This report was prepared in conjunction with Research Initiative No. 1 of the National Center for Geographic Information and Analysis (NCGIA). It is being distributed as an aid to research. The report consists of a review of a body of literature focused on the issue of spatial database accuracy. The error taxonomy developed in the report organizes different dimensions of accuracy into a practical, user-oriented structure that reflects the interests of those conducting both pure and applied research. A less-detailed discussion of this same body of literature is provided in NCGIA Technical Paper 89-9.
