摘要
对应用较为广泛的Shape数据模型进行分析和研究,并且针对一幅全要素海图由于数据量大的原因导致读取和图形显示速度慢的问题,在实践中采用快速读取内存的方法,实现了数字海图的快速读取及显示,并且同以往循环读取方法进行了比较。
In this paper, SHP data model applied rather abroad is analyzed and studied, and aiming at the problems of the slower reading and displaying speed which result from numerous data of the chart, reading and displaying of charts is carried out quick by memory speedy reading in practice, and compared with the repeating reading methods.
