【摘要】 本文以"地学空间信息检索系统"为例,通过不同应用实例分别对地质资料中矢量数据和栅格数据的发布机理进行综合分析研究,以及投影参数统一化、栅格影像数据的静态切片(四叉树切片原理)、图块拼合与编码格式转换等关键技术的引用,解决栅格数据海量效应的同时实现了地质资料大数据的发布、快速缩放浏览、属性解析与空间百度,归纳出了针对不同数据源采取不同方法的特点与优势,提供了极具操作性的技术流程,为后期应用提出了可供参考使用的合理化建议。更多还原

【Abstract】 This article,giving an example of ’Geological Dimensional Information Searching System’,uses different living examples to synthetically analyze the releasing mechanism of vector data and grid data in geologic information.Meanwhile,this article refers to several essential techniques such as unifying projection parameters,static slicing of grid image data(principle quad tree section),segment cohering and code format conversing etc.to not only solve the effect of vast grid data,but also achieve publishing the big data of geologic information,exploring with quick zooming,property analyzing and dimensional searching.Consequently,this article concludes the advantages of using various methods focusing on different data sources.In addition,in order to throw out reasonable suggestions,which can be referred,for incoming applying,extremely exercisable technique process is provided.更多还原
