Abstract: The drillhole histogram drawn by traditional method are usually limited to specific software platform,such as AutoCAD,and are difficult to achieve cross-platform and network application.In this paper,through the design of general drillhole data model and the design and implementation of algorithm on filling drillhole histogram with the lithology pattern,the drillhole histogram data set including vector graphics and graphic description attribute is created.The data set is stored by standard data exchange format which is independent of programing language and software,can be applied to a variety of application platform,such as local desktop applications,PC internet and mobile internet,can achieve the "write once,run anywhere" goal of cross platform application.This paper takes a pratical project as an example to introduce these contents.
