Based on knowledge and rules,this paper brings forward a new quality inspection method for cadastral data quality.

After a deep research into the related theories in the field of knowledge engineering and GIS knowledge and rule system, this paper is to present a new approach to data classification and the general frame and mining principle of spatial data knowledge and rule system, providing a complete plan to systematically solve the problem of spatial data sharing among different professions and standards.

The form and mechanism of inference of information understanding,semanteme structure of rule knowledge and production process of new knowledge is discussed ;the memory matrix、computation rule of semanteme truth value and confidence factor of recognition reasoning are established.

Learning algorithm model of constructive PONN based on knowledge rules;

After analyzing the defect and shortcoming of current pipeline check software,the domain-driven design method and UML are introduced to review the check rules,then the pipeline check knowledge rule base capable of customization and its reasoning engine are put forward,finally checking the all-sided investigation pipeline data and its vector data combining with GIS intelligently is realized.

Aim at the workflows as be modeled with knowledge rules,how to keep the reliability of the user defined knowledge rules,workflow model,simulation platform building and simulation engine are studied in this paper,find out the bugs by using visual instance display and statistic technic.

This paper mainly introduced realizing the regular knowledges of″expert system of dam safety monitoring″with VC++for Windows.

RS information extraction techniques of Pinus massoniana forests based on knowledge rules;

Taking Beibei urban region as study area,and based on knowledge rules combining spectral feature,Gray Level Co-occurrence Matrices texture feature and shape feature,a classification method is presented in this paper.

Therefore it is necessary to establish knowledge rules for generalization of a certain special purpose map one by one,which can accelerate the systematization and standardization of special purpose map and.
