@tmcw: hi
an educational project about maps & the earth
community-written for a wide audience
conceptual, not technical
#1: GIS © education is branded
2013 + 70 = ©2083
...but colleges use ebooks
#3: Criticism Creation
we don't learn what to do by being told what not to do
corollary: complaining is more popular than explaining
#4: GIS Wikipedia is an Embarrassment
On November 5, 2007 at a ceremony which took place during the Global Forum 2007 at the Fondazione Giorgio Cini in Venice, Italy, the CTA-supported project Participatory 3D Modelling (P3DM) for Resource Use, Development Planning and Safeguarding Intangible Cultural Heritage in Fiji[4] was granted the World Summit Award 2007 in the category e-culture. The product, based on the use of P3DM, has been considered as one of the 40 best practice examples of quality e-Content in the world[5]. The product has been delivered by the following organizations: Fiji Locally-Managed Marine Area (FLMMA) Network, WWF South Pacific Programme, Native Lands Trust Board, Secretariat of the Pacific Community, National Trust of Fiji, Lomaiviti Provincial Council and the Technical Centre for Agricultural and Rural Cooperation ACP-EU (CTA).

Because the Earth is a spinning object and its components can change shape, it bulges at the middle. Instead of a sphere, it’s more similar in shape to a oblate spheroid. If you look even closer, that isn’t entirely true either - the Earth is covered in elevation differences like mountains and valleys, and even manmade changes like cities.
For day-to-day work, we use different estimates of this shape: standards like WGS84 define precise values for the length of both of the Earth’s axes, so we can estimate for a reference ellipsoid rather than a sphere. Local measurements and science that relies on precise surface values can also use geoid models, which are three-dimensional calculations of theoretical ocean heights.
This branch of Earth sciences, called geodesy, is a continuing project since our ability to model and measure the Earth moves quickly and the Earth itself changes in shape.
