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 measurment 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
