  2. Thematic map - Wikipedia

    en.wikipedia.org/wiki/Thematic_map

    According to Arthur Robinson, thematic maps were largely an Industrial Age innovation, with some Enlightenment-era roots; almost all of the modern graphical techniques were invented between 1700 and 1850. [6]: 26 Prior to this, the most important cartographic development was the production of accurate general base maps. Their accuracy improved ...

  3. Cartographic design - Wikipedia

    en.wikipedia.org/wiki/Cartographic_design

    This issue assumes more importance as the scale of the map gets smaller (i.e. the map shows a larger area) because the information shown on the map takes up more space on the ground. For example, a 2mm thick highway symbol on a map at a scale of 1:1,000,000 occupies a space 2 km wide, leaving no room for roadside features.

  4. Contour line - Wikipedia

    en.wikipedia.org/wiki/Contour_line

    A contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes. [4] The contour interval of a contour map is the difference in elevation between successive contour lines. [5] The gradient of the function is always perpendicular to the contour ...

    en.wikipedia.org/wiki/Borden_Dent

    Dent's specialization as a geographer and cartographer was thematic mapping.He defined thematic maps as those that show “the spatial distribution of some geographical phenomenon,” [5] in contrast with general-purpose or reference maps that “display objects (both natural and man-made) from the geographical environment.” [5] He further explained that because thematic maps deal with a ...

  6. Dot distribution map - Wikipedia

    en.wikipedia.org/wiki/Dot_distribution_map

    A dot distribution map (or a dot density map or simply a dot map) is a type of thematic map that uses a point symbol to visualize the geographic distribution of a large number of related phenomena. Dot maps are a type of unit visualizations that rely on a visual scatter to show spatial patterns, especially variances in density.

    The Geographic Information Science and Technology Body of Knowledge (GISTBoK) is a reference document produced by the University Consortium for Geographic Information Science (UCGIS) as the first product of its Model Curricula project, started in 1997 by Duane Marble and a select task force, and completed in 2006 by David DiBiase and a team of editors.

  8. Geographic information science - Wikipedia

    en.wikipedia.org/wiki/Geographic_information_science

    Geographic information science (GIScience, GISc) or geoinformation science is a scientific discipline at the crossroads of computational science, social science, and natural science that studies geographic information, including how it represents phenomena in the real world, how it represents the way humans understand the world, and how it can be captured, organized, and analyzed.

  9. Isoline - Wikipedia

    en.wikipedia.org/wiki/Isoline

    Isoline may refer to: Contour line (line of constant elevation or depth, sometimes used to describe other lines of constant value) A line of constant value on a map or chart. Examples include isobar (equal barometric pressure), isotherm (equal temperature), and isohyet (equal precipitation). Isoline, an opera by André Messager
