2. Name at least three technologies that have led to the advancement of
geographic techniques.

- GISs,

- Geographic visualization

- Spatial statistics

Explanation:

The three technologies that have contributed to the evolution of geographic techniques are GIS(Geographic Information System), the technique of geographic visualization, and spatial statistics. GIS has made it easier to 'associate apparently unassociated data and allows individuals to comprehend the spatial relationships more effectively' by showing different data related to different locations on the Earth that are captured and stored by the computer system.
