Abstract
This paper presents some basic properties of reduction and covering upper approximation of Rough sets. Three kinds of coveringrough set have studied: Semi-reduced, Pointwise-covered and Unary. Some conditions for two covers generating the same covering lower andupper approximations and relationship between closure mappings and three types of upper covering approximation are identical
