Active faults or tectonic lines are clear boundaries between a very active region and a quiet region . 活動斷層或構(gòu)造線是強烈活動已和平靜區(qū)之間的清晰邊界。
Volcano - tectonic line 火山構(gòu)造線
This system can accomplish effectively many functions through computer such as field terrane - surveying of geology catalog , drawing tectonic lines , building spatial model based on digital image , fast querying of terrane - attribute and figure database , cartography through cad technology and so on 此系統(tǒng)有效實現(xiàn)了在計算機上完成地質(zhì)編錄的外業(yè)產(chǎn)狀量測,構(gòu)造線素描,普通影像的空間建模,巖層產(chǎn)狀屬性、圖像數(shù)據(jù)庫快速查詢及cad成圖等等功能。
