Hi, all building heights are sourced from skyscrapercentre.com which source their information from architectural plans of the building.
View Tower for example is shown to be 107m in height above ground level:

Regarding your second paragraph, does this mean that to make 3D rendering more accurate, the number that I input in the height tag should be the ele (90) + height (107) (so 197), or just the height input (107) from the source?
Thanks for your help.
