With text written in English we have a pattern of reading, left to right, top to bottom, but with maps we have a different kind of a pattern of reading. The map is presented to the map reader all at once – but it is up to us, the mapmaker, to put the most important information in a place that it will be seen first. 


Since cartography is a mix or art and science I think of maps as a piece of art. We can use some cues from the art world when thinking about how our map is read.


The rules differ for a painting versus a photograph; I consider maps to be more similar to a painting so I use the rules that apply to paintings.


Eye Movement


When we look at a piece of art, our eyes tend to two places first - either the top-left or top-right of the frame – if you look at paintings we can see a pattern of how artists use a bold splash of color or an absence of color to draw the eye into the painting. Next time you are at an art gallery I encourage you to see what paintings grab your attention and why!


Looking at Vincent van Gogh's Starry Night we can see a fantastic example of how the moon draws our eye to the top-right of the painting...

Our eye then travels – usually – from the point of interest in a clockwise motion around the painting – reading it. We can see in van Gogh's painting we move down from the moon, across the village, our eye follows up the spire, and then the swirls bring us back to the moon. We do this whole process unconsciously in a split second. 



Since we are talking about cartography, let's see how it applied to this map!


Kevin Sheehan of Manuscript Maps was kind enough to let me use his hand-drawn map of the Gin Distilleries and Brands of Great Britain and Ireland as an example...



Looking at the map, our eye is drawn towards Scotland and the insets in the top right, naturally our eyes travel down the coastline of the UK until we reach the elaborate compass rose which, along it the inset of London, creates a focal point. Our eyes are drawn up along the coast of Ireland and across the text box of the history of Gin which brings us back around to where we started.



We can use another artistic composition technique....


Rule of Thirds


The rule of thirds is a theory – based on the Golden Ratio – involves drawing lines vertically and horizontally splitting the composition into thirds...



The idea is that we want to balance the composition so that there are no “lines” within our composition that match up with the third line (in red). If a line matches up -  like the edge of a box or a north arrow - it can throw off the composition of the map. If your maps looks "not quite right", try drawing these lines to see how it looks.


We can see with Kevin's map that no elements are aligned with those third lines...



I asked him if he uses the rule of thirds in his composition and he said, not intentionally, but since he studied art he is familiar with the concept. We can see that his design instincts mean that none of the inset edges or logo boxes match up with any of the third lines. I have applied this technique to all of Kevin's hand-drawn maps and they all pass the test. Once you practice working with the rule of thirds, it should become natural for you as well!


One more tip... When these third lines cross we also end up with an intersection. As a general rule you do not want map elements to be centered on these intersections. If a map element is centered at these intersections can draw the eye too much and throw the composition off balance.


Again with Kevin's map we can see that the text boxes and insets are offset from dead center of these intersection points. Aligning elements near but not centered on these intersection points creates visual interest.


Give these techniques a try and see if they help make your maps have a better visual balance!


Happy Mapping!






Thanks to Kevin Sheehan of Manuscript Maps!

In the upcoming release of ArcGIS 10.8 and ArcGIS Pro 2.5, the Spilhaus World Ocean Map in a Square will be supported as aprojected coordinate system based on the Adams square II map projection. 

Here is an ArcGIS StoryMap about how we uncovered and defined the projection, which shows the world’s oceans as a single body of water.

John Nelson already got his hands on it and made some maps. Here is his blog post Spilhaus? More like Thrillhaus.

The Equal Earth, an equal-area projection, and the Peirce quincuncial, a conformal projection, are now available in ArcGIS 10.7 and ArcGIS Pro 2.3.

The Equal Earth is an equal-area pseudocylindrical projection for world maps. It shows a pleasant appearance of the land features and its shape is similar to the well-known Robinson projection. The projection is appropriate for mapping global phenomena or for any other thematic world map that requires areas at their true relative sizes. It was jointly developed by Tom Patterson (US National Park Service, ret.), Bernhard Jenny (Monash University) and Bojan Šavrič (Esri) in 2018. It was published in IJGIS. Some behind-the-scenes look at how (and why!) it was created can also be found in ArcUser article.

The Peirce quincuncial map projection shows the world in a square. The projection is conformal except in the middle of the four sides of the square. It was developed by Charles S. Peirce in 1879. In his original design, the projection is centered at the North Pole, which displays the equator as a square rotated relative to the projection edge. The original implementation was on a sphere. Esri's implementation of this projection maintains its conformal properties on ellipsoids also such as WGS 1984. The projection can be tessellated or mosaicked.

Happy projecting!

ArcGIS 10.4 now supports eight small-scale map projections displayed in an animated gif:

Compact Miller
Natural Earth
Natural Earth II
Wagner IV
Wagner V
Wagner VII

The Eckert-Greifendorff, Wagner IV and Wagner VII are equal-area projections; the remaining five are compromise projections that try to minimize overall distortion. Sample definitions for the first seven projections are available in the Projected Coordinate Systems\World  and Projected Coordinate Systems\World(Sphere-based) folders.

The Eckert-Greifendorff, Wagner IV and Wagner VII also support ellipsoidal equations. Gnomonic, quartic authalic and Hammer projections are now available in ellipsoidal forms too.

With Eckert-Greifendorff, Hammer ellipsoidal, quartic authalic ellipsoidal, Wagner IV, and Wagner VII, one can select a custom central latitude and create oblique aspects of the projections.


ArcGIS 10.4 includes three variants of polar stereographic projection (variant A, B and C – EPSG codes 9810, 9829 and 9830 respectively) and two new variants of Mercator projection (variant A and C – EPSG codes 9804 and 1044 respectively). Mercator variant B (EPSG code 9805) was already included before as Mercator projection.

Mercator variants A and B have origin of northings / Y values at the equator. Variant A uses a scale factor at the equator to reduce overall scale distortion and effectively defines two standard parallels that are symmetric around the equator. Variant B takes a standard parallel and effectively forces the scale factor at the equator to be less than one. Variant C is similar to variant B, but with the addition of a latitude of origin. The origin of northings / Y values occurs at the latitude of origin.

The polar stereographic variant A is centered at a pole. The longitude of origin defines which longitude will be going straight “down” from the North Pole or “up” from the “South Pole” towards the middle of the map. A scale factor reduces the overall scale distortion and effectively defines a standard parallel. The variant B is similar to variant A, only that it takes a standard parallel to reduce the overall scale distortion of the projection and results in a scale factor at the pole of less than one. Variant C is similar to variant B, but with the addition of a latitude of origin. The origin of northings / Y values occurs at the intersection of the latitude of origin and the longitude of origin.
