It evaluates the geometry's bounding envelope and selects an SRID that optimally represents the geometry on the Earth's surface. The function prioritizes Universal Transverse Mercator (UTM), Lambert Azimuthal Equal Area (LAEA), or falls back to the Mercator projection. + +- For geometries in the Arctic or Antarctic regions, the Lambert Azimuthal Equal Area projection is used. +- For geometries that fit within a single UTM zone and do not cross the International Date Line, a corresponding UTM SRID is chosen. +- In cases where none of the above conditions are met, or for geometries that cross the International Date Line, the function defaults to the Mercator projection. Review Comment: I've not found how the data line was handled in the implementation. Would you please point out where the date line was handled in `bestSRID` function? -- This is an automated message from the Apache Git Service.
