  1. Raster vs. Vector Lecture 5

  2. Raster and Vector Reality  • One of the sharpest distinctions among GIS is the way that location is represented in a database, as either a raster or vector position.   These materials were developed by Kenneth E. Foote and Donald J. Huebner, Department of Geography, University of Texas at Austin, 1996.

  3. Raster vs. Vector "Raster is vaster, Vector is more correcter"

  4. The Raster View of the World • A raster based system displays, locates, and stores graphical data by using a matrix or grid of cells. • Each cell has an (x,y) location and a (z) value which stores attribute data about that location.

  5. The Vector View of the World • A vector based system displays graphical data as points, lines or curves, or areas with attributes.

  6. Advantages and Disadvantages These materials were developed by Kenneth E. Foote and Donald J. Huebner, Department of Geography, University of Texas at Austin, 1996.

  7. Raster data can be converted to Vector and vice versa Note: Converting from one system to the other can introduce error. These materials were developed by Kenneth E. Foote and Donald J. Huebner, Department of Geography, University of Texas at Austin, 1996.
