OpenStreetMap User Guide
If you have been following our OpenStreetMap topic over the past few months then I am sure you have come to the realize that it is a community driven project and that anyone can edit OpenStreetMaps. But where does one start?
Below are some resource documents to help you get started using OpenStreetMap created by LearnOSM. These documents provide easy to understand, step-by-step guides that will explain how you can start contributing to OpenStreetMap and using OpenStreetMap data in your projects.
The beginner guide provides step by step instructions to help users get started with OpenStreetMap. It teaches how to create a free account, how to use the map editing tools, and how to collect information to create custom maps with.

Have you ever thought where you would end up if you drilled a tunnel through the center of the Earth and climbed out the other side? Well that location is considered an antipodal point. The antipodes of any place on a globe is the point on the surface which is diametrically opposite to it. Two points that are antipodal to each other are connected by a straight line connecting through the center.
Mathematically, the geographical coordinates of an antipodal point can be calculate as: the latitude of the place you want to find the antipodes must be converted to the opposite hemisphere (eg: 45° North will be 45° South or -45°); the longitude of the place you want to find the antipodes must be subtracted from 180° and the result will be converted to opposite hemisphere (eg: 25° West will be 180° – 25° = 155° East or -155°).
The majority of locations on land do not have land-based antipodes.
In 2013 I wrote an article for GoGeomatics magazine about an interactive maps that revealed what the Antipodes for any given location was. It has turned out to be one of the busiest articles in the magazine, attracting a lot of attention, perhaps because many geomatics people have not taken many geography courses.
The site that I was referencing to in the article seemed to have disappeared some time last winter, therefore no one could use the interactive antipodes calculator. Well now the site is once again active and people can once again learn a little bit of geography in a funny and simple way.
So check out http://www.antipodesmap.com to have a little fun exploring their interactive antipode calculator map.
Helping Children Learn Cartography
Where in the world are you? Learn to read, understand and create maps
Recently at a yard sale, we discovered this simple book for kids that teaches them about the Art of Mapping called “Maps and Mapping for Canadian Kids” and thought we would include it in our Geo-Books section for others to discover and use when they are trying to introduce kids to maps.

- Authors: Laura Peetoom & Paul Heersink
- Toronto, ON: Scholastic Canada, 2011.
- 38 pages, paperback
- ISBN 978-1-4431-0493-7

Maps and Mapping for Canadian Kids
Children can learn to read, understand and create maps using this easy to follow Scholastic book by Laura Peetoom & Paul Heersink.
Maps and Mapping for Canadian Kids helps introduce children to the basic elements used when reading a map including map scale, symbols, and colours. It makes use of vibrant colors, simple diagrams, and various pictures to help children easily understand the process of creating and reading maps.
It shows them how maps are made, how they work and teaches them how to read maps including basic principles of navigation and how early explorers were able to chart the world, and Canada in particular.
The book then goes beyond the basic elements of maps providing some deeper aspects of cartography such as the minimum amount of colors to use when creating a map to the meaning of contour lines on topographic maps. It also includes a special section about explorer David Thompson highlighting some of his achievements as a great Canadian cartographer. This is a really great resource to use when introducing your children to what maps are, and how to create one.
A map is a picture of a place, but not like a painting or a photograph, which shows us what a place looks like. A map is a picture of information about a place. (p. 4)
The earliest known maps of Canada were drawn by seafaring explorers from Europe. Our whole continent was a surprise to them. When they found it, they were looking for something else – an easy passage to India and China.
So early maps of North America highlight information useful to readers looking for a way through: the shape of coastlines, the location of waterways and how far they travelled into the land. (p. 14)
The word “map” comes from the Latin word ‘mappa,’ meaning cloth. In earlier times, maps were drawn on animal skin or cloth. “Cartography” was borrowed from French: ‘cartographie’ means “map drawing.” (p. 16)
