    Study Notes

    Geographical Information Systems (GIS)

    • GIS is a tool for comprehending and relating to the "what," "when," "how," and "why" of the world by answering "where."
    • GIS is primarily concerned with geography and learning about the world in which we live.

    Mental Maps

    • Mental Maps are stored, brain-based representations of the environment for our world.
    • They demonstrate familiarity with our neighborhood and relationship with our local surroundings.
    • Humans prefer to think spatially according to their preferences.

    Asking Geographic Questions

    • Clarifying and dividing questions into manageable chunks are extremely useful skills when utilizing a geographic information system.
    • Question types include:
      • Geographic Location
      • Geographic Distribution
      • Geographic Association
      • Geographic Interaction
      • Geographic Change
      • Geographic Concepts

    Geographic Concepts

    • Location: a point on the Earth's surface, can be referenced using Latitude and Longitude, Geographic Names Information System (GNIS), and Geo-Coding.
    • Direction: the location of an object relative to other objects along a line, can be Egocentric, Landmark, True North, Magnetic North, and Grid North.
    • Distance: the degree of separation between two locations, can be measured in Nominal, Absolute units, and other units.
    • Space: an abstract concept that is typically discussed rather than measured, including Topological space.
    • Navigation: movement and travel with a specific destination, often relying on Landmark, Route, and Survey knowledge.

    GIS for Today and Beyond

    • A GIS is a specialized computer application that stores, modifies, processes, and displays geographic data and information as maps.
    • Examples of GIS software include ESRI ArcGIS, Pitney MapInfo, and Open Source GRASS.
    • All GIS software consists of a database management system capable of managing and integrating spatial and attribute data.

    Spatial Data and Attributes

    • Spatial Data: facts regarding the location and position of phenomena on the Earth's surface, such as Streets, Buildings, Lakes, and Countries.
    • Attributes: characteristics and qualities of features and occurrences located on the Earth's surface, such as Name, Street No., Depth, and Population.

    GIS Approaches

    • Application Approach: focuses on the use and application of GISs to address problems, such as answering questions, aiding decision-making, and producing maps.
    • Developer Approach: focuses on the development and creation of GIS systems, including designing and building spatial databases and applications.

    Multi-layer Cake

    • A classic method to describe and represent a geographic information system, where each layer of the cake reflects a distinct geographical topic.
