 The workshop will demonstrate how to create a custom "globe" in the classroom with QGIS, helping students understand how map projections work.
 
+**IMPORTANT ADDITIONAL NOTES**:
+
+_This workshop is intended to properly describe names "cylindrical projections" and "conical projections"._
+
+_Cylindrical projections are not suitable for world maps because of the large deformations near the poles. Parallels are circles that get smaller and smaller as we approach the poles, and in cylindrical projections all images of parallels are the same length as the image of the equator._
+_Please read: Robinson A. H. (1990): Rectangular world maps − no!, Professional Geographer, v. 42, no. 1, p. 101-104. (Opposes general use of cylindrical projections for world maps)._
+
+_Conical projections do not need to be applied to hemisphere - they can be applied to either smaller or bigger part of hemisphere or to entire sphere - for example, one can use equidistant conic projection along all meridians (ESRI:54027)._
