  • Thanks Alvesgaspar! Such a nice coment from a cartographer is always very valuable and pleasing. The projection is an Albers equal-area and the linear scale along the meridians is not constant like it could be in a polyconic projection for example. That's why, in a search of precision, I indicate the horizontal linear scale variation between the top and the bottom of the map. And thanks to all for supporting my work!

  • In the Albers projection the scale along the meridians does not vary linearly: it reaches a maximum value at the standard parallel (or at a latitude situated between the two standard parallels), decreasing from there to north (to 0, at the pole) and to south. In my opinion the graphical scale should reflect only the principal scale of the chart (which is the scale along the standard parallels) and the latitudes of the standard parallels should be identified in the legend. Any other solution is confusing. By the way, the scale along the meridians is not constant in the polyconic projection; but the scale along parallels is! Carry on with the good job! -- Alvesgaspar (talk) 00:22, 3 December 2010 (UTC)[reply]
