comes from the two different fundamental GIS models: vector and raster. Each of these models has its own advantages and disadvantages. The vector model uses points and line segments to identify locations on the earth while the raster model uses a series of cells to represent locations on the earth. The figure represents vector (left)

Compact data structure – Need less space for storing data. 2. Accurate Graphic output. 3. Since most information, e.g. printed version maps, is in vector form no data conversion is required. 4.

Vector models are useful for storing data that has discrete boundaries, such as country borders, land parcels, and streets. Secondly, what is raster and vector data in GIS? Raster and vector are two very different but common data formats used to store geospatial data. As such, vector data tend to define centers and edges of features.

Most advanced GIS software can handle both models and even convert data between the two. Slide 5 The real world can be described using two conceptually different models: 1. The ArcInfo coverage GIS format is a georelational data model that stores vector data. It has no extension, just a set of folders. Coverages use feature classes, stored as points, arcs, polygons or annotation. Feature attributes are stored in the ArcInfo Coverage’s.adf or INFOb files.

It has no extension, just a set of folders. Coverages use feature classes, stored as points, arcs, polygons or annotation. Feature attributes are stored in the ArcInfo Coverage’s.adf or INFOb files. In contrast to the raster data model is the vector data model. In this model, space is not quantized into discrete grid cells like the raster model. Vector data models use points and their associated X, Y coordinate pairs to represent the vertices of spatial features, much as if they were being drawn on a map by hand (Aronoff 1989).Aronoff, S Digitising is the process of creating digital vector data by drawing it in a GIS application.

The GRASS GIS vector management model allows to link map objects to database management systems (DBMS). In this short section, we try to give an overview on how GRASS matches map features and attributes.

The vector model uses points and line segments to identify locations on the earth while the raster model uses a series of cells to represent locations on the earth. The figure represents vector (left) Conclusion Geographic Information System is a computer system for capturing, storing, checking, and displaying data related to positions on Earth’s surface. A data model in GIS is a mathematical construct for representing geographic objects or surfaces as data. The two basic data models of GIS are Raster and Vector.
