Working with Maps

Map formats
All maps in the Digital Atlas are available in a variety of formats and sizes depending on their end purpose. Briefly, maps intended for on-screen viewing have been prepared as JPEG (.jpg) files and saved in four different sizes (map views), whereas those intended for printed use have been saved as PDF (.pdf) files in one size only. See About the Maps for a fuller explanation of these differences.

Map views
The four different JPEG file sizes are:

  • Thumbnail (miniature) image of the full map, used as a visual pointer in indexes and search results.
  • Almost full-size map image, placed in-line in chapters.
  • Normal (full-size) view, appearing together with additional information (years covered, further reading, etc.) and a list of related maps plus icons for zooming, printing and downloading.
  • Expanded view (65% larger than normal view), also with additional information and icons.

Changing views
It is simple to open a map in normal and expanded view.

  • To display a map in normal (full-size) view, click on its thumbnail or in-line chapter image. Return to the previous view by clicking on the back arrow.
  • To display a map in expanded view, click on the Zoom icon while in normal view. Return to the normal-sized map by clicking on the Reduce icon or back arrow.

Normally, thumbnail and in-line chapter images can only be printed with their associated web page. To print these images on their own, first open them individually in a separate window by right- or Ctrl-clicking on the actual image, then use your normal print command (Ctrl-P for Windows or Cmd-P for Mac).

Likewise, a printout of maps in normal (full-size) and expanded view includes any additional information for that map. However, maps can be easily printed alone or together with other matter on their web page.

  • To print the map together with any additional information, click on the Print icon or use your normal print command.
  • To print the map only, first open it separately then print this window (as described above for printing thumbnail and in-line chapter images).

In all cases, what is printed is the chosen JPEG image. For a much higher quality result, download and print the PDF file.

Downloading for presentations and other on-screen use
Use only JPEG (.jpg) map files for on-screen use, e.g. when importing a map file into a presentation program like Microsoft Powerpoint, Corel Presentations, OpenOffice Impress or Apple Keynote. In most cases, the normal (full-size) version will fit neatly on a presentation screen.

These files can be downloaded in two ways:

  • To download any map (including thumbnail and in-line images), right-click or Ctrl-click on the image and choose ‘Save image’.
  • To download a map in normal and expanded view, you can also click on the JPEG icon. The map will open in a new window. Right-click or Ctrl-click on the image and choose ‘Save as’.

In both instances, you will be prompted to assign a name and destination for the downloaded file.

Alternatively, it is also possible to right-click or Ctrl-click on the image, choose ‘Copy’, and then directly paste into your presentation program.

Downloading for use in printed material
For best results when saving a map for inclusion in a publication or in any other printed material, use the PDF (.pdf) file. (Note that you or your publisher may convert these PDF files to another format, e.g. TIFF, before printing. Conversion guidelines are found here. The high-resolution PDF files found in the Digital Atlas are perfectly adaptable to such a conversion.)

Only map files in normal and expanded view can be downloaded as PDFs. To do so, click on the PDF icon. The map will open in a new window. Choose ‘Save as’ and, when prompted, assign a name and destination for the downloaded file.

Remember that the conditions of use require that you include the following attribution statement: ‘From Robert Cribb, Digital Atlas of Indonesian History (Copenhagen: NIAS Press, 2010), reproduced with permission.’
