Book Review: Cartographer’s Toolkit

The Cartographer’s Toolkit: Colors, Typography, Patterns by Gretchen N. Peterson is a collection of color palettes, typography, and other map components arranged in an easy to reference manner.It will be useful for those who wish to (and have the opportunity to) design more sophisticated maps.

Book Review: The World of Gerard Mercator

“The World of Gerard Mercator” by Andrew Taylor is an excellent biography of Gerard Mercator – someone who we have all heard of, but generally know very little. Taylor does a good job of putting him into both a historic and a cartographic context, and does his best to explain Mercator with the relatively limited ...

Polar Maps and Projections: Part 2, Implementation 2

The first part of this article looked at different ways of producing polar maps and surveyed a number of different azimuthal projections that are often used for polar maps. In this second part, I produce a working implementation using UMN MapServer and OpenLayers.

Polar Maps and Projections: Part 1, Overview

With the success of my earlier series on global equal area map projections (starting with this overview), I received a number of requests to produce a similar how-to article for polar maps. The first part of this article (published here) provides an overview of a number of different map projections commonly used for polar maps. ...

Choosing a Projection, Part 3: Pseudo-Cylindrical Projections

After looking at the need for global equal area projections and a number of different possible projections, we shall now look at the pseudo-cylindrical options. There are a lot more of these, so we cover them in an article of their own. Pseudo-cylindrical projections are similar to cylindrical projections, but the central meridian is the ...

Choosing a Projection, Part 2: Pseudo-Conic, Azimuthal, and Cylindrical Projections

In the first part of this article, I argued against the use of Mercator and Equirectangular projections for web maps showing global data distributions and areas. Instead, an equal area projection is more appropriate because it preserves relative areas and data densities. In the final two parts, I shall look at some possible equal area ...

Choosing a Map Projection: Part 1

Previously in this series (1, 2), we discussed the different map projections and coordinate systems that can be used for map generation. We also looked at the reasons for the many different projections, and some of the reasons why we might wish to choose a different projection. In this article, I shall make the case ...
