Georeferencing

All data used in a GIS needs to be defined by a coordinate system and data used for a particular application must be georeferenced to the same coordinate system.

Ground truthing is generally used to locate remotely sensed data.

For cadastral data sets parcel boundaries, locations of infrastructure and utilities features can be surveyed accurately using laser theodolites.
Socio-economic and demographic information can be linked to cartographic zones with a particular spatial reference.
Information from market research can be linked to post-codes to spatially locate the data.
Natural resource information is normally recorded in terms of latitude and longitude.

List the reasons why it is important to georeference the data you use in a GIS and identify how GPS can help.
