Latitude in Snyder (page 15): For the "normal" Mercator projection (on the ellipsoid) this function defines the spacing of the parallels: if the length of the equator on the projection is (units of length or pixels) then the distance, , of a parallel of latitude from the equator is The isometric latitude is closely related to the conformal latitude : The formulae in the previous sections give the auxiliary latitude in terms of the geodetic latitude. The expressions for the geocentric and parametric latitudes may be inverted directly but this is impossible in the four remaining cases: the rectifying, authalic, conformal,
Google Latitude information was then used to display statistics such as "Time At Work", "Time Spent At Home" and "Time Spent Out". Google Latitude Google Latitude was a location-aware feature of Google Maps, developed by Google as a successor to its earlier SMS-based service Dodgeball. Latitude allowed a mobile phone user to allow certain people to view their current location. Via their own Google Account, the user's cell phone location was mapped on Google Maps. The user could control the accuracy and details of what each of the other users can see — an exact location could be allowed, or it could
