[remote sensing] Landsat is NASA/USGS mission spanning more than three decades and eight satellites with space-borne remote sensing capabilities of scanning land resources.
[coordinate system] Latitudes are spherical coordinates of Earth locations that vary in North-South directions. Lines of latitude are angles on the Earth’s surface which ranges from 0° at the Equator to 90° (North or South) at the poles.
A logical set of thematic data described and stored in a map library. Layers act as digital transparencies that can be laid atop one another for viewing or spatial analysis.
|6||Light Detection and Ranging (LiDAR)||
[remote sensing] LiDAR uses laser pulse measurements to identify heights, depths and other properties of features on the Earth’s surface. Example outputs for LiDAR are digital elevation models, light intensity and digital surface models.
Lines represent geographic features too narrow to be displayed as an area at a given scale, such as contours, street centerlines, or streams.
[coordinate system] Longitudes are coordinate on Earth that vary in east-west directions. They are usually expressed in degrees ranging from 0° to +180° east and −180° west. The prime meridian marks the 0° longitude and passes through the Royal Observatory in Greenwich, England.
