Introduction

The Map feature in Epi Info™ 7 is a versatile tool that displays geographic data on a map. Epi Map has the ability to display multiple views from the same dataset. Datasets can be filtered or shown over a series of time using features in the Epi Map tool. Users can tailor these features to create a customized map containing public health data.

Information displayed in the main map window appears in the form of layers. Data layers add information in the form of case cluster maps, choropleth maps, or dot density maps. Reference layers add geographical boundaries and markers from shapefiles, a map server, or KML (Keyhole Markup Language) files. The use of reference layers allows Epi Map to uniquely identify and designate display settings from both internal and external data sources. Users may modify or filter map data using data layers, the tool for which is located at the bottom of the main Epi Map window.
