This is great thanks, however!..... I am using two tiles to get the area I'm interested in. The first pair of DSM and DTM work great. But when I do the second pair it just goes white. Like I've subtracted everything! I have double checked the layers and they are visually different, one a terrain and the other surface info. Does this mean anything to you?
Hi Ceballos, the building outlines are from the Ordnance Survey's Open Map Local, which you can download for free from www.ordnancesurvey.co.uk/opendatadownload/products.html
Amazing. Thank you.

Hi AMDGS can please add the links to videos of the digital terrain model (DTM) and digital surface model (DSM)?
This is so helpful, thank you!
Hi AMDGS, can you provide the source where you pulled out the vector layer with the buildings?
