Abstract:On the base of Mallet algorithm for wavelet transform, this paper provides a method for border processing of vector relief data condensation based on spline wavelet transform according to the properties of wavelet filters, And the experiments were given. Using the method, the condensation data can really express the properties and the rhythm of the origin data.
Keywords:B spline wavelet transform  border processing  vector map  data compression
