• A proportional symbol map would be better if the subject being studied had discrete units which could be
represented individually.
• A proportional symbol map would be better if the subject being studied had varying sizes and intensities
A proportional symbol map would be better if the information being represented stayed consistent across similar locations and changed gradually over different distances.

A geographer may decide to use a proportional symbol map over a dot density map for a few reasons. First, if the information being represented is quantitative data in the form of discrete units, a proportional symbol map would be more suitable. This is because proportional symbols can represent different quantities based on size or intensity, allowing for a clearer representation of the data.
Additionally, a proportional symbol map would be better if the subject being studied has varying sizes or intensities that need to be highlighted. Dot density maps, on the other hand, are more suitable for representing the distribution or density of a particular phenomenon.
Lastly, a proportional symbol map would be more appropriate if the information being represented remains consistent across similar locations and changes gradually over different distances. This allows for a more visually accurate representation of the data and aids in making comparisons between different regions or areas.
A geographer might decide to use a proportional symbol map over a dot density map for several reasons:
1. Quantitative data: If the information being represented is quantitative data in the form of numerical values or ratios, a proportional symbol map would be more suitable. This is because proportional symbol maps use different-sized symbols to represent varying values, allowing the viewer to quickly understand the distribution and intensity of the data.
2. Discrete units: If the subject being studied has discrete units or categories that can be represented individually, a proportional symbol map can effectively display this information. Each unit or category can be represented by a distinct symbol, making it easier to differentiate and visualize the distribution of different elements.
3. Varying sizes and intensities: Proportional symbol maps are particularly useful when the subject being studied has varying sizes or intensities. For example, if the data represents population sizes or levels of economic development in different locations, a proportional symbol map can accurately represent these variations by using symbols of different sizes or intensities.
4. Consistent representation across locations: If the information being represented remains consistent across similar locations and changes gradually over different distances, a proportional symbol map can effectively illustrate this pattern. The use of symbols proportional to the data values allows for a clear visualization of gradual changes, making it easier to understand spatial patterns and trends.
Overall, the decision to use a proportional symbol map over a dot density map depends on the nature of the data and the specific patterns that need to be depicted. By considering the characteristics of the data and the desired visual representation, geographers can choose the most appropriate map type to effectively convey their findings.
