Trustworthy COVID-19 Mapping: Geo-spatial Data Literacy Aspects of Choropleth Maps

Area of Science:

• Geographic Information Systems (GIS)
• Spatial Data Analysis
• Public Health Communication

Background:

• The COVID-19 pandemic necessitated widespread spatial data visualization.
• Geographic Information Systems (GIS) and web mapping technologies facilitate rapid map creation.
• Ease of map production has led to potential disregard for cartographic principles.

Purpose of the Study:

• To raise awareness about the power of thematic maps for understanding disease spread.
• To educate non-cartographers on creating trustworthy thematic maps.
• To prevent the creation and dissemination of misleading spatial data visualizations.

Main Methods:

• Review of principles for creating effective thematic choropleth maps.
• Discussion of the importance of geospatial data literacy.
• Analysis of common pitfalls in map creation during the pandemic.

Main Results:

• Many COVID-19 maps lack adherence to fundamental cartographic principles.
• Geospatial data literacy is crucial for interpreting spatial data reliability.
• Misleading maps can lead to significant public misinterpretation.

Conclusions:

• Promoting geospatial data literacy is essential for accurate spatial data representation.
• Adherence to cartographic best practices ensures the creation of trustworthy thematic maps.
• Effective thematic maps are vital tools for public health communication and understanding global phenomena.
