In land-use data generalization, the removal of insignificant parcel with small size is the most frequently used operator. Traditionally for the generalization
The back propagation (BP) model of artificial neural networks (ANN) has many good qualities comparing with ordinary methods in land suitability evaluation.Throu
In this paper,the entity-relation data model for integrating spatio-temporal data is designed.In the design,spatio-temporal data can be effectively stored and s
This paper aims at multi-scale representation of urban GIS,presenting a model to dynamically generalize the building on the basis of Delaunay triangulation mode
The LAMBDA methodthat was proposed by Teunissen is introduced. Then, on the basis of both the back-sequential conditional LS technique and the upper-triangular
