Both these models are common in GIS and the difference between them is in the level of structure and organisation of the data. What GIS is How GIS works What GIS can do GIS data types Spatial data Tabular data Modifying views of data Managing data sources Thorough knowledge of these topics are necessary before undertaking any analytical tasks. In this section basic vector analysis will be discussed.

According with the characteristics of this data model, geographic objects are explicitly represented and, within the spatial characteristics, the thematic aspects are associated. There are different ways of organising this double data base (spatial and thematic). Vector Data Model is an object based approach to the representation of real world features. This data model is best suited to represent discreet objects. In this method the entire earth surface feature including man-made and natural can be represented by only three entities in GIS. Vector data is not made up of a grid of pixels. Instead, vector graphics are comprised of vertices and paths.

Raster vs vector. Both types of data are very useful, but there are important differences. 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. In this video, I have clearly shown the steps required to Convert Raster File into Vector File in Arc GIS software.#SharingisCaring#PleaseSubscribeCheck thi Vector Map (VMap) Vector Map (VMAP), is a vector-based collection of GIS data covering the world at various detail levels.

This is a commonly used format that can be directly used in Arc-anything, DIVA-GIS, and many other programs. It can be imported to most other GIS programs. A vector based GIS is defined by the vectorial representation of its geographic data.
