Introduction

Rationale: Representative Fraction (RF) is expressed as a ratio (e.g., 1:100,000) where both numerator and denominator use the same unit, making it unit-less and universally understood across languages.

Rationale: Cadastral maps are very large-scale maps created to record property boundaries, land ownership, and facilitate land taxation and revenue collection.

Rationale: Proportional symbol maps scale symbols (circles, squares, spheres) in direct proportion to the numerical value of the data attribute at specific point locations.

Rationale: Tobler's First Law encapsulates spatial dependence and distance decay, serving as the foundational axiom for spatial analysis and cartographic interpolation.

Rationale: Isarithmic maps (like contour maps, isotherms, isobars) use isolines to portray continuous spatial fields.

Rationale: Choropleth maps require standardized or normalized data (densities, rates, percentages) rather than absolute totals to avoid misleading visual bias across unequal enumeration units.

Rationale: Jacques Bertin published 'Semiology of Graphics' in 1967, systematically categorizing visual variables such as size, value, texture, color, orientation, and shape.

Rationale: Maps with fractions representing larger numbers in the denominator like 1:1,000,000 are small-scale, while 1:10,000 shows high detail over small areas, classifying it as large-scale.

Rationale: Dot density maps use dots of a set value to depict the spatial distribution and concentration of phenomena like population, livestock, or crops.

Rationale: General reference maps (like topographic and atlas maps) provide a general framework showing multiple physical and cultural features rather than a single specific theme.

Rationale: Hue is primarily qualitative, making it ideal for differentiating distinct categories (like forests vs. urban areas), whereas value and size are quantitative.

Rationale: A linear scale enlarges or reduces proportionally with the map image, whereas numerical or statement scales become invalid if the map is resized.

Rationale: Capital city locations represent discrete point features without quantitative scaling in that context, making it qualitative point data.

Rationale: Hill shading illuminates terrain features from a specific angle (typically northwest) to create realistic 3D shadows and highlights on maps.

Rationale: Conformal (orthomorphic) maps preserve local angles and shapes correctly around any point, although area is distorted.

Rationale: Choropleth maps suffer from the Modifiable Areal Unit Problem (MAUP), where visual interpretation changes depending on how the enumeration zones are drawn.

Rationale: Elevation is represented using contour lines, which are specialized isolines connecting points of equal height.

Rationale: Quantile classification places an equal number of data features into each class, ensuring balanced visual representation but potentially grouping dissimilar values.

Rationale: Flow line maps use lines with widths proportional to movement volume to portray directional movement and interaction between places.
