We have a customer who really likes the measuring tool, but would like to see it's functionality combined with the line-drawing tool.
That is, they want to draw a line that starts at a point, and extends 6000 feet. They'd like to see the current length of the line being drawn displayed, while they are drawing. They aren't asking for the areas of polygons to be displayed, but that would be the obvious generalization. This strikes me as something that might be pretty easy to do, if you had sufficient insight into the design of OpenLayers. Any hints as to how to do it?
