EPSG:17774

Equi7 projection - Europe

Attributes

Data source: EPSG

Information source: "Optimisation of global grids for high-resolution remote sensing data", Bernhard Bauer-Marschallinger, Technical University of Vienna.

Revision date: 2024-01-04

Scope: Continental mapping of raster data.

Remarks: Basis for the Equi7 grid for Europe. Designed in 2014 to efficiently handle the archiving, processing, and displaying of high resolution raster data over land while preserving geometric accuracy. The projection is neither conformal nor equal-area.

Method: Azimuthal Equidistant

Area of use: Europe including Russia west of the Ural Mountains.
