数据可视化及其在地学中的应用

数据可视化是将多维数据以图形、图像方式显示,拓宽了传统图标的功能,提高了人们对数据的处理及解释能力,为更好地利用数据奠定了基础。数据可视化已经应用于处理地学数据,并且应用各种语言开发出了多种数据可视化技术。本文简要地介绍了数据可视化及其在地学中的应用,并结合实例介绍了其实现语言OpenGL、实现技术分治技术。指出开发四维及四维以上图形显示技术是可视化研究的难点。

DATA VISUALIZATION AND ITS APPLICATION IN GEOSCIENCE

Data visualization displays multi-dimensional data with figures or images,which not only widens the functions of traditional icons,but also improves people's ability of processing and interpreting data.Data visualization has already applied in geosciences data processing,and scientists had also developed several data visualization techniques with different languages.In this article,we introduce data visualization and its application in geosciences,then show the OpenGL language,divide and conquer technique.Finally we point out that developing techniques which can display more than four dimensions are very difficult.
