Spatial data are of two types according to the storing technique, namely, raster data and vector data.
What are the two functions of GIS?
Functions of GIS include: data entry, data display, data management, information retrieval and analysis. A more comprehensive and easy way to define GIS is the one that looks at the disposition, in layers (Figure 1), of its data sets.
What are two examples of GIS?
For example, using GIS, a single map could include sites that produce pollution, such as factories, and sites that are sensitive to pollution, such as wetlands and rivers. Such a map would help people determine where water supplies are most at risk. GIS applications include both hardware and software systems.

What are the five components of GIS?
A GIS can be divided into five components: People, Data, Hardware, Software, and Procedures. All of these components need to be in balance for the system to be successful.
What are the components of a GIS system?
The most important component of a GIS is the data, geographic and related tabular data (spatial and non-spatial data). GIS will integrate spatial data with other data resources and use DBMS to organise and maintain the spatial data.
What are the elements of a GIS?
GIS includes the following elements: Software, hardware, and data Relative locations of features in x, y, and z coordinates (longitude, latitude, and elevation) Relationships between features
What are the basics of GIS?
A Dictionary of Geography defines a Geographic Information System (GIS) as an integrated, spatial, data-handling programmes which will collect, store, and retrieve spatial data from the real world. They are powerful tools in decision-making, as they can incorporate coordinated data.
