    Types of maps: 1.Navigational 2.Topographic 3. General Reference Maps 4. Thematic maps
    Navigational maps: used for navigation by airlines, ships etc.
    Topographic maps: They give the idea of topography like the altitude etc. Denser the dots, steeper the location. Sparser the dots, lesser slope of the elevation.
    General Reference maps: they are most widely and commonly used. They have two sub categories: a) Political maps (give the political boundaries, enmarking the names of places like districts, states, countries, continents etc.) b) Physical maps: They give the idea of the type of land like mountains etc, rivers forests etc.
    Thematic maps: A result of GIS(geographic information system), where the computer programs generate the maps, laying down the trends of different characteristics. Mostly used by geologists Types: Dot density, proportional symbol, flow, chorochromatic, choropleth, isopleth etc.
