Add dynamic Satellite Images to your Dashboardġ. The next group of steps walks you through how to add a box to your dashboard that pulls up this embedded satellite image when a user clicks on a particular circle. You can see that the actual numbers for Latitude and Longitude have been replaced with field names and

&output=svembed – this is a key parameter that makes sure the website you embed in your viz doesn’t include the entire site – just the map itself.

&t=h – this specifies the type of map.

Higher numbers zoom in, lower numbers zoom out

&z=17 – this specifies the zoom level.

Note that if you have an address field instead of Lat/Long, you can put an address after “q=” as well Breaking down the elements of the url, we can see that after the latitude & longitude, there are three parameters in the url: The url can be simplified a little bit as follows:Ĥ. A Google Maps search for a particular Latitude & Longitude (say, 48.445781 and -122.341108) yields a link url like this:ģ. First, notice that the data file contains Latitude ( “LAT”) & Longitude ( “LON”) for each bridge.Ģ. The first group of 5 steps shows you how to create a url for each bridge, and the second group of 5 steps shows you how to add a box to your dashboard to pull up the bridges.ġ. How to embed a Google satellite image in a Tableau Public visualization: Instead, I used a little-known feature in Tableau Public – embedded web pages (similar to the Embedding YouTube post from a few weeks ago). I didn’t have to take a screen shot of each satellite image – that would be way too much fun. What’s notable about this dashboard is that you can click on any of the 2,489 circles on the map and bring up an embedded Google satellite image of the bridge within the dashboard itself. (For this post, I owe a word of thanks to Andrew Beers – VP of Product Development at Tableau, for the raw data, and Mike Klaczynski – Data Analyst on the Tableau Public team, for showing me this method).Īt the Seattle Hacks/Hackers event last night, we built an interactive data dashboard that allows the reader to explore bridges in the state of Washington, where a bridge crossing the Skagit River recently collapsed into the water after being struck by a truck carrying an oversize load. Nelson Davis has a recent blog post that addresses issues with the method outlined here, which doesn’t work quite like it used to. UPDATE, May 2015: Google is constantly changing their Maps service.
