This tool performs queries about the data associated with the active layer. The active layer must also be made visible for this tool to work. You will be able to find and display specific feature attributes based on a query string you construct. To construct the string, select the field of your choice from the drop-down menu under "Field" in the query window. Similarly, elect the operand and the sample value. Then click the "Add to Query String" button to display the string in the adjacent window. (NOTE: you may type in your string from scratch provided you type in an existing field. You can also type in a value that does not exist in the sample list). Finally, click the "Execute button to view the resulting map.The map displayed will contain all matching records and the actual list of the records will be displayed in the query window. On the left of each record, are numbers that will link to the actual coordinates of each record. Click the relevant number to zoom to the record of your choice. You will also notice that at the bottom of the records list is a link that allows you to zoom to the full extent of all the records listed.
To clear the selection, click on the Clear Map tool . |
