ExprRef) The projection’s scale (zoom) factor, overriding automatic fitting. The default scale is projection-specific. The scale factor corresponds linearly to the distance between projected points; however, scale factor values are not equivalent across projections.

ExprRef) - tiltanyOf(float,
ExprRef) - translateanyOf(
Vector2number,ExprRef) The projection’s translation offset as a two-element array
[tx, ty].- typeanyOf(
ProjectionType,ExprRef) The cartographic projection to use. This value is case-insensitive, for example
"albers"and"Albers"indicate the same projection type. You can find all valid projection types in the documentation.Default value:
