【摘要】:結(jié)合地震應(yīng)急中對專題圖產(chǎn)出的要求,研究"天地圖-陜西"的切片方式和服務(wù)方式,在Arc GIS中實現(xiàn)了天地圖瓦片數(shù)據(jù)與矢量數(shù)據(jù)相結(jié)合。通過研究數(shù)據(jù)庫監(jiān)聽技術(shù)、基于Python語言和Arc Py包的出圖技術(shù),實現(xiàn)地震三要素的自動獲取和影響場產(chǎn)出,并最終實現(xiàn)了基于天地圖數(shù)據(jù)的地震專題圖自動產(chǎn)出,完全無需人工操作,提高了專題圖出圖效率。
[Abstract]:According to the demand of special topic map output in earthquake emergency response, the slicing mode and service mode of "Tianming-Shaanxi" are studied, and the combination of tip-tile data and vector data is realized in Arc GIS. Through the research of database monitoring technology, based on Python language and Arc Py package mapping technology, the automatic acquisition of seismic three elements and the impact field output are realized. Finally, the automatic output of seismic thematic map based on sky map data is realized. No manual operation is required, and the efficiency of thematic mapping is improved.
