bitmapped graphics

The common representation of a digital image as a matrix (rows and columns) of picture elements (see bitmap). All CRT, LCD, OLED and plasma screens are bitmapped-graphics displays. Images acquired by digital cameras, digital camcorders and scanners are bitmaps. Also known as "raster graphics," images created in paint programs are bitmapped. There are many bitmapped formats, including JPEG, GIF, BMP and TIFF (see graphics formats). Bitmapped graphics and "vector graphics" are the two fundamental architectures of digital images (see graphics for details).

Other than that, more basemaps and raster format are supported, like TIFF and Google Maps.
All the thematic layers were converted to raster format with cell size of30 x 30 m resolution and thus the correlation oflandslide and triggering factors were evaluated.
Data about height and depth of an object were used to convert height objects to a raster format. During the conversion of a vector into a raster it happens that the individual objects are converted into a set of pixels with a value of an attribute, according to which the conversion is realized (e.g., hgt, which is a height of an object).
Once we input all of the points with their corresponding depth values, Arc-GIS Spatial Analyst was used to convert the shapefile from vector format to raster format. The raster file was then imported into ArcScene in order to develop a three dimensional model of the buried karst features from the GPR data.
Checking anti-alias helps smooth the lines in transition from vector to raster format and constrain proportions keeps the width and height linked so the project dimensions do not get distorted.
The geo-referenced maps can be imported from almost any source in either vector or raster format and zoomed in and out.
Softcopy Imagery Intelligence (IMINT) products in a raster format could be embedded or encoded with improving accurate geographic metadata and shared with multiple users across an electronic medium.
In order to display the data in a raster format, each value, or a range of values, is assigned a specific color.
This is another raster format. TIFF (CMYK) cannot be opened by a browser, so a supplemental utility is needed in order to open CMYK files.
The LULC was derived from TM images in a raster format. By overlaying LULC with soil thickness, texture, family, subgroup, or EI layer, we obtained the final results in a raster format.
