摘要
随着地震勘探技术和测量技术的发展以及资料的积累,目前保存了大量的图形资料供使用,还有更多的图形需要整理和生成,但是不同图形格式之间不兼容,在使用时需要进行格式转换。本文对"AutoCAD的图形格式"、"ESRI的Shap图形格式"以及"MapInfo的图形格式"进行了介绍,对其结构、代码以及不同图形元素的表示方法进行了详细论述,对这些图形中加载栅格图所需要的参数及计算模型进行了说明,分析了不同图形之间相互转换的可行性,并提出了实现思路。
Along with development of seismic prospecting technology and survey technique as well as accumulation of data,a great deal of currently stored graphic data can be provided for usage,and more graphic data need to be processed and generated,but different graphic formats do not be compatible each other,which needs format conversion in usage.The paper introduced the AutoCAD,ESRI Shap and MapInfo graphic formats,expounded in detail the structure,code and represented method of different graphic elements,showed the parameters needed to loaded grid chart and computational model in these graphs,analyzed the feasibility that the different graphs can be converted each other and presented implement ideas.
