【摘要】：地質(zhì)界線要素是地質(zhì)圖空間數(shù)據(jù)庫(kù)的基本要素之一。地質(zhì)界線圖層通常是地質(zhì)圖空間數(shù)據(jù)庫(kù)中圖元最多的一個(gè)圖層,其數(shù)字化和質(zhì)量檢驗(yàn)工作較為繁重。針對(duì)已有地質(zhì)體面圖層,而地質(zhì)界線圖層缺失的情況,本文提供一種快速補(bǔ)充地質(zhì)界線圖層的方法。該方法也可對(duì)原生地質(zhì)界線圖層進(jìn)行屬性數(shù)據(jù)的自動(dòng)化質(zhì)量檢驗(yàn)。其主要處理環(huán)節(jié)包括:首先,基于地質(zhì)體面圖層,構(gòu)建地質(zhì)體鄰接關(guān)系圖,可實(shí)現(xiàn)對(duì)地質(zhì)界線高效、準(zhǔn)確地提取;其次,基于產(chǎn)狀數(shù)據(jù)與斷層數(shù)據(jù),運(yùn)用地層接觸關(guān)系識(shí)別規(guī)則,可分別實(shí)現(xiàn)對(duì)基本地層接觸關(guān)系和斷層接觸關(guān)系的自動(dòng)識(shí)別;最后,針對(duì)兩鄰接地質(zhì)體面實(shí)體多段界線間的接觸關(guān)系識(shí)別結(jié)果不一致的情形,運(yùn)用"平行不整合優(yōu)先"原則和"長(zhǎng)度優(yōu)先"原則,進(jìn)行了合理的綜合判別。基于1:50 000廬山幅地質(zhì)界線圖層的自動(dòng)化生成實(shí)驗(yàn)表明,本文方法可高效、快捷、準(zhǔn)確地生成地質(zhì)界線圖層,既能夠滿足自動(dòng)化補(bǔ)充地質(zhì)界線圖層的需要,又可作為檢驗(yàn)地質(zhì)界線圖層屬性的有效工具。
[Abstract]:Geological boundary factor is one of the basic elements of geological map spatial database. The geological boundary layer is usually a layer with the most elements in the geological map spatial database, and its digitization and quality inspection work is more arduous. In view of the absence of geological boundary map layer, a method to quickly supplement geological boundary map layer is provided in this paper. This method can also be used to automatically check the quality of the attribute data of the primary geological boundary layer. The main processing steps are as follows: firstly, based on the geological decent layer, the adjacent relation map of geological body can be constructed, which can efficiently and accurately extract the geological boundary; Secondly, based on the occurrence data and fault data, the recognition rules of stratum contact relation can be used to realize the automatic recognition of the basic formation contact relationship and fault contact relationship respectively. Finally, in view of the inconsistent identification results of the contact relationship between the two adjacent geological decent entities, the principles of "parallel unconformity first" and "length first" are used to make a reasonable comprehensive judgment. Based on the automatic generation experiment of the geological boundary layer of the 1:50 Lushan block, it is shown that the method in this paper can generate the geological boundary layer efficiently, quickly and accurately, which can meet the needs of the automatic supplement of the geological boundary map layer. It can also be used as an effective tool for checking the attributes of geological boundary layers.
