Vector features are group into layers and features in a specific layer have the same geometry type. For example, if a layer contains a Polygons feature, then GIS application will only allow a user to create a new polygon feature in the same layer. Each of the vector features is stored in a database along with their attributes. Vector data are composed of discrete geometric locations (x, y values) known as vertices that define the shape of the spatial object. Learn how to work with spatial data in vector format in Python, including how to import, manipulate and map shapefile data. You will also learn how to reproject vector data into different coordinate reference Raster is faster but vector is corrector .

There are a large number of options available in QGIS to apply different types of symbology to the underlying data. Vector data import and export The module offers a common interface for many different vector formats. Additionally, it offers options such as on-the-fly creation of new locations or extension of the default region to match the extent of the imported vector map..

Shapefiles combine non-topological data with associated attributes. To breakdown what that means, let’s return to our original definition of GIS: the intersection of data and location.
