| Apr 30, 2014 at 17:52 | comment | added | Chris W | After some testing I found the method won't work well enough to justify using. The point of separated feature classes was to allow overlapping shapes so that their edges could blend together using transparency, since that effect only works between layers and not within a single layer. However the transparency mode isn't adjustable in that aspect of ArcGIS - even with two layers at 50%, the upper layer has distinct dominance over the lower (overlay vs blend). The method also uses gradients as radouxju posted in the interim, but had another issue I'll cover in a comment to his answer. | |

| Apr 29, 2014 at 7:17 | comment | added | Chris W | Do the colors need to blend/cross the boundaries, or just fade up to the boundary? Is splitting the polys to separate feature classes by value an option? Without going to raster, I don't think it's possible in ArcGIS to overlap shapes in the same feature class and see both, even with transparency (something that's been driving me nuts for a couple of weeks now). I do have a way to get the soft edges though, and with separated feature classes it should work to blend them together. | |

| Apr 28, 2014 at 23:59 | comment | added | PolyGeo♦ | I found a similar requirement at forums.esri.com/Thread.asp?c=93&f=1730&t=303003 but am not certain whether the link from there (blogs.esri.com/esri/arcgis/2008/10/14/…) may lead you somewhere useful ... | |

I'm thinking start with a buffer negative a few hundred metres then a distance raster but not sure how to transition the colours from that. In the end I think that you will need a raster to display properly but might need to do some clever maths for the transition. I think it might be best to prepare a raster layer in PhotoShop using the blend (use worlded TIFF and the georeference isn't destroyed). | |
