Abstract

Graphics such as maps, aerial photos and satellite images have become an integral part of the web. One of the reasons for this is reducing the cost of distribution and presentation, because putting color graphics on the web is much cheaper than color printing on paper. When we consider the extra shipping and distribution costs for print products, we will realize that distributing maps and images over the Internet is cost-effective. However, printing maps has advantages that cannot be ignored, including very suitable print resolution (the high resolution print has a resolution of 1200 to 3400 dots per inch or 472 to 1339 dots per centimeter). On the other hand, computer screen can only have a precision of 65 to 120 dpi (25.6 to 47.2 dots per centimeter). Computer screen has limitations in terms of screen dimensions: the standard screen size ranges from 14 inches to 21 inches, while maps, photos and prints can be made at much larger cuts.
