Raster IS a type of image data another type is VECTOR.
Raster deals with picture elements (pixels) these are discrete bits of the picture , small dots or swuares that together make up the entire image).
Vectors deal with mathematical expressions for lines and areas. You can zoom in invinitely into a vector image and neve get blocks or jaggged edges which appear in raster images.

What is VECTOR and raster?
RasterIn Geographic Information Systems, a grid square Raster data are spatial data expressed as a matrix of cells, with spatial order indicated in the ordering of the cells. A raster map is a map stored as a regular array of cells; a raster scanner records an image by breaking it into pixels. Raster to vector conversion consists of changing an image made up of cells (rasters) into one made up of lines and polygons.Vector data provide for high precision in representing the location of features. vector data can be used to define the location of a point, a line, and an area. A point is represented by a simple pair of coordinates.- Vector Data model uses objects to represent and organize spatial features.- The geometry (spatial data) of a feature is stored as an attribute along with other attributes in a record.

What is difference between cryptography and image steganography?
main diff is cryptography in change the code format of original data & image stenography hide the data behind other file not change the data code this is main diff b/w image stenography & cryptography.
What is vectorization in GIS?
Vectorization in GIS is the process of converting raster data (such as satellite imagery) into vector format (points, lines, or polygons) by identifying and representing distinct features or objects within the image. This allows for more precise analysis, editing, and storage of geographic information.
What is raster data?
Commonly used in GIS systems, it is basically pixelated data.
What is difference between object space and image space in graphics?
Object space helps you to keep the data in the right place. Image space is more flexible and easier to use.
What is the difference between magnification resolution?
magnification is the number of times an object is enlarged, while resolution is the amount of data (detail) in an image.
What is the difference between OLAP and data mining?
difference between Data Mining and OLAP
What is difference between a raster and a vector display unit?
Raster images are made up of pixels, Vector images are made up of paths. Raster images (sometimes called bitmap images) are made up of a grid of pixels, each of which can be a different colour.Vector images, on the other hand, rely upon mathematical relationships between points in order to make up paths, which when all combined, make up a full image.Bitmaps are better for photographs or images with complex shading. Vectors are better typefaces and illustrations. Vectors also scale much better than bitmaps.
What is the difference between allocation and search data structure?
difference between serch data structure and allocation data structure
What are the environmental settings specific to raster data and why are they important?
I am assuming this is for geography??? please try to be more specific, I know quite a bit about GIS and raster data, but i can not makes heads or tails of this question
What is the difference between data communication and data communication information2010to2013?
The scope of work and the educational requirements are the difference between data communication and data communication information.
