The mercator projection is a commonly used projection on computer maps because it has perpendicular latitude and longitude lines (forming rectangles). It is formed by projecting the globe onto a cylinder A variant of the was adopted by Google maps, which helped establish it as the informal standard for web-based maps (although Google maps now also uses a globe view, instead of a map projection when zooming out to a very wide view).

The initial push will be to the regularly updated 20 services that are considered SGID framework data: roads, address points, parcels, boundaries etc. As we roll these services out as Web Mercator, we are also looking at possibly creating some web maps that will allow users to more easily consume the most popular map layers with large feature counts.
Ocean Forecast: Output from an ocean model to predict the future state of the ocean for periods from 1 day to 14 days ahead. Ocean Forecast products are updated weekly or daily, depending on the ocean model concerned.
Ocean Analysis: Output from an ocean model giving the best possible estimate of the recent and present ocean state. These results are aggregated in time, making up time series that are updated and incremented with the latest results either daily or weekly, depending on the ocean model concerned. These analyses represent ocean states that are almost simultaneous with the present time.
