Comparison of FOSS4G supported equal-area projections

Copyright (c) 2018-2019 Luís Moreira de Sousa. All rights reserved. Any use of this software constitutes full acceptance of all terms of the document licence.


This set of programmes compares the performance of five equal-area projections supported by Free and Open Source Software for Geo-spatial (FOSS4G):

  • Sinusoidal
  • Mollweide
  • Hammer
  • Eckert IV
  • Homolosine

The comparison is made using discrete distortion indicatrices positioned on the ellipsoid according to a Icosahedral Snyder Equal-area Grid (ISEAG).


This suite of programmes is released under the EUPL 1.2 licence. For full details please consult the LICENCE file.
