    Definition

    What is a Map?

    Reduced simplified representation of part (or all )ofthe earth showing relative size and position offeatures to some given scale and projection

    All types of maps

    Plans, Charts, 3D models, globes, animated mapsvirtual worlds etc at any scale

    Map scale

    MAP

    GROUND

    Ground distance

    Map scale = Map distance : Ground distance

    Map distance

    Coordinate system

    Coordinate system

    Show geographical coordinates latitude,longitude(,)

    Projected coordinates (E, N)

    Show grid in mapped area

    Network of lines showing constant rectangular coordinates

    Allows for detailed calculation and positioning on the map

    Used on large to medium scale maps
