But you may discover that the data set you want is buried with a lot of other data; it may have an obscure name; the data sets you find may not meet your standards, even if they cover the correct subject and correct geographical area. A major feature of ArcCatalog is the capability to help you discover spatial data sets and, through inspection of their metadata, determine if they meet your needs. Assume that a client or your supervisor asks you to find all the geographic data that could apply to the Wildcat Boat project. You begin by setting up ArcGIS to search your personal folder.
