Electric seal is a method to sign a document and it is a kind of electric signature, though a document has some difference compare to other kind of data like program, data of a database, according the speciality of a electric signature to a document, such as view what we signed , validate the signature in a document directly, how to archives a document which has been signed, how to read a document has been archived, it points out that a document is exactly some data with some format data, a document could be disparted as two parts, data and format data.

电子印章是应用层的数字签名，是电子签章的一种，由于文档签名与其他类型数据如程序，数据库数据等相比有其特殊性，本文针对文档签名的特殊性，如签名的可见与可证实性，文档的归档特性，文档阅读的方便性等进行了分析，指出文档实际上是一种格式化的数据，可以分为数据与格式两个部分，在此基础上提出了对文档进行签名的要求。

Within the integreted system,the function of the data-basedmanagement sub-system is to input,store,inquire and calculatedata;the function of graphic data management sub-system is toinput,store,inquire,display,output and transform data;thefunction of digital terrain model sub-system is to displaythree dimention graph,calculate slope,aspect and hilling;thefunction of general analysis model sub-system is to make multi-factor statistical analysis such as regression analysis;thefunction of applied model sub-system is to predict the amountof soil erosion,evaluate the land resource and make land useplanning.

The core part of this system development is to turndrawing datum, namely space data, into digital atlas in "ArcView", and then sort thedrawing datum into Point, Line, Polygon theme which user required so that we couldedit and manage these themes. The development process of this system is open. Users can edit and appendinformation at any moment if they want.

ArcView 的突出特色是能够将空间数据和属性数据动态结合在一起，开发过程中核心部分就是将所需的矿上图纸资料作为空间数据导入 ArcView 中形成数字地图并将其分为所需的点、线、面进行编辑管理，然后收集整理与空间数据中各主题相对应的属性表所需的属性信息并进行相应的编辑。
