Abstract
It is very useful to select lunar features by query not only on a region but on land names. However, there are no any convenient system that searches lunar features from lunar names in domestic and overseas system. Therefore, we are starting construction of lunar nomenclature search system based on QBO (Query-By-Object) approach. Using this method, we can designate specific points of the moon using nearby name by lunar feature names. Currently, we are focusing on the region including Copernicus crater. In this lecture, we report our progress and future strategy.
