<P> Advances in photochemical technology, such as the lithographic and photochemical processes, have allowed for the creation of maps that have fine details, do not distort in shape and resist moisture and wear . This also eliminated the need for engraving which further shortened the time it takes to make and reproduce maps . </P> <P> In the mid-to - late 20th century, advances in electronic technology have led to further revolution in cartography . Specifically computer hardware devices such as computer screens, plotters, printers, scanners (remote and document) and analytic stereo plotters along with visualization, image processing, spatial analysis and database software, have democratized and greatly expanded the making of maps, particularly with their ability to produce maps that show slightly different features, without engraving a new printing plate . See also digital raster graphic and History of web mapping . </P> <P> Aerial photography and satellite imagery have provided high - accuracy, high - throughput methods for mapping physical features over large areas, such as coastlines, roads, buildings, and topography . </P>
