Raster or gridded data may be the result of a gridding procedure. A single numeric value is then stored for each pixel. For most images, this value is a visible color, but other measurements are possible, even numeric codes for qualitative categories. Each raster grid has a specified pixel format, the data type for each
ESRI's ArcGIS 8.3+ has the capability of rubbersheeting vector data, and ArcMap 9.2+ may also rubber-sheet raster layers.; Autodesk's AutoCAD Map 3D [1] and AutoCAD Civil 3D (which includes most of AutoCAD Map 3D's functionality) allows a user to rubbersheet vector data, and Autodesk's Raster Design (an add-in product for AutoCAD-based products) allows a user to rubbersheet raster data.
Raster graphic image. In computer graphics, rasterisation (British English) or rasterization (American English) is the task of taking an image described in a vector graphics format (shapes) and converting it into a raster image (a series of pixels, dots or lines, which, when displayed together, create the image which was represented via shapes).
The latest version of the software, Volo View 3, worked with the following file formats: AutoCAD 2004, DWG and DXF; Design Web Format (DWF 6); Autodesk Inventor 7 IPT, IAM, and IDW and raster files. The functionality of this product is largely replaced by Autodesk DWF Composer (versions 1 and 2) later replaced by the free Autodesk Design Review .
Raster data is computationally less expensive to render than vector graphics; Combining values and writing custom formulas for combining values from different layers are much easier using raster data. There are transparency and aliasing problems when overlaying multiple stacked pieces of raster images.
Raster may refer to: Raster graphics, graphical techniques using arrays of pixel values; Raster graphics editor, a computer program; Raster scan, the pattern of image readout, transmission, storage, and reconstruction in television and computer images; Rasterisation, or rasterization, conversion of a vector image to a raster image

CAD software for mechanical design uses either vector-based graphics to depict the objects of traditional drafting, or may also produce raster graphics showing the overall appearance of designed objects. However, it involves more than just shapes.
