Oracle - Difference between Vector and Raster data. posted by
Difference between Vector and Raster data.
While vector features use geometry to represent the real world, raster data
takes a different approach. Raster’s are made up of a matrix of pixels each
containing a value that represents the conditions for the area covered by that
Vector data is used for representing homogeneous data as they aren't very good
at representing features that are not homogeneous all over. But Raster data is
used for representing heterogeneous data.
Raster objects are made up of pixels and are considered resolution dependent
because they contain a fixed number of pixels that are used to create the
image. However vector data does not use pixels.
A vector data is based on points, lines, and areas defined by drawing boundaries
around features and labeling or attributing them. While rapter data is based on
images and polygon.
