Wispmon Qualify Pro does this as well. It's what it was made for. However, the clutter data in any of these are only categories, and not very good ones at that. It seems they've all standardized on the small subset of categories used in RM. There are much more detailed clutter databases with hundreds of categories in them, but they are not used in this industry mostly due to cost and "it's just not what people are used to". It is up to the end user to define the "elevation" per category. Obviously, this would be an average height of trees, etc, in those categories. There is no clutter height database as it would need to change so often it would not be practical. Qualify Pro allows you to move your mouse along the profile and shows the same position on the map, so that you can see from an aerial or sat view, exactly what it is causing the obstruction. IF you know your area, you can probably be within about 85% certainty of the potential for obstruction using this method.
All of these tools, Qualify Pro, Heywhatsthat, RM, google earth, towercoverage, etc. are great for making an educated guess, but if there is any doubt, you should go check it out yourself before making a large investment in equipment.
