| Abstract: | In order to improve traditional data-acquiring method which is based on toilsome manual survey and the data is not accurate enough to be used in precise analysis,the article introduces a method of stratum data-mining of field archaeology based on geographical information system(GIS) database.There are 11 sections in Jiangzhai Site,Lintong,Shanxi in China,which are instanced for testing the method.The pretreatment is a series of GIS progress including framing standard cultural stratums of Jiangzhai Site and demarcating the different stratums of the 11 sections,digitizing,transforming and building topology of the 11 sections,and then setting down the framework of the GIS database and evaluating the attributive result.After that,spatial data-mining is done,namely,with virtual bore scanning section stratum maps which have been digitized and transformed,to distill spatial data from the information of the intersection of virtual bore lines and section stratums(lines).The spatial data involve the width,top length and bottom length of stratum and relic,the top and bottom caliber of relic,which are necessary in field archaeology.The scanning interval could be altered and the less interval value,the more accurate the data.In addition,according to some simple arithmetic that data could be made new information to meet some other need in field archaeology analysis,even describing and visualizing the stratum.At the same time,the data of the same cultural stratum in different section could be added up to acquire more information of some larger region,predicting and evaluating the distribution of the relic.It is proved that not only kinds of stratum information can be gotten automatically through the method,but also the information is more believable and abundant than the original data in related documents. |
