    Study Notes

    Cartography and Geographic Concepts

    • Cartography: The art, science, and technology involved in making maps.
    • Geographic Grid: A system formed by imaginary intersecting lines, aiding in locating points on Earth's surface.

    Latitude and Longitude

    • Latitude: Measured in degrees from the equator (0°) to the poles (90° north or south).
    • Longitude: Measures angular distance east or west from the Prime Meridian, ranging from 0° to 180°.
    • Prime Meridian: The 0° longitude line, located at the Royal Observatory in Greenwich, England.
    • International Date Line: Generally follows the 180° meridian; marks where each new day begins.

    Globe Properties

    • Meridians are equal in length and meet at the poles; they are true north-south lines.
    • Parallels of latitude are parallel to the equator and shorten as they approach the poles.
    • Meridians and parallels intersect at right angles, maintaining consistent scale in all directions.

    Map Projections and Types

    • Map Projection: Techniques to represent the Earth’s curved surface on flat maps.
    • Equal Areas Projection: Maintains area proportions; shapes may be distorted.
    • Conformal Projections: Preserve shape for small areas, keeping angular relationships accurate.
    • Equidistant Projections: Show true distances from one or two central points but distort distances elsewhere.
    • Azimuthal Projections: Display true directions from a central point to other locations.

    Types of Thematic Maps

    • Topographic Maps: Illustrate terrain shape and elevation, utilizing contour lines.
    • Contour Interval: Vertical spacing between contour lines, indicated on the map.
    • Choropleth Maps: Represent variation in a phenomenon across areas.
    • Area Cartogram: Area sizes adjusted to reflect specific variables (e.g., population, income).
    • Isoline: Lines connecting points of equal elevation on maps.

    Movement and Remote Sensing

    • Flow Line Maps: Show linear movement between locations, can be qualitative or quantitative.
    • Remote Sensing: Method to gather information about an object or area without direct ground contact.
    • Landsat Satellites: Known remote sensing spacecraft that monitor various Earth features like deforestation and water quality.

    Geographic Systems

    • Global Positioning System (GPS): Determines exact locations using signals from satellites.
    • Geographic Information System (GIS): A computer-based system for managing and analyzing geographically referenced data.
    • Geographic Database: A digital collection of geographic information from various sources.

    Scale and Contours

    • Scale: The ratio relating measurements on a map to actual measurements on Earth.
    • Contour Line: Primary symbol on topographic maps representing elevation changes.
