Has anyone developed a measure area tool that displays the area 'so far' as you are drawing the polygon graphic?
I have got the measure area tool working fine, so when you double click to complete the polygon the area and perimeter are displayed to the user, but they have asked for the tool to update the area and perimeter dynamically as the shape is being drawn, so they know how big to draw a shape of a certain size.
I have seen this functionality on other mapping API web sites. Any help would be great, thank you,
Mark.
