Yellow Brick Road

It's been more than a month since my last update, but interesting research has been going on behind scenes. Yesterday I gave a shot at using real world terrain data to generate height maps, from SRTM data. Thanks NASA! The data is nearly 15 years old, and the accuracy isn't top of the line these days, but it is exciting to see real world terrain in UE4! There are a few companies which sell higher quality images. Nasa's data is accurate to 90m per pixel. New terrain data being sold is accurate to sub meter accuracy. Although, these options are pricey and will remain out of reach for the time being. Perhaps in the future it will be possible to map the UK far beyond this video, but at least we have a start!
