I have lines (rivers) that don't exactly match a raster grid (flow accumulation). If they were exact, I could just extract the raster values to points I put along those lines. However the raster values I want are often a few pixels away. Luckily the raster value I want are much larger than the surrounding pixel values. There used to be a tool that you could use to extract the maximum pixel value within a set distance from your point... but I can't remember the name of the tool.
