What are the different types of GIS data?

There are two main types of GIS data: vector data and raster data. Vector data represents geographic features with points, lines, and polygons, while raster data represents information in a grid format, like satellite images.

Can you explain vector data in more detail?

Sure! Vector data is made up of discrete geometric shapes. Points represent specific locations, lines represent linear features like roads, and polygons represent areas like lakes or land parcels.

What about raster data? How is it used?

Raster data is used for continuous data representation, such as elevation or temperature. Each cell in the grid has a value, making it ideal for analyzing spatial patterns and changes over time.

Are there any other types of GIS data?

Yes, there are also other types like attribute data, which provides information about the features, and metadata, which describes the data itself.
