Vector models are useful for storing data that has discrete boundaries such as country borders land parcels and streets.

Raster and vector data models. Easily make a. Vector data is not made up of a grid. In general the vector data model is used to represent the former and the raster data model to represent the latter. Raster and vector refer to a particular data model.

A data structure refers to a particular implementation of either the raster or vector model. Vectors models are points lines and polygons. As well a typical gis process involves moving back and forth between the two models. Data models a representation of the world as a surface divided into a regular grid of cells.

When should we use raster and when should we use vector. Since most information eg. 1082014 2 data structures and data models. Exact geographic location of data is maintained.

But what is the difference between raster and vector data. Raster and vector refer to a particular data model. 9302019 2 data structures and data models. The two primary types of spatial data are vector and raster data in gis.

Printed version maps is in vector form no data conversion is required. A data structure refers to a particular implementation of either the raster or vector model. However the lines od separation are sometimes crossed.
