Dear Group, I try to get a map in stereographic projection in transverse position (the centre of the map is point 0°latitude, 0°longitude). I have cartographic equations of this projection in wanted position. So I put them to WorldProjection: Miscellaneous'WorldPlot' WorldPlot [Europe, WorldRange->{{-90,90},{-90,90}}, WorldProjection->({2*Cos[#1*Pi/10800]*Sin[#2*Pi/10800]/ (1+Cos[#1*Pi/10800]*Cos[#2*Pi/10800]), 2*Sin[#1*Pi/10800]/ (1+Cos[#1*Pi/10800]*Cos[#2*Pi/10800])}&)] and I get from Mathematica 4.2: WorldGraphics::"badproj" : The projection function {....,...} did not return a valid coordinate... If I change Europe for another possible continent or state it gives the same type of error... If I change WorldRange for another possible it gives the same type of error... Is a problem in projection function and Why? I know from cartography textbooks that equations are correct... Any help would be appreciated. Thank you for your time and consideration. Hanka
