Anyone have any pointers on generating building shadows that look better than just drop shadows using Arc?
Are you going to be using only
Arc to make these buildings shadows or do you have other graphics software?
I used to make fuzzy boundaries in GIS using the attributes from concentric buffers of features - if you make a buffer of 10 rings spaced 1m apart you can generate a range of numbers from 10 - 100 in a number field by multiplying the [ToBufDist] field by 10. If you apply the values in advanced symbology as transparency then you will get a gradually expanding shape that becomes increasingly transparent as opposed to just getting paler.
I tried to apply the same sort of thing to buildings but it's not perfect. In the example above I made three classes of building based on area and made larger buffers for each class (3 6, and 9m) and then clipped it with a shape made from copy-offsets of the building footprints. It sort of works but it's far from ideal
- the buffers gradully get bigger (obviously!) so some of the shapes expand into areas they shouldn't but the transparency effect works. I guess if you copy-offset the buildings and calculate transparency values as you go it would look better.
