Geographic
Information System (GIS)
GIS is a method of
taking hardware, software, data, and people then combining them to look at
geographical information and making it easier to find solutions for questions.
These sources merge cartography, statistical analysis, and database technology
to present many types of geographical data. Most geographic information systems
are custom-designed.
Weaknesses and
Challenges
One of the main weaknesses of GIS is that it can be
highly time consuming. The information provided is also only as good as the
data that it's sourcing from. If there are issues with compatibility or data
collection, this can also cause problems with data output.
