Research On Comprehensive Log Diagram Based On Object Oriented Theory

Comprehensive log diagram is a very important part of geological maps, also isan important work of geological work, it carries on the comprehensive analysisaccording to the geological data on a region or drilling data and so on,draw attributeinformation of comprehensive log diagram object on the map, to make acomprehensive expression. Comprehensive log diagram object can be a stratigraphicunit, then the attribute information mainly includes erathem, system, series, group,formation, member, annotation, thickness, diagram, lithologic description, etc;comprehensive log diagram object can be intrusive rock, then the attributeinformation mainly includes age, super unit name, super unit annotation, unit name,unit symbols, lithologic pattern, lithologic description, genetic type and otherinformation; Comprehensive log diagram object can also be conglomerate inengineering drilling or oil gas in the oil drilling, etc.,it can extend out differentcomprehensive log diagram object, according to the different industry ofcomprehensive log diagram application or data.Comprehensive log diagram increases the readability of the map or data, makesusers can more quickly and intuitive interpretation of the histogram object attributeinformation. In this paper,we analysis of some problems in the aspect of functionusing the current mapping software to draw comprehensive log diagram, namely"more human interaction, low work efficiency and low drawing accuracy, and breakaway from the spatial data", Aiming at these problems, this paper puts forward theidea of comprehensive log diagram automation, and based on. Net developmentplatform and object-oriented design ideas, using C#programming language and theArcGIS Engine component library,we developed a comprehensive log diagramautomatic drawing module.There are two points to implement comprehensive log diagram automaticdrawing module. one is according to the object-oriented theory foundation, carries onthe class diagram design of comprehensive log diagram module, abstracting andinstancing the object of comprehensive log diagram, abstracting common point of various diagram objects, instantiating different diagram objects, in order to meet theneeds of different industries. Second is based on the database, storing comprehensivelog diagram data source, the form of comprehensive log diagram and the style of thetext information in the database in a certain way, builting the corresponding relationof comprehensive log diagram and its spatial data, and saving comprehensive logdiagram to the database, so that we can recover it conveniently.
