If you are a PowerPoint creator such as a designer, teacher, or someone who creates PowerPoints in the office, you know that getting a good quality map into PowerPoint is not the easiest of things you can do. It might involve buying some expensive maps that come only in EPS or Adobe Illustrator formats. Again, these open only in Adobe Illustrator or any of the other few high-end graphic applications that are more oriented towards professional graphic designers rather than PowerPoint creators.
And even if you manage to go so far, you still need to get your maps into PowerPoint – for that you will need to export to a graphic file format that PowerPoint understands. And then you’ll discover that none of those maps can be easily edited using PowerPoint’s own tools. By this time, you probably give up the whole idea of using a map in your presentation!
That’s the reason I was so happy to see a collection of maps that were actually PowerPoint presentations.
