2. Introduction
• Vector Data. A representation of the world using points, lines, and
polygons.
• Vector models are useful for storing data that has discrete boundaries, such
as country borders, land parcels, and streets.

3. Vector Data file formats list in GIS
• n GIS, we require some data formats to express the geographical features,
which mainly are of two types Raster and Vector data formats.
•
• Vector considers the geographical features as geometrical shape and express
them by different types of geometry.

4. • Points:
• Zero-dimensional points data is most commonly used to represent
nonadjacent features and geographical features that can be expressed by
single point and to represent discrete data points. Points have zero
dimensions, therefore you can measure neither length or area with this
dataset.

5. Contd…..
• Examples:
• Schools, points of interest, wells, peaks. Points features are also used to
represent areas when displayed at a small scale and abstract points. For
instance, point locations could represent city locations or place names.
