Multimedia Google Earth placemarks

Gavin Richards has extended my post on adding images to Google Earth windows with an illustrated article that explains how to incorporate a variety of digital assets into a placemark. Excellent effort Gavin!

Tom Biebrach has produced a kmz file linked to a geotagged video explaining Ogmore estuary. It’s a brilliant piece of work!

Tip for adding a picture to a Google Earth placemark

I recently created a placemark for the Sears Tower, Chicago, as part of a lesson on the characteristics of the central business district. I wanted to include a picture in the information window, as well a a link to the relevant wikipedia article.

The resulting placemark looks like this:

In order to add a picture to the information window, simply hunt around for a suitable image and then add it to the placemark information box, using a simple snippet of html.

Using the Sears Tower placemark for an example it works like this:

Replace all the code between the apostrophes with the URL of the image you want to include. This can be found by right clicking on the image and choosing Copy Image Location in Firefox, or Copy Shortcut in Internet Explorer.

This is a brilliant take on the London tube map

The map has subsequently been removed following threats by London Underground. Boing Boing has more, and a link to a mirror version.

3D Megastructures in Google Earth

ZNO blog has added some superb 3D models of several of the world’s megastructures, both existing and proposed; including the Burj Dubai, the Shard, London Bridge, UK, and the Millau Viaduct in France:

Using Google Earth to make wind farm decisions

I’ve just completed an article on the use of Google Earth as a teaching tool to make decisions about wind farm locations. Read article: Investigating Wind Energy with Google Earth

The suggested activites make use of a number of web sites. Creative Commons images linked to Google Earth come from Geograph. The MAGIC interactive map, an excellent UK government resource provides geographic information on a wide range of environmental themes. The lesson also uses the DTI wind speed database.

Investigating Wind Energy gets students to use a number of fairly simple, yet powerful applications to arrive at a decision about a site for a wind farm. They are handling real geographical data, giving the task lots of credibility. Wind energy is an emotive subject and the exercise will get students to question their own values and attitudes. There is plenty to challenge students of different abilities along with an option to extend the activity with some simple modelling in Sketch Up and Photoshop Elements.

I would welcome feedback!

Taff Ely Wind Farm Google Earth model

Following a post by Tom Biebach at SLN, I’ve produced a Google Earth model of Taff Ely wind farm. Download Google Earth file here. This is a high-resolution area so the quality is remarkably high. Turn on terrain (setting 2) for maximum effect!

The file will be part of a teaching activity which is currently in preparation
