Both fields have weird coordinates
|
|
In both, pixels are more than RGB
|
|
In both cases, the (RGB) colour in the screen is a function of the data for each pixel...
...so videogames are doing raster algebra, after all.

The big difference
GIS → Accuracy
«Acc worse than 0.5cm is
|
Games → Speed
«OMG this game doesn't run at 60FPS 4K on my 100Hz HDR 46' ultrawide screen»
|
Convergence & opportunity
GIS is faster because tiles
|
GPUs are more accurate because convolution-driven neural networks to perform image recognition on cat photos
|
Sweet spot:
Videogames have been doing raster algebra better and a hundred times faster than any GIS software for years.
Challenges
GIS has a lot of baggage
|
GL tech is deeply entrenched in high-level frameworks
