building a 3d world globe
I found these instruction on internet about which projections are needed to build a 3d earth globe:
"Create a series of 12 Transverse Mercator projections that are 32 degrees in longitude and 91 degrees in latitude to form a "flower petal" projection for making globes. If the northern hemisphere is being created, the latitude range is -1 to +90. If the southern hemisphere is being created, the latitude range is -90 to 1. The petals are formed by changing the center longitude and map rotation in steps of 30 degrees for each Transverse Mercator projection. Each section is put into the mosaic. The final center of the projection is a Lambert Azimuthal Equal-area centered on the pole and covers from -90 to -75 or 75 to 90 degrees latitude and 360 degrees in longitude. This is the last cube that is placed in the mosaic"
But I can't find suitable (free) programs to obtain needed projections!
I need a Java or Windows program which any raster image input and produces raster output.
