AHGW:Definition Query Filter
The Definition Query Filter tool simplifies working, visualizing, and analyzing data within the groundwater geodatabase by filtering a layer based on its FType attribute. For example, a set of wells imported from a state database may contain wells of multiple types (e.g. irrigation, water supply, domestic, monitoring etc.). The well type is defined in the FType field. When visualizing and analyzing the well data it might be useful to analyze only certain types of wells. The Definition Query Filter tool makes it easy for users to create filter selected datastes to include only certain types of data.
By choosing the appropriate option in a combo box located on the Arc Hydro Groundwater toolbar, the layer can be immediately filtered based on its FType attribute.
