What is Formula Filter in vMAP?

vMAP’s Formula Filter calculates the different values (for example: sum, average, minimum or maximum) for a given field of any object type (point/line/polygon) and displays the results on the Formula panel simultaneously. If more than one object is selected, the values of the selected objects will be calculated and displayed. The calculation occurs simultaneously as objects are being selected from the mapview.

For example, you can calculate total sales volume of the stores, select more 10 stores from the mapview, their total sales volume will be calculated and displayed on the Formula panel.

The following calculations are available in vMAP:

• Count
• Sum up
• Average
• Maximum
• Minimum
