- GIS usually consists of software and hardware that aid in mapping
urban centres, hydrological distribution, road networks, and large amounts
of data that relate to specific geographical features.
- It is an application that compares tabular data and illustrates spatial
relationships. It permits selective analysis and the end results are
usually illustrated as ‘maps’. A GIS scores over a conventional
‘static’ map as it lets users query a database and visualise
answers interactively.
- It is a planning tool that can be combined with modelling applications
to determine ‘what if’ scenarios.
- It helps organisations get accurate data that directly translates
into better decision-making. A GIS, for instance, can help in monitoring
animal health and controlling disease on a dairy farm.
- Accuracy depends upon data. It is critical that users verify metadata
to determine data accuracy and ensure that it is suitable for their
applications.
