Launched on 17 March 2009, ESA's Gravity field and steady-state Ocean Circulation Explorer (GOCE) is bringing about a whole new level of understanding of one of Earth's most fundamental forces of nature: the gravity field. Dubbed the 'Formula 1' of satellites, GOCE is mapping Earth's gravity field in unprecedented detail.
This has given rise to a unique model of the 'geoid', which is the surface of an hypothetical global ocean in the absence of tides and currents, shaped only by gravity. It is a crucial reference for measuring ocean circulation and sea-level change, which are affected by climate change.
The colours in the image represent deviations in height ( -100 m to + 100 m) from an ideal geoid. The blue colours represent low values and the reds/yellows represent high values.
See also: Earth's gravity revealed in unprecedented detail at: http://www.esa.int/esaCP/SEM1AK6UPLG_index_0.html
The road to choosing custom projections is not paved with sundrops and lilies. It is time to start learning the nuts and bolts of coordinate systems.
Minute Markers:
-0:27- Geodesy, the geoid.
-1:10- Ellipsoid, geographic coordinate system.
-2:09- Can't effectively measure with ellipsoid.
-3:21- Planar coordinate system.
-3:49- Geodetic datums.
-5:41- Projections.
-6:47- REMEMBER this, degrees vs. linear units.
-7:10- Three types of projections.
-7:32- Recap.
All images included are in the public domain, though the geoid image was originally created here I believe (correct me if I'm wrong):

The geoid is essentially a map of where the Earth's gravity is all equal: if you flooded the entire planet with water, this is the shape it would if gravity were the only thing shaping this global ocean's surface.This shape has been measured to high accuracy using the ESA's GOCE satellite.

GeoidEvery schoolchild knows the answer to the question - which mountain is the highest in the world? Surely it is Mount Everest, or Chomolungma (8848 metres), which is its more modern name. This is true if we count from above sea level. And what if we count from the centre of the Earth? Then the highest point is the Chimborazo volcano located in Ecuador, not far from the equator. Its height is only 6384 metres above the sea level. But this mountain is situated in the right place. The key to the explanation of this surprising fact is in the Earth's shape. Due to revolution the Earth has the shape of a ball flattened at the poles, a so called ellipsoid of revolution. So, the Earth's equatorial radius is 22 kilometres longer than the polar radius. In truth, the Earth's shape is a more complex figure, called geoid by scientists due to existence of the continents, tides and other things like these. A geoid is a figure which reflects the shape of the gravity force potential on the Earth. Geoid is an important notion in geodesy. A geoid is defined as equipotential surface of the terrestrial gravitational field which almost coincides with mean ocean water level and is conventionally prolonged under the continents. In fact scientists are not really interested in the form of the Earth surface. It's much more important for them to know the 'form' of terrestrial attraction. To know how it changes at different places of our planet and thereby see through the earth. To see iron ore, minerals, petroleum. And how about the rockets and satellites speeding on the waves of terrestrial attraction? To calculate their orbits we do need to know gravity sailing directions. And satellites give as good as they get. Studying their movement we learn more precisely how our planet attracts them and how it looks like. Our idea of the Earth's shape keeps changing, but the name stays the same: geoid stays geoid.

In this Tech Talk we show you the procedure for uploading a Geoid Model to your Trimble data collector using the Trimble Business Center office software. Geoid Models are extremely important when working with an RTK survey. It is also important to know what Geoid Model to use in various scenarios in the field, as well as knowing when to use the WGS84 or Local interpolations of the models.

Geoid
The geoid is the shape that the surface of the oceans would take under the influence of Earth's gravitation and rotation alone, in the absence of other influences such as winds and tides. This surface is extended through the continents (such as with very narrow hypothetical canals). All points on the geoid have the same gravity potential energy (the sum of gravitational potential energy and centrifugal potential energy). The force of gravity acts everywhere perpendicular to the geoid, meaning that plumb lines point perpendicular and water levels parallel to the geoid.
Specifically, the geoid is the equipotential surface that would coincide with the mean ocean surface of the Earth if the oceans and atmosphere were in equilibrium, at rest relative to the rotating Earth, and extended through the continents (such as with very narrow canals). According to Gauss, who first described it, it is the "mathematical figure of the Earth", a smooth but highly irregular surface whose shape results from the uneven distribution of mass within and on the surface of the Earth. It does not correspond to the actual surface of the Earth's crust, but to a surface which can only be known through extensive gravitational measurements and calculations. Despite being an important concept for almost two hundred years in the history of geodesy and geophysics, it has only been defined to high precision since advances in satellite geodesy in the late 20th century. It is often described as the true physical figure of the Earth, in contrast to the idealized geometrical figure of a reference ellipsoid.

GeoidEvery schoolchild knows the answer to the question - which mountain is the highest in the world? Surely it is Mount Everest, or Chomolungma (8848 metres), which is its more modern name. This is true if we count from above sea level. And what if we count from the centre of the Earth? Then the highest point is the Chimborazo volcano located in Ecuador, not far from the equator. Its height is only 6384 metres above the sea level. But this mountain is situated in the right place. The key to the explanation of this surprising fact is in the Earth's shape. Due to revolution the Earth has the shape of a ball flattened at the poles, a so called ellipsoid of revolution. So, the Earth's equatorial radius is 22 kilometres longer than the polar radius. In truth, the Earth's shape is a more complex figure, called geoid by scientists due to existence of the continents, tides and other things like these. A geoid is a figure which reflects the shape of the gravity force potential on the Earth. Geoid is an important notion in geodesy. A geoid is defined as equipotential surface of the terrestrial gravitational field which almost coincides with mean ocean water level and is conventionally prolonged under the continents. In fact scientists are not really interested in the form of the Earth surface. It's much more important for them to know the 'form' of terrestrial attraction. To know how it changes at different places of our planet and thereby see through the earth. To see iron ore, minerals, petroleum. And how about the rockets and satellites speeding on the waves of terrestrial attraction? To calculate their orbits we do need to know gravity sailing directions. And satellites give as good as they get. Studying their movement we learn more precisely how our planet attracts them and how it looks like. Our idea of the Earth's shape keeps changing, but the name stays the same: geoid stays geoid.

And how about the rockets and satellites speeding on the waves of terrestrial attraction? To calculate their orbits we do need to know gravity sailing directions. And satellites give as good as they get. Studying their movement we learn more precisely how our planet attracts them and how it looks like. Our idea of the Earth's shape keeps changing, but the name stays the same: geoid stays geoid.

Madonna
Lover come and set me free from my restrain
Tear the rags away they bind me
Stare me down and cut me deeply to the bone
Give me every tooth and blind me
You are Madonna, you Lady Divine
You are part Mother Theresa and a valentine
Some man's pariah and a slippery slope
But to me you are the fire and I fly to my hope
Mother teaching me now lessons from the past
In faded photo albums lying open on the floor
She heals me with a Nikon camera captured laugh
And with a wink she sets me free forever more
So consume me now and burn me to the marrow
Heat me up like the world can never do
Tear my heart out from my body if you have to and
Then swallow me to prove that I am you
You are Madonna, you are lady divine
You are part Mother Theresa and a valentine
Some man's pariah and a slippery slope
But to me you are the fire and I fly to my...
You are Madonna
You're lady divine
You are part Mother Theresa and a valentine

I'll fly
I will take these wings and fly away
