    In fact, the Mercator projection was the first projection regularly identified in atlases. It is a cylindrical map projection that is a product of its time. During the sixteenth century, new geographic information was pouring in from around the world, trade routes were being established, and sailors, explorers, and merchants needed accurate maps. In Mercator published a 14 by 21 inch (36 by 55 cm) world map, laid down on the double cordiform (double heart-shaped) projection (fig. ) pioneered in by the French mathematician Oronce Fine (). Although Mercator borrowed the geographic framework from Fine, his map is more similar in content to Frisius’s terrestrial globe.

    These variants of the Mercator projection position the world so that the Prime Meridian (0° longitude) lies in the center of the map view. Among other criticisms of the projection, this particular world view can present a problem if you are trying to display data that is located in region of the Pacific Ocean.

    The Mercator projection was invented for sailors, who, thanks to its design, could use it to plot a straight-line course from their point of origin to their : Cara Giaimo.   The Mercator map has always been inadequate as a world map due to its rectangular grid and shape, but geographically illiterate publishers once found it useful for designing wall, atlas, and book maps, even maps found in newspapers published by non-geographers. It became the standard map projection for most applications and is still cemented as Author: Matt Rosenberg.

Apparently Mercator's use of italics was almost as influential as his projection of the globe (which he may have developed This book is an immensely detailed biography.

It's probably too detailed to be of much interest to a general reader. In fact, I'm not entirely sure if this book is all that readable outside of an academic setting/5. Well, lo and behold, Mercator was a person, Gerardus Mercator, not just a projection.

This is a terrific book for anyone interested in history that goes beyond the ordinary. In fact, there have been a lot of books about scientific history and this is a worthy addition to the by: refer to [3] or the more specialized book [1] on cartography for a wealth of information.

2 The Mercator projection As outlined in the introduction, Mercator’s idea was to map the sphere onto the plane such that the following properties hold: (i)the north{south direction is the vertical direction. Mercator projection 35 Meridians and parallels 35 Mercator mapping equations 36 Finding (x,y) 36 Point scale factor and convergence 37 of the meridian Finding (O,X) 37 Accuracy Mercator projection book Area of coverage 38 Mercator projection book Mercator (TM) projection 38 vCited by: The implementation of Mercator auxiliary sphere has sphere equations only.

In addition, it has a projection parameter that identifies what to use for the sphere radius if the geographic coordinate system is ellipsoidal based.

The default value of zero (0) uses the semimajor axis. Projection method. This is a cylindrical projection. Mercator projection, type of map projection introduced in by Gerardus Mercator. It is often described as a cylindrical projection, but it must be derived mathematically.

The meridians are equally spaced parallel vertical lines, and the parallels of latitude are parallel horizontal straight lines that are spaced farther and farther apart as their distance from the Equator increases.

For example, the basic Mercator projection is unique; it yields the only map on which a straight line drawn anywhere within its bounds shows a particular type of direction, but distances and areas areFile Size: 1MB.

In many ways the past debates over the Mercator are moot: arguing over the right projection for wall-sized world maps—Mercator vs.

Peters vs. Robinson—is fighting the last war. Mercator has become the default option for online mapmaking, simply because so many data visualization maps rely on Google Maps or OpenStreetMap for their base map.

Mercator's editions of Ptolemy and his theological writings were in print for many years after the demise of the atlas but they too eventually disappeared and it was the Mercator projection which emerged as his sole and greatest : Geert de Kremer, 5 MarchRupelmonde.

In a Mercator projection, latitude and longitude are both represented as straight, parallel lines intersecting at right angles (Figure ). This projection is good for navigation as directions are preserved; for example, on any point on the map, north points to the top of the chart.

Mercator's Projection reconciled the sphere and the plane, while his Atlas enveloped the world with an integrated system of maps.

In the midst of an era of. The Mercator projection is a cylindrical map projection presented by the Flemish geographer and cartographer Gerardus Mercator in This map projection is practical for nautical applications due to its ability to represent lines of constant course, known as rhumb lines, as straight segments that conserve the angles with the meridians.

Many have noted, for example, how the distortion. Page - PROJECTION Space oblique Mercator projection The launching of an Earth-sensing satellite by the National Aeronautics and Space Administration (NASA) in led to a new era of continuing mapping from space.

This satellite, first called -1 and then renamed Landsat 1 inwas followed by two others, all of which. While it’s well known that the mercator projection distorts the world, the maps here show very clearly by how much.

Countries close to the equator barely change, whereas countries further north shrink dramatically. The maps are all the work of climate data scientist @neilrkaye. You can see an animation below. In the third part of a ground-breaking work was published, a work which was to make history, quite literally of our view of the world: Gerhard Mercator called it an "Atlas" and by doing so, christened a certain kind of book, which still today is a synonym for a bound set of maps as well as a comprehensive and generic term for a whole science.

You see it every time you pick up an atlas and look at a world map with all its longitude and latitudelo and behold, Mercator was a person, Gerardus Mercator, not just a is a terrific book for anyone interested in history that goes beyond the ordinary/5(5).

Years ago during one of my many excursions into the history of mathematics I wondered how Mercator used logarithms in his map projection (introduced in a map) when logarithms were not discovered by John Napier () and published in his book Mirifici Logarithmorum Canonis Descriptio untilthree years before his death in The mystery was solved when I read a book .You searched for: mercator projection!
