Top 7 maps that ultimately explain map projections Map projections are cool but they might be a bit scary. It’s difficult to understand how can you put a very complex round-shaped surface of the Earth on a flat plane. After reading this post everything should be clear! 1. Portraying the features of a spherical surface on a flat plane Map projection is portraying the features of a spherical surface on a flat plane. 2. This illustration from the book “Elements of map projection with applications to map and chart construction” written in 1921 by Charles H. 3. This amazing website is comparing parameters of key map projects. 4. Mercator projection is conformal so it preserve angles making it perfect for sailing navigation. Gall-Peters projection preserves areas. This equirectangular projection preserves distances. source: 5. When comparing conformal Mercator projection (black lines) and equal area Gall-Peters projection (green shapes) you can notice that the world as we know it from Google Maps is a lie. 6. 7. source: xkcd

Atlas historique gratuit - Site de atlas-historique-universel ! Etymology of African countries' names By hovering over the names, you will see the actual country's name and other possible etymologies. Why this map? This map was inspired by this etymological map of the USA. It does not claim to be exact; etymology is not an accurate science. 18th and 19th century armchair historians, geographers and linguists wrote countless books to explain the etymology of place names. Their idea was to explain the origin of Africans by tracing African languages back to a certain part of the world. The most famous example was the Hamitic hypothesis - if a toponym could be linked with Ham, son of Noah, it meant that an ethnic group in particular came from Egypt or the Middle East. A nonsensical map? This map aims at showing the variety of names used to designate African countries in modern English. Under a more historical angle, countries such as Burkina Faso chose to be called in 1984 the "land of Honest Men" as it was known under the colonial name of "Upper Volta" before. Why this projection?

The Map Room The Map Room is a blog that points to maps, map collections, map-related resources, and material about maps on the web. Anything that fits under that rubric, from medieval mappæ mundi to satellite imagery, and from topo maps to Tolkien, is fair game. Launched in March 2003, The Map Room is aimed at a broad audience. While cartographers and people in the geospatial industry seem to enjoy reading it, it’s meant to be accessible to anyone with nothing more than an interest in maps. Need more information?

Views of the World - worldmapping beyond mere description L'Antiquité en cartes animées - Vincent Boqueho raconte... l'Antiquité Je vous propose une incursion dans la Haute Antiquité, aux racines de l’Histoire, là où tout se met en place, là où émerge de par le monde le fil des civilisations qui se déroule jusqu’à aujourd’hui. La Haute Antiquité, c’est aussi 2800 ans d’Histoire, de 3300 à 525 avant J.C. : c’est-à-dire une durée plus longue que celle qui nous sépare de ces époques reculées. Lorsque le pharaon Psammétique III est détrôné par le Perse Cambyse II, les grandes pyramides de Gizeh sont déjà dressées depuis plus de 2000 ans : tout autant qu’aujourd’hui elles semblent issues du fond des âges, comme érigées par les dieux. Car la Haute Antiquité, c’est avant tout l’éclat de deux civilisations d’une précocité remarquable, héritières du Croissant Fertile : la Mésopotamie et l’Égypte. La haute Antiquité en 36 épisodes Notre collaborateur Vincent Boqueho enseigne les sciences à Nice. Et que dire de la civilisation de l’Indus, disparue entre 1900 et 1800 avant JC en emportant ses secrets avec elle ?

Un site très surprenant qui offre non seulement des reproductions de cartes anciennes de très bonnes qualitées, mais aussi la possibilité de les utiliser à travers Google Map afin de les mettre en 3D ou bien de comparer avec les cartes actuelles. by jeanfrancoisleblanc Jan 23
