On this condition , the paper gives the detailed design and implementation of an editor for courseware description language ; moreover , gives some important data structures and algorithms used during development . some of the methods are very practical 在此基礎(chǔ)上,本文討論了一個具體的針對課件描述語言的編輯器的設(shè)計開發(fā)以及實現(xiàn)過程,并對開發(fā)過程中重要的數(shù)據(jù)結(jié)構(gòu)以及算法進(jìn)行了描述。
Chapter 1 introduces some fundamental conception , development of ecdis and the meaning of researching , gives a synoptic scheme of the plat . chapter 2 discusses the organization and management architecture of chart data , give the detailed data structure and algorithm to operate 第二章研究了海圖數(shù)據(jù)的組織和管理體系,并給出了支持s - 57和s - 52的數(shù)據(jù)結(jié)構(gòu),以及相應(yīng)的數(shù)據(jù)操作算法和坐標(biāo)投影解算算法。
3 ) discuss the multi - scale representation of multiple scale data set with huge capacity , analyze the data structure and algorithm of representation of multiple scale data set with huge capacity , use the quad - tree structure realizing the no - boundary ramble and different scale data auto switch 實踐證明,本文所采用的方法具有一定的實用性,效果良好。 3 )探討了多比例尺海量數(shù)據(jù)的多尺度表達(dá)問題,研究了多比例尺海量數(shù)據(jù)多尺度表達(dá)的數(shù)據(jù)結(jié)構(gòu)和算法。
