If a picture is worth 1000 words, using multimedia in your travel writing speaks volumes.
Thanks to numerous open source applications, travel writers can now quickly and easily include video, timelines, data visualizations, and other interactive media directly into their travel articles.
The following lists five indispensable tools for travel writers looking to add content in new and exciting ways:
Umapper  makes it simple to customize maps, which is especially useful for travel writers covering numerous locations in their piece.
For example, if you’re writing an article on US road trips, you can create an interactive map of your route.
Umapper also lets you include images, annotations and video within your maps.
For example, if you’re doing a travel piece on cooking schools in France, you can record a short video at each school and add it atop the map.
Dipity  creates timelines in just a few simple clicks. It seamlessly integrates video, audio, images, text, links, social media, location and timestamps.

Created and maintained by IBM, Many Eyes  lets you take your data and publish it in interesting new visualizations.

As you drag your mouse across the screen you’ll notice each country pops up. This
provides an interactive backdrop to your travel piece.
Socialcam  is a mobile app lets you instantly upload videos from your smartphone to blogs, Facebook, Twitter and other social media sites.
If you’re doing a piece on the top New York City bars, simply record a short snippet of each bar and upload it using this app.
