> [The Global Human Settlement Layer (GHS) Population dataset 6.] is formatted as an image of 100m x 100m squares, each containing the estimated population residing in each square. [...] due to the unconventional projection used (Mollweide 7), the image appears slanted and skewed compared to a more traditional projection.
How do you divide a Mollweide projection into 100m x 100m squares? In fact, how do you divide any projected globe into 100m x 100m squares?! Do they actually mean 10,000 m2 squares? Because you could do that, they would just get narrower and longer towards the poles.
- wcedmisten 4y agoApologies for the confusion! I meant that the data is represented as an image (of square pixels). But you're right, the actual land that each pixel represents won't be a square. The dataset just says "100m resolution", so that may have been a misinterpretation on my part. https://ghsl.jrc.ec.europa.eu/download.php?ds=pop https://ghsl.jrc.ec.europa.eu/download.php?ds=pop
