Welcome to my Map Projections Series!

We all are familiar with coordinates as we all play this great game of geocaching, but how well do you know your map projections? Once you get the hang of solving these, you’ll be through them in a snap! This is my first attempt at a puzzle series – and I hope I’ve kept it pretty straightforward. Everything you need to solve is on this page. What’s in a name, anyway? Why, the names of some different projections of course!

In all cases 0 = 0

Ever heard of the book “How to Lie with Maps”? Well, these are just seven more common map projections of hundreds throughout the world. Each projection can be used to emphasize a different area, useage or focus. They portray all or part of the round Earth on a flat surface, which cannot be done with out some distortion. Every projection has its own set of advantages and disadvantages. There is no "best" projection. The key lies in mapmaker selecting the one best suited to the task at hand, reducing distortion of the most important features.

Mapmakers and mathematicians have devised almost limitless ways to project the image of the globe onto paper.

Robinson

The Robinson projection is a map projection of a world map, showing the entire world at once. It was specifically created in an attempt to find a good compromise to the problem of readily showing the whole globe as a flat image. Created by Arthur H. Robinson in 1961, and has been in use by Rand McNally since the 1960s and was used by the National Geographic Society between 1988 and 1998. The National Geographic Society now uses the Winkel tripel projection.

The Robinson projection is neither equal-area nor conformal, abandoning both for a compromise. The creator felt this produced a better overall view than could be achieved by adhering to either. The meridians curve gently, avoiding extremes, but thereby stretch the poles into long lines instead of leaving them as points.
Hence, distortion close to the poles is severe, but quickly declines to moderate levels moving away from them. The straight parallels imply severe angular distortion at the high latitudes toward the outer edges of the map, a fault inherent in any pseudocylindrical projection. However, at the time it was developed, the projection effectively met Rand McNally's goal to produce appealing depictions of the entire world.

I decided to go about it backwards. … I started with a kind of artistic approach. I visualized the best-looking shapes and sizes. I worked with the variables until it got to the point where, if I changed one of them, it didn't get any better. Then I figured out the mathematical formula to produce that effect. Most mapmakers start with the mathematics. —1988 NY Times article


********************************************************

All these placements were Winter Friendly when hiddden but one or two may not be if we get more than a foot of snow - for those caches, check the attributes; they won't be listed as winter friendly. Also, come spring some may require a little more bush stomping and might be in slightly wet areas - I'll update the attributes/comments when the snow melts and I can see the conditions.

The parking coordinates provide a good starting point to walk the entire series.
