In this paper, we present an object-oriented library which provides an open-ended tool for handling multiresolution representations of field data in arbitrary dimensions. The library is fully parametric on the dimensions of the field domain and co-domain, on the attributes that can be associated with the model, on the criteria used for building the model, and on the criteria used for extracting representations at variable resolution from it. The library offers a basis for the development of GIS applications involving both two-dimensional and three-dimensional data, which can benefit from the use of multiresolution techniques.
