Abstract

Fuzzy set approaches are particularly suitable for issues of modeling uncertainty in spatial data. The authors survey where and how uncertainty may appear in spatial data. They consider the issues involved in developing the modeling of uncertain spatial data in the framework of object-oriented databases. Finally they outline the issues in an approach for implementing fuzzy spatial queries in a commercially available object-oriented database
