3.7.3 Visualization and Analysis

Data producers can use a variety of tools in order to see their data and better understand and analyse them. Whether it is a map, a chart or a table, vizualisation tools provide options for combining various informations into a single view which helps to identify trends or anomalies.

Data visualization tools can help refine the data validation process. For example, using a map to view data point distribution and sampling locations can help identify possible errors in geographical coordinates.
