📙An interesting paper on spatial data science languages

"GeoJSON specification prescribes to handle all geodetic coordinates as Cartesian in the rectangle bound by POINT(x=−180 y=−90) and POINT(x= 180 y= 90)...and one wonders how many users of GeoJSON are aware of these explicit intentions." I was not aware of these explicit intentions 🤔
