QGIS does not have the coordinate reference system I need, So I decide to define a new custom Geographic coordinate system. To define a CRS, I selected customProjection Custom CRS from the Settings menu. The Custom Coordinate Reference System Definition dialog requires only two parameters to define a user CRS: 1) A descriptive name 2) The cartographic parameters in PROJ.4 format
But when I click OK to add the projection within QGIS a pop up message with an error show up and with very different set of parameters in the parameter window. the error message says I have set up a proj string definition equivalent to esri:102218 which is not really the same. I don't really know if this a bug or something went wrong with my parameter setting.
