Related QuestionsMARIS: Frequently Asked Questionsabstraction of the real world where spatial data is expressed as a matrix of cells or pixels, with spatial position implicit in the ordering of the pixels. With the raster data model, spatial data is not continuous but divided into discrete units. This makes raster data particularly suitable for certain types of spatial operation.Related Questions

Related QuestionsHow is the raster data stored in the nui file?
Welcome to PIXIAThere are numerous proprietary patent-pending techniques used to store the raster data in the nui file. These are, of course, highly confidential. Additionally, the raster data is also stored with pyramid levels. Pyramid levels (a.k.a. RRRD's – Reduced Resolution Datasets) store numerous discrete resolutions of the original file in the same file.
Related QuestionsHow do I know if my file is a vector file or a raster (bitmap) file?
Visigraph Corporation - Signs - Banners - Decals - Graphic D...There are a couple of ways. The best and quickest way, if you can open the file, is to zoom in on the edge of a letter. If you see lots of little squares (pixels or bitmaps), you have a raster file. If it looks clean like a line that you draw with a ballpoint pin, you more than likely have a vector file. The second way is to look at the file extension.
Related QuestionsHow come some vector files are bigger than the raster image file? Should this happen?
Frequent Asked QuestionsThe raster image size is based upon the resolution (dpi) and the physical size of the image. The vector file size is based upon the number of vectors required to represent the raster file: Say the raster image is comprised of curved lines and the vectorizing software mode selected only creates vector files comprised of straight lines, arcs and circles. In this mode the resultant vectors of the curves have to be represented by an arc, or a line or a circle.
Related QuestionsQuestion 11: Where is the Raster Manager Help file located?
SELECTservices | 6195 - Raster Manager FAQAnswer: In the 2004 Edition, there is a special setting specifically designed to enhance opening speed when attaching an image via a network drive. To enable this feature, you must create the following configuration variable: MS_RASTER_LOADMODE Set this variable to "3" in order to speed up the attach/display operation for any image accessed through a network drive. A cache file will be created on the local drive in the folder pointed to by the Windows Environment variable TMP or TEMP.

Related QuestionsWhat is raster, vector art?
Midwest Conference Service - Frequently Asked QuestionsThese terms are used to classify the type of data a graphics file contains. Raster files (also called bitmapped files) contain graphics information described as pixels, such as photographic images. Vector files contain data described as mathematical equations and are typically used to store line art and CAD information. Vector files have the additional capability of being scaleable meaning that ordinarily, no image editing is necessary.
Related QuestionsWhat is a Raster Image?
Promotional Products, Promotional Items Vancouver BC Canada:...A raster image is a scanned or placed image that can be in color, gray scale, or black and white, whose clarity is dependent upon the resolution. The resolution of a raster graphic is the number of dots, pixels or lines per inch of graphic. Therefore, the higher the resolution, the crisper the image.

What is the Raster Profile?
Spatial Data Transfer Standard (SDTS) FAQThe raster profile is titled SDTS Raster Profile and Extensions (SRPE). It will be approved by FGDC in 1998 as Part 5 of the SDTS. The SRPE applies to two-dimensional raster grid or image data that may optionally be georeferenced. The raster profile supports the transfer and archive of image data, digital terrain models, gridded GIS layers, and other gridded data. The extensions allow alternate file formats to be used to encode image data.

Related QuestionsWhat's the difference between raster and vector files?
Frequent Asked QuestionsA raster image is roughly equivalent to a newspaper photograph. If you look closely you see that it is made up of lots of small dots. The density of these dots is referred to by resolution, measured in dots per inch (stated as 'dpi'). Raster files are stored in many file formats, TIFF is a common example. Vectors are used to describe specific objects defining their size, position and geometry. The image seen on screen in a CAD application is only a visual representation of the vector file.
