The current state of mapping efforts.

BlueMarble projections

edit

I tried making some better-looking maps. In dimensions where scaling was linear, Lanczos3 brought pretty decent results. In other dimensions, it sucked, making a map blurred. There's probably some math behind it -   and   ( ) are orthogonal over   with  . This is not necessarily the case for different weighting function. And non-zero scalar product = blurred results.

  • cylindrical equidistant - linear in both dimensions, transforms for each dimension independent
  • cylindrical equalarea - linear in one dimension, transforms for each dimension independent
  • cylindrical Mercator - linear in one dimension, transforms for each dimension independent
  • azimuthal - nonlinear in both dimensions, transforms for each dimension not independent

Other problems

edit
  1. no decent library that would do all the graphics, especially the font-related graphics.
  2. no decent country label placement
  3. city data doesn't specify which X is "the X" and which is "just some village that happens to be called X too"
  4. country borders are not up-to-date and politically correct
  5. rivers data is buggy
  6. not enough sub-country administrative divisions data

Relations between problems:

  • 2 can't be solved until 1 is solved
  • 3,4,5 possible to do by hand with quite a bit of effort
  • no idea how to fix 6
