Adding a Data Layer

Epi Map offers the option to add Data Layers; that is, to use layering to create different map views and ways of viewing the related data. Epi Map offers four types of Data Layer:

  • Choropleth – areas are shaded or colored in proportion to a measurement or variable
  • Dot Density – dots show the presence of a feature, but not specific locations
  • Case Cluster –coordinates of cases are shown clustered when zoomed out
  • Spot Map – shows the coordinates of specific points of interest
