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).

The digital display on the computer remains crisp and clear as the user zooms in to look at the map in more detail--unlike Compressed ARC Digitized Raster Graphics (CADRG).
One map display format, ARC Digitized Raster Graphics (ADRG), provided a clear view of the scanned map in computer displays, but file sizes were so large that few maps could be loaded on a single CD.
Diversity of data content is not tied exclusively to the existence of different data formats (e.g., raster graphics, ASCII texts, GIS) and metadata schemes (e.g., the Text Encoding Initiative's [TEI] Header, the VRA core, the metadata standards recommended by the Federal Geographic Data Committee--FGDC) but to the fact that there are few common implementations of any single format or scheme.
