SCALELEVEL
Definition: Scale Level. A numeric code that defines scale range levels for features. Scale Level values range from 1 to 6. More features are included in the higher Scale Levels. For example, Scale Level 1 includes only a few major rivers and is intended for a small map of Connecticut. Conversely, Scale Level 6 includes all waterbodies and is intended for more detailed maps displayed at about 1:24,000 scale. Use the Scale Level attribute to specify a definition query that displays a particular set of features, for example SCALELEVEL = 1. Then set the appropriate range of scale (e.g. from 1,000,001 to 3,000,000 scale) for the layer, according to application (mapping) need. Note, Scale Levels are additive so include all Scale Levels below the desired level in a definition query. For example, use the following SQL expression to query for Scale Level 4 features - SCALELEVEL IN (1,2,3,4). Note the use of the IN (INCLUDE) operator in the SQL expression.
