Topographic MapsoTopographic maps are detailed, accurate graphic representations of features that appearon the Earth’s surfaceMap DefinitionoMaps are graphic representations of the cultural and physical environment and the output from a GIS that shows geographic information using well-established cartographic toolsoThis definition includes mental maps. However, here the map definition assumes that the map is physical object that can be touchedMap, Cartography, and GISoMapping of Mapmaking: Refers to the production of a tangible map and is defined as the aggregate of technical processes including data collection, cartographic design and construction, and reproduction.oCartography: Concerns the art, science, and technology of making maps, together with their study as scientific documents and works of art, including maps, plans, charts, 3-D models and globes representing the Earth or any celestial body at any scale (International Cartographic Association). In addition to mapmaking, this definition includes the studies of maps.oGeographic Information Systems (GIS): defined as a computer-based system designed tocollect, store, analyze, and display spatially georeferenced data and their attributes. The key component is its ability to analyze spatial data. Maps are the major output of GIS.Contribution of GIS in mapmaking and cartographyoGIS has fundamentally changed cartography and they way in which we create, use, and think about mapsoGIS free map-makers from many of the constraints inherent in traditional paper mappingoGIS is a flexible medium for production of mapsA paper map is fixed and GIS allows mapping to be viewed at different scales
