  2. Scale (map) - Wikipedia

    en.wikipedia.org/wiki/Scale_(map)

    The terms are sometimes used in the absolute sense of the table, but other times in a relative sense. For example, a map reader whose work refers solely to large-scale maps (as tabulated above) might refer to a map at 1:500,000 as small-scale. In the English language, the word large-scale is often used to mean

  3. Topographic map - Wikipedia

    en.wikipedia.org/wiki/Topographic_map

    The various features shown on the map are represented by conventional signs or symbols. For example, colors can be used to indicate a classification of roads. These signs are usually explained in the margin of the map, or on a separately published characteristic sheet. [17] Topographic maps are also commonly called contour maps or topo maps.

  4. Map series - Wikipedia

    en.wikipedia.org/wiki/Map_series

    In most European countries, the largest scale topographic map series is a 1:25.000 scale series. Notable exceptions are Austria (1:50,000) and Finland (1:20,000). Many non-European states limit the largest scale of their map series, usually to 1:50,000 scale, frequently due to the large size of the country covered (and hence for financial reasons).

  5. Orienteering map - Wikipedia

    en.wikipedia.org/wiki/Orienteering_map

    The map scale depends on the purpose of the competition and also the standard used, for example, a map used in a foot orienteering long distance event has a scale of 1:15000. The map is printed in six base colours, [ 3 ] which cover the main groups: Land forms, rock and boulders, water and marsh , vegetation, and man-made features, and an extra ...

  6. City map - Wikipedia

    en.wikipedia.org/wiki/City_map

    The scale of a city map is usually between 1:10,000 and 1:25,000. Densely settled downtown areas will sometimes be partly drawn in a larger scale, on a separate detail map. In addition to linear true to scale maps, there are also maps with variable scale, for example where the scale gradually increases towards the city centre ( aerial ...

  7. Cartographic generalization - Wikipedia

    en.wikipedia.org/wiki/Cartographic_generalization

    This is the addition of symbols or other details on a smaller scale map to make a particular feature make more sense, especially when such understanding is important the map purpose. A common example is the addition of a bridge symbol to emphasize that a road crossing is not at grade, but an overpass. At a large scale, such a symbol may not be ...

  8. Scale (geography) - Wikipedia

    en.wikipedia.org/wiki/Scale_(geography)

    E.g. a spatial analysis of the entire United States might be considered a large-scale one, while a study on a city has a relatively small scale. Cartographic scale or map scale: a large-scale map covers a smaller area but embodies more detail, while a small-scale map covers a larger area with less detail. Operational scale: the spatial extent ...

  9. Conformal map projection - Wikipedia

    en.wikipedia.org/wiki/Conformal_map_projection

    Many large-scale maps use conformal projections because figures in large-scale maps can be regarded as small enough. The figures on the maps are nearly similar to their physical counterparts. A non-conformal projection can be used in a limited domain such that the projection is locally conformal. Glueing many maps together restores roundness.
