Abstract Cartography is a technique fundamentally concerned with reducing the spatial characteristics of a large area-a portion or all of tile earth or another celestial body-and putting it in a form that makes it observable. Just as spoken and written language allow people to communicate beyond the restriction of having to point to everything. A map allows us to extend the normal range of visions to speak, and makes it possible for us to see the boarder spatial relations that exist over large areas. Cartography can also be defined as: The art, science and technology of making maps, together with their study as scientific document and works of alt. In the board sense cartography now includes ally activity in which the preparation and use of maps is a matter of basic interest. This includes teaching tile skills of map use, studying the history of cartography, maintaining map collections, and designing and constructing maps, charts, plans, and atlases. Although each area i.nvolves highly specialized activities and often requires particular training, they all deal with maps, and it is the special character of the map as the central unique mental object that joins those who work with them. Recently, all cartographic procedures can be canied out by computer. One of the most important applications of computer in the surveying fields the uses of computer-aided cartography for the production of different types of geographic, topographic and other maps. The Utilization of computer in maps making led to the production of digital maps with wide range of applications. One of the computer aided cartography applications is the production of photo-maps derived from either conventional or digital photos. The objective of tills research project is to study the utilization of computer in aiding the production of maps and compare tlus process with the procedure of producing line maps in the conventional and digital forms. This comparison includes study about the effect of levels presentation on accuracy in conventional and digital forms. In order to achieve the previously stated objectives, this thesis presents the fundamentals of cartographic techniques as well as the theoretical background of different types of maps, sources of map data, and methods of map compilation such as: ground surveying, aerial surveying and satellite methods. This study, also, covered the details of cartographic representation such as: cartographic symbols, methods of map representation for relief, physical features, artificial features, lettering and generalization.This study was practically applied onto two different networks. In each network the heights of points as extracted from both digital andconventional methods were compared and commented. The results of comparisons were addressed and tabulated. Finally, depending on the practical companson, some recommendations concerning maps data and associated map compilation process were presented inorder to meet the required accuracy of such map. |
