Question regarding the game map

Post by ncc1701e »

What was the map projection used to generate it?
Obviously this is not a Mercator one.

Thanks

These are the designer notes on the map as given in the manual---
The map is drawn using Azimuthal Equidistant projection, with a projection mid-point at 153 degrees East, 12 degrees North (near the island of Eniwetok in the Marshall Islands). This location is also the mid-point of the map itself. The scale used for War in the Pacific Admiral Edition is 40 nautical miles per hex.

The map was then adjusted in a few ways: it was compressed by 5% horizontally to match the vertical stretching of the hexes used in War in the Pacific (which are not true hexagons), then by another 5% overall to lessen the average base-to-base distance errors. As a result of these adjustments, and the use of a consistent projection, distance errors are, on average, lower than on the original map for War in the Pacific.

Finally, India and North America, which are located on the edges of the map, and are therefore subject to the greatest distortions, were reshaped by compressing them to make their distortions less evident. This also results in the distances between bases in these areas more accurate. These modifications result in slightly larger errors for long naval distances between ports in India or North America and other locations. In the view of the map designer, this is an acceptable compromise, which provides greater accuracy in land distances in India and North America, as well as a better aesthetic look.

Thanks, I should have checked the manual. But, I must be doing something wrong because with this projection, and centering, I can't see India.

That is because you are looking at a 2D image of a 3D world and you are not looking around the left side. Nor even on the right side since the East Coast of North America does not show up.

In the end all map projections have their issues, it purely depends on where you want to take the accuracy hit. In the design notes the developers did mention having to make some compromises. The ideal way to model this much of the globe's surface is vector-based mapping with a real curved world. Something that probably would have pushed the original drawn-out development of this game back to forever.
