how to convert spherical projection to flat? images attached

Discussion created by spectralsepia on Apr 21, 2011
i am using free data and an error message says this layer, shipping routes (source: transformed geotiff [the ESRI grid file will not open] from http://www.nceas.ucsb.edu/globalmarine/impacts), cannot be projected. It draws as a sphere (see attached pdf) and im trying to make it flat. i am assuming this is because it is a tiff but any help would be great! thanks!!
