Abstract
Included the development of scientific and technological knowledge maps (Cartography), in terms of business fundamentals and tools, Including entry of computer and software that are used in dealing with the production of maps and field survey, It entered the GIS software, has provided great facilities for their high storage, And flexibility to deal with various forms of data types, and their ability to restructure data and devise new ones. That the different forms of map data of equal height, the imposition of a diversity of ways of dealing with them to get the best results to be achieved, there are data of coordinates, altitude, and tables that are in or are dropped directly by the global positioning devices (GPS), As there are more data (Raster Data), represented by paper maps that have been converted to digital form (Digital) by a digital scanner,There are files and digital elevation models (Digital Elevation Model), which are images of a satellite cells not only give the coordinates of each cell, but also give the value of the exact height of the surface of the earth. Maps to represent the height of equal use different ways is the most common fonts, and is also used deception in the spatial representation of the rise, One of the most important maps of equal height are not limited to the representation of the surface of the earth only, but can be used to represent various natural phenomena and human on the end either.
