Save Maps as Map File

Maps may be saved as either an image file (*.png) or an Epi Info™ 7 Map File (*.map7). The map file format saves the map along with the underlying data layers. An Epi Info™ 7 Map File can only be opened using the Epi Info™ 7 software. An image file (*.png) can be opened with any image-viewing program (e.g., Microsoft Paint). When opened, the map file will automatically update the map based on any changes to the dataset. Create and save the map file by clicking on the Save icon in the Epi Map toolbar.

  1. Click the Save button. A Save As dialog box opens.

  2. Choose a file destination from the folder drop-down list at the top of the dialog box and type the desired file name in the File name box. The map is saved in the *.map7 file format, which can be opened later by Epi Info™.
  3. Click the Save button. A Save Successful dialog box appears.

Save Maps as an Image

The image format saves only the map image in a *.png file format. This image file can be inserted into documents or opened with a multitude of software applications. Save the map as an image by clicking on the Save as Image button in the Epi Map toolbar.

Note: The Epi Info™ software will not open or edit a map saved in image format.

  1. Click the Save as Image button. A Save As dialog box appears.
