Net geographic spatial data processing based on svg technique 技術(shù)的網(wǎng)絡(luò)地理空間數(shù)據(jù)處理
The thesis begins with explanation of crm, and then explains its main constructing parts and each part's requires of spatial data processing 本論文從剖析crm入手,研究各部分對空間信息的需求,探討了空間型crm的基本組成,以及實(shí)現(xiàn)空間型crm的技術(shù)方法。
The quality controlling of spatial data and the format transforming of spatial data, which are the main components of the thesis, are the two important aspects of spatial data processing 空間數(shù)據(jù)處理是gis的重要功能。空間數(shù)據(jù)質(zhì)量控制和空間數(shù)據(jù)格式轉(zhuǎn)換是空間數(shù)據(jù)處理的主要內(nèi)容。
Combining the project of land utilization status management, the thesis analyzes and discusses spatial data processing about land utilization, and provides some practical scheme on designing and realizing ideas 本文從這兩個(gè)方面,結(jié)合土地利用現(xiàn)狀管理,對空間數(shù)據(jù)處理進(jìn)行了分析和探討,從設(shè)計(jì)思路和實(shí)現(xiàn)方法上提出了切實(shí)可行的解決方案。
Finally, some key technology and realizing means about spatial data processing is discussed . in the conclusion part of the thesis, some results are given as follows : ( 1 ) a practical system design of " land utilization alteration survey information system " is provided; ( 2 ) spatial data quality control is explored and realized by programming; ( 3 ) spatial topology relation is analyzed and researched, and some idea of the checking spatial topology relation is provided and realized; ( 4 ) the data transforming and exchange between maplnfo and cnsdtf is solved 最后本文得到了如下一些結(jié)果:(1)提出了一個(gè)實(shí)際可行的“土地利用變更調(diào)查信息系統(tǒng)”的系統(tǒng)分析設(shè)計(jì)方案;(2)對實(shí)現(xiàn)空間數(shù)據(jù)質(zhì)量控制進(jìn)行了探索和編程實(shí)現(xiàn);(3)對空間拓?fù)潢P(guān)系進(jìn)行了分析和研究,并提出了基本方案,實(shí)現(xiàn)了部分空間拓?fù)潢P(guān)系的檢查;(4)解決了mapinfo與cnsdtf之間的數(shù)據(jù)交換問題。
