Study Notes
Bertin's Theory
- Bertin's Theory emphasizes the relationship between the type of data and the appropriate symbols for its representation in maps.
Measurement Scale
-
Qualitative (categorical) data
- Nominal data: Categories without ordering (e.g., gender, race, landform).
- Ordinal data: Ordered categories (e.g., school grades, world ranking).
- Interval data: Difference between measurements but no true zero (e.g., temperature, year).
-
Quantitative/numerical data
- Ratio Data: Difference between measurements with a true zero (e.g., age, height, speed).
MSU Color System
- Hue: Represents a specific color (e.g., red, blue, green).
- Chroma (intensity): The saturation of a color, indicating its richness or purity (e.g., light blue vs. dark blue).
- Value: The difference in lightness from white to the darkest version of a specific color (e.g., light green vs. dark green).
Mapping Data
- Qualitative data: Primarily use hue to represent categories.
- Quantitative data: Use chroma or value (lightness) for visualizing numerical data.
Choropleth Maps
- Choropleth maps are thematic maps that use color variations to represent quantitative data across geographical areas.
Geo-visualization
- The process of constructing a visual image in the mind from raw data.
- Involves transforming raw data into displayable images, making information understandable for humans.
- Encompasses exploring, analyzing, synthesizing, and presenting geospatial data.
- Integrates approaches from cartography with disciplines like scientific visualization, image analysis, and GIS.
Gestalt Effect
- In cartography, it refers to the viewer perceiving all map elements as a unified whole.
- The Gestalt principles influence how we interpret visual information.
