Unit: metre
Geodetic CRS: WGS 84
Datum: World Geodetic System 1984 ensemble
Data source: EPSG
Information source: "Optimisation of global grids for high-resolution remote sensing data", Bernhard Bauer-Marschallinger, Vienna University of Technology (TU Wien).
Revision date: 2024-01-04
Scope: Continental mapping of raster data.
Remarks: Basis for the Equi7 grid for South America. Designed in 2014 to efficiently handle the archiving, processing, and displaying of high resolution raster data over land while preserving geometric accuracy. Neither conformal nor equal-area.
Area of use: South America including Panama.
Coordinate system: Cartesian 2D CS. Axes: easting, northing (E,N). Orientations: east, north. UoM: m.
