On evaluation of 3-D geospatial modeling systems

Systems for 3-D geospatial modeling are becoming mature. Before they can be put to practical use, it is essential to be able to characterize their performance for the purposes of scientific evaluation and their utility to a user. It is also important to be able to predict performance for new examples. The evaluation metrics need to be simple enough to be readily comprehensible but still to capture the important relevant performance parameters. Some evaluation methods are proposed in this paper. A distinction is made between detecting objects and their accurate delineation.
