New Advances in Error Simulation in Vector Geographical Databases

摘要

This paper presents new methods for attribute and positional error simulation in vector Geographical Information Systems, and discusses various issues related to this topic. Attribute errors are simulated according to a new statistical model. Positional errors are simulated with algorithms that take correlation into account and thus reduce topological problems that arise in classical simulations. These algorithms constitute a complete toolbox suitable for most purposes, especially accuracy assessment and sensitivity analysis.
