Web1 Answer Sorted by: 10 If your data is in Geographic Coordinate System (WGS84 etc..), the units will be in decimal degrees (angular). So I would project the polygon shapefile first to a Coordinate System with Meter as unit (like NAD83 UTM Zones..). Then the buffer distance will be in meters. WebSince we need to perform 10 selections, the cost is 3*10=30 and the result has 100 tuples. (c) Join the result with Item using the unclustered hash index on Name. Since Name is a key, each hash brings 1 tuple and costs 1.2 (the cost of the hash) + 1 (the cost of retrieving the matching tuple) = 2.2 I/Os.
