Thanks, daan!

Hi daan,

Could the Equal Earth projection be added to Geocart?

Hi daan,

Thanks for the explanation concerning Ginzburg VIII, etc. As a side note, it seems that John Snyder distinguishes true pseudocylindricals from "regular" pseudocylindricals (Flattening the Earth, 1993, page 189).

Hi daan, Ellipsoidal should have been elliptical (e.g., Mollweide), and spherical should have been globular. As for "sinusoidal (anti-)meridian", I was thinking of Bojan Savric's distinction between elliptical and sinusoidal shapes for meridian lines in his study "User preferences for...

A filter for restricting the projections that are displayed or selectable in the Change Projection dialog would be useful. The filtering could be based on distortion characteristics and other properties. Possible inclusion/exclusion criteria could be: Extent of the area displayed: entire sphere or a...

Thanks, daan. This would be a useful feature.

Hello daan, Yes, that is what I was thinking of. A batch process that can read, project, and write individual frames in numbered raster images would work as well. This would be useful for video maps such as this one: http://svs.gsfc.nasa.gov/cgi-bin/details.cgi?aid=11719 Here is an interactive versi...

daan,

Is there a way in Geocart to project a video file from Plate Carrée to another projection?

Thanks,
Bernie

Thank you daan.

I would like to learn more about the derivation and mathematics of the lenticular Strebe 1995 projection.

Is there any public documentation available?
