Biodiversity informatics integrates large amounts of data from different sources. Its tools can be used if the data provided are well-structured. This means the original data collectors, who work in a small area, need to provide well-structured data. This affects how students in the contributing fields are taught. Specialist data aggregators help work out the standards and how to implement them. They bring together data from very large areas, often the whole world, and enable some data visualizations and analyses. The maps, graphs, and analyses of data concerning Covid19 are an example of biodiversity informatics in action.
