The Goode Homolosine Projection§, invented by J. Paul Goode in 1916,  is actually a composite of two earlier projections. The Sinusoidal Projection, first shown by Jean Cossin of Dieppe in 1570, is used for the middle latitudes. The Mollweide (or "Homolographic") Projection, introduced by Carl B. Mollweide in 1805, is used at latitudes above 40°N and 40°S. Both are equal-area pseudocylindrical projections, showing parallels as unequally spaced straight lines parallel to each other, meridians as equally spaced curves, and poles as points.  The meridians of the Sinusoidal Projection are sine curves, while those of the Mollweide Projection are ellipses.  The version shown here is interrupted into twelve regions to display the continents with minimal distortion.  Other interruptions are used to show Asia or the oceans to better advantage.

If you don’t have Whip! you can still see the JPGs, but to fully appreciate these engineering-quality maps, download and install the free Whip! viewer plug-in (3.5MB).  You will then be able to see the scalable vector versions of select maps.
Click on the Vector Map link on each page to view the DWF file.  You can pan around and zoom in on them, because they are true scaleable vector drawings.  Using the Right Click menu, you can even turn layers on and off individually.
The extreme precision and detail of these maps cannot be reproduced in raster formats.  The world maps are designed to be plotted at sizes up to 24” by 36” by robotic pen plotter. Some of the oil and gas maps were designed to be viewed up close when plotted at 300 dpi, at sizes up to 3 feet by 10 feet. The size of a BMP file of that scale would be approximately 1.5 gigabytes.
If you have limited bandwidth, be aware that the DWF files contained in this site range from about 100KB to about 750KB.
