Distance to Nearest Coastline: 0.04-Degree Grid: Ocean
A global data set of ocean distances from the nearest coastline. NASA's Ocean Biology Processing Group (OBPG) generated this data set using the Generic Mapping Tools (GMT)... -
Tropic of Capricorn
The Tropic of Capricorn lies at 23d 26' 22" (23.4394 degrees) south of the Equator and marks the most southerly latitude at which the sun can appear directly overhead at noon.... -
Distance to Nearest Coastline: 0.04-Degree Grid: Land

ETOPO5 Global Surface Relief
ETOPO5 is a 5 arc-minute global relief model of Earth's surface that integrates land topography and ocean bathymetry. It was built from numerous global and regional data sets.... -
Prime Meridian
The Prime Meridian is the meridian (line of longitude) at which the longitude is defined to be 0 degrees. The Prime Meridian and its opposite, the Antimeridian (at +/-180... -
Distance to Nearest Coastline: 0.04-Degree Grid
A global data set of distances from the nearest coastline. Negative distances represent locations over land (including land-locked bodies of water), while positive distances... -
Tropic of Cancer
The Tropic of Cancer lies at 23d 26' 22" (23.4394 degrees) north of the Equator and marks the most northerly latitude at which the sun can appear directly overhead at noon. This... -
