Median Calculation in Rasterize

[dmbrubac]

Would it be possible to add Median to Min, Max and Average in the Projection - Cell Height calculation?

Median should be more resilient to spikes and would be a pretty easy implementation.

Thanks!

Easy indeed, but it would take a lot of memory (as you need to store all values to compute the median). I'll add it to the TODO list.

Thanks Daniel

The memory impact word get worse with the increasing cell size, that's true. I rarely have more than a few hundred points in a cell, though others may have more.

Is this still on the TODO list? A median filter raster would be very useful despite the high memory requirement.

I think it's still in the TODO list indeed.

Yes maybe memory is less an issue now (it all depends on the grid size of course)
