I have a table of polygons representing travel time isochrones on particular days. For each origin point, there are five isochrone geometries (stored in separate rows). For each origin point, I want to rasterise the five isochrones (a binary NULL or 1), and then combine them into a single raster...

R has the capacity for image segmentation, although all of the examples I have come across utilize a single band for the segmentation (example). I am interested in combining R's capacity for random forest image classification with an object-oriented segmentation approach. What functionality...
