Satellite remote sensing is an important source of spatial data. For this, satellites use different sensor packages to passively measure reflectance of parts of the electromagnetic spectrum or radio waves that were emitted by an active sensor such as radar. Remote sensing collects raster data that can be further processed using different wavelength bands to identify objects and classes of interest, e.g. land cover.
Describe and explain standard spatial (and non-spatial) data input techniques (non RS) including the management of the data collection process (level 1 and 2).
