Risc of change from old GRS 80 to WGS84? #7

Open ppKrauss opened 2 years ago

ppKrauss commented 2 years ago

The GRS80 was adoted by IGAC and implemented in our code as the "official near-equal-area projection of Colombia"... But, as commentd at Wikipedia,

The GRS 80 reference system was originally used by the WGS 84. The reference ellipsoid of WGS 84 now differs slightly due to later refinements.

So, please check with Colômbia (IGAC or other) if some plans to change from the old GRS80 to the modern and most popular WGS84.
