地理信息服务的思考与探索

GIS正在从传统意义上的地理信息系统向地理信息服务发生偏转,地理信息服务已成为信息服务业中的一个重要组成部分。文中归纳总结了地理信息服务概念、技术体系、服务模式以及我国地理信息服务发展的差距、对策与建议。     

三维城市模型的研究与实践(英文)

The way we interact with spatial data has been changed from 2D map to 3D Virtual Geographic Environment (VGE). Three-dimensional representations of geographic information on a computer are known as VGE, and in particular 3D city models provide an efficient way to integrate massive, heterogenous geospatial information and georeferenced information in urban areas. 3D city modeling (3DCM) is an active research and practice topic in distinct application areas. This paper introduces different modeling paradigms employed in 3D GIS, virtual environment, and AEC/FM. Up-to-date 3DCM technologies are evolving into a data integration and collaborative approach to represent the full spatial coverage of a city, to model both aboveground and underground, outdoor and indoor environments including man-made objects and natural features with 3D geometry, appearance, topology and semantics.

山区遥感图像自动分类研究——以西南地区为例(英文)

In mountainous areas, it is the undulant terrain, various types of geomorphic and land use that make the remote sensing images great metamorphism. Moreover, due to the elevation, there are many areas covered with shadow, clouds and snow that make the images more inaccurate. As a result, it would be very difficult to carry out auto-classification of RS images in these areas. The study took Southwest China as the case study area and the TM images, SPOT images as the basic information sources assisted by the a...     

科学找矿是实现新突破的重要保障

矿产是人类社会赖以生存和发展的重要自然资源。随着社会生产力的提高和社会进步,人类使用矿产的种类和数量在急剧增长。据统计,近半个世纪以来,全球的矿产开采量已超过人类几千年历史中开采矿产量的总和,利用矿产种类已达160种以上（包括能源、金属和非金属矿产等）。随着全球人口的增长和人民生活水平的提高,将需要更多品种和更大数量的矿产资源作支撑。因此,树立科学找矿意识,加强基础地质研究,拓展地学功能,已成为实现找矿新突破和地质勘查可持续发展的关键。

The effect of the wave-induced mixing on the upper ocean temperature in a climate model

The significant underestimation of sea surface temperature （SST） and the temperature in the upper ocean is one of common problems in present climate models. The influence of the wave-induced mixing on SST and the temperature in the upper ocean was examined based on a global climate model. The results from the model coupled with wave-induced mixing showed a significant improvement in the simulation of SST and the temperature in the upper ocean compared with those of the original model without wave effects. Although there has still a cold bias, the new simulation is much closer to the climatology, especially in the northern ocean and tropical ocean. This study indicates that some important physical processes in the accurate simulation of the ocean may be ignored in present climate models, and the wave-induced mixing is one of those factors. Thus, the wave-induced mixing （ or the effect of surface waves） should be incorporated properly into climate models in order to simulate or forecast the ocean, then climate system, more accurately.
