About Mapping

  • What Is a Map?

    A map is a representation of geographic data. Map data represents a set of geographic locations or properties.

  • What Is Geospatial Data?

    Geospatial data represents positions on the surface of a planet through ordered coordinate pairs or in matrix format.

  • Vector Geodata

    Vector geodata consists of sequentially ordered pairs of geographic (latitude, longitude) or projected (x,y) coordinate pairs.

  • Raster Geodata

    Raster geodata represents map data in matrix format.

  • Latitude and Longitude

    Latitude and longitude specify the position of a point on the surface of a planet. They are defined as angles between the point, the equator, and the axis of rotation.

  • The Shape of the Earth

    The Earth can be modeled with increasing precision as a perfect sphere, an oblate spheroid, an ellipsoid, or a geoid.

  • Map Projections and Distortions

    A map projection transforms a curved surface such as the Earth onto a two-dimensional plane. All map projections introduce distortions compared to maps on globes.
