Query Map Data

The Analysis | Query | Data command allows you to perform map queries based upon statistics of the map's data. In order to use the Analysis | Query | Data command, you must have a thematic map or a pin map on the active map layer. You can query the map and return results based upon statistics on all the map data, such as finding the three objects with data values closest to the mean, or you can query the map based upon the data value for a single boundary object. For example, you can identify a map object and quickly find three other map objects with data values closest to the identified object.


Query Map Data Dialog


Query map data and select the desired action for queried objects in the Query Map Data dialog.



In the Query Map Data dialog, the Action group determines what to search for with the query. This group also controls how the results of the query are to be displayed. The combination of all the settings in the Action group reads like a sentence, indicating what the query will do.


The list on the left side of the Action group contains all of the available methods for displaying your query results.


The next field in the Action group defines how many objects you want to find that meet the query criteria. Enter a numeric value into this field.


The last field in the Action group indicates the basis for the query. The objects closest to list displays all of the possible criteria you can use to query a map.


Limit Queried Objects

The Limit objects to box lists all the types of boundary objects that can be used to create thematic symbols of the map type on the current layer. To select or deselect an object type, click on the appropriate text. A query only operates on the object types selected in the Limit objects to box.



The Data Statistics box shows statistics for the selected variable used in the query. Thematic maps using a single variable, such as a hatch map, have one variable in the Data statistics list. A map with multiple variables such as a bar map have show all of the mapped variables in the Data statistics list.



If you would like to see the data associated with selected objects, use Analysis | Make Report | Record Report | Boundary. Alternatively, you can use Create worksheet with.
