics: developments of certification processes of reference materials mainly postulated in ISO guidelines and the IAG protocol, new developments of the GeoReM database, investigations of powdered rock reference materials, Chinese reference materials published in Chinese journals, microanalytical reference materials and isotopic reference materials.
