Geotagging images using Google Earth

Published by tbarrett under Geotagging, Google Earth

This afternoon we embarked upon the most challenging technology related work we have done to date in Year 5. The children are 4th graders, 9 or 10 years old.
Recently we all went to Perlethorpe Activity Centre to support our work on rivers - we measured the velocity and profile of the River Meden, as well as enjoying a lovely sunny walk around the grounds of Thoresby Hall. As we walked round I snapped away some pictures and this afternoon we had the opportunity to geotag them in Google Earth(GE).
Perlethorpe Visit - a photoset on Flickr

The children have used GE many times already this year, so I decided to take advantage of this knowledge as opposed to using Google Maps or Quikmaps as I have done in the past. The geotagging work ties nicely into their ongoing map skills development and is a good conclusion to the visit.

This video clip is one of the children completing the process of embedding an image from Flickr into a GE placemark, using the correct written code. (<img src=”">)It certainly was a challenge for the children but once they had written the code a number of times, and often corrected their mistakes, they were flying.

Here is what you have seen Kyle do in a step by step guide.

  1. Find an image stored somewhere online, study it carefully and try to pick up on any clues as to where it is. Remember when you geotag an image it should really be located where the photographer was standing when it was taken, not the subject of the image.
  2. Copy the location or url of the image - in Firefox you can just right click and “Copy Image Location”. IE take the URL from “Properties”
  3. Now navigate back to your new placemark in GE. Make sure you are looking at the properties window - you will add the code in the “description” part.
  4. If you just paste the address it will not display the image because you have not told the map to retrieve anything, it will just return a link. You need to add in a little code.
  5. All you need to do is ensure the image URL is encoded with the highlighted parts in the example below.
  6. <img src=”alovelypicture.online.234.jpg“>
  7. Now click OK. If you click on the placemark it should open up with the image inside.
  8. When embedding video or other media - just look for the “Blog This” option, and paste the generated code straight into the placemark balloon. Google video can be added pretty easily in this way.

The visual / spatial skills needed to correctly place an image on a map is an interesting one to explore. The children were looking very closely at what clues the image revealed as to the exact whereabouts of it.

I told the children that they would have had a successful afternoon if they could embed just one image in a placemark at the correct location. But, just as they often do, the children ran with it and tagged many pictures correctly on the map. A challenging but ultimately successful afternoon of GE mapping work.

(I will add a link to some example KMZ work as well as a Google Map of our work from today when I can.)

Half Term Review

I thought that I would reflect on what I have managed to do so far this half term with my class - it seems that we hit the ground running headlong into this web 2.0 thingy.

I have really enjoyed working with the children on the class blog - as one child said to me it gives them a voice. The sort of resources we have used are exciting and have minimal learning curves - they have been applying their ICT skills in real contexts. This is what it is all about (well to me anyway :) )

But I have also challenged the kids with stuff like embedding code into our wikispace - they have coped amazingly well.

So what have we done in the last 7 weeks:

Quikmaps - used this throughout our local history work, we basically geotagged old photos of the town. We added code to placemarks in Quikmaps, we then embedded the maps in our class wikispace. (Wow that sounds hard, but my Year 6’s did it)

Bubblr - in our Literacy we took Matilda photos from our Flickr account and made a simple comic strip of them and added simple speech and thought bubbles. We embedded these in our wikispace too.
READ MY PREVIOUS POST ABOUT IT
Blogging - we started our class blog and the children have really enjoyed it. At least once a week I do a lunchtime blogging club so kids can get online and write / comment and visit other school’s blogs.
READ MY PREVIOUS POST ABOUT IT
Wikispace - we have used this space to share our literacy writing and the work we have done in other subjects. I published the backing music for a song they were learning in music for example.
READ MY PREVIOUS POST ABOUT IT
Local Live - we used a shared collection to add points of interest around our town. This worked extremely well with one login too!
READ MY PREVIOUS POST ABOUT IT
Google Earth - This has been a regular feature of the half term and I am sure will continue to be. We have explored where news stories are from, visited Rome, Paris, London and Athens. We like to look at our Geovisitors and locate them on Google Earth. I have used Google Earth in my maths lessons.
READ MY PREVIOUS POST ABOUT IT
Mayomi - a lovely simple Flash based tool for mind mapping that we used to support our maths and literacy, easy to navigate and well presented. Cannot directly link to the map though when finished.
READ MY PREVIOUS POST ABOUT IT
Flickr - I have added photos, images and screen shots to our account and found it invaluable for the kids to make the most of some web 2.0 apps (like Bubblr) I have found the notes a simple success. ( I have also explored it as a photo resource for upcoming curriculum areas and it is amazing)
READ MY PREVIOUS POST ABOUT IT

Editgrid - we have set up an online space to share investigation results. Hopefully it will help the children better appreciate fair tests and reliability of results.

…that’s not to mention using digital cameras to record our science and our SMARTBoard work. ;)

So what is next - more of the same…?

I think I shall set myself some simple targets and you can hold me to these before Christmas (as long as Santa still comes :) )

  • Continue to apply the successful applications across the curriculum I have already used, so they are not just one offs.
  • Setup a session when the children moblog. (could be interesting!)
  • Explore parental permissions so children can take more photos and blog with these.
  • Setup a more structured daily blogging routine, children blogging in writing partners.
  • Answer: does having a world wide audience / platform really make a difference to the standard of the children’s writing?
  • Spread the word: get at least one other class in school blogging.
  • Get the children writing with TiddlyWiki.
  • Develop more international links via blogging etc.
  • Do a simultaneous science experiment with another class somewhere in the world.
  • Use Flickr notes more.
  • Look into purchasing a cameraphone for blogging purposes. (Will I need to change blog hosts?)

So there we are some simple targets…well i will reiiew these again at Christmas.

Adding images and video to Quikmaps

Following a comment from Sally on the “My Quikmaps Lesson” post I thought I would quickly explain how to add images, video even Bubblr strips to a placemark.

  1. So you have made a new map and you have added a placemark > What next?
  2. Find an image stored somewhere online. For the images I used in my local history lesson I used our class Flickr account.
  3. Copy the location or url of the image - in Firefox you can just right click and “Copy Image Location”.
  4. Now navigate back to the placemark on your map. Make you have clicked on it to open up the balloon - and that the cursor is blinking at you in the space.
  5. If you just paste the address it will not display the image because you have not told the map to retrieve anything. So you need to add in a little code.
  6. All you need to do is ensure the URL is encoded with the highlighted parts in the example below.

    (No spaces between the = and the url)

  7. Now close the balloon and click SAVE IT (bottom right hand corner) When viewing the saved map if you click on the placemark it should open up with an image inside.
  8. When embedding video or other media - just look for the “Blog This” option, Gand paste the generated code straight into the placemark balloon. Google video can be added pretty easily in this way.

Hope this helps. Let me know how you get on. :)

My Quikmaps lesson

Published by tbarrett under Geotagging, Mapping, Quikmaps, Wiki

Wow - what fun we had, this one really challenged the kids. Basically I wanted them to embed a historic photo of our town from Flickr into a Quikmap - they had to locate where to place the photo using some simple clues I gave them. A great Geography / History / ICT activity. Quikmaps seems to work differently in Internet Explorer then in Mozilla Firefox - in my class we use Firefox, but in the ICT suite we have IE installed, I might change that. The interface with the buttons seemed a little laggy and not as smooth and there were even problems with the appearance of the icon pallette.

260918621_6636f77542_m My Quikmaps lesson

The children soon managed very well and everyone used some code I had saved in a word document (like this] but I soon realised as I was explaining the above that we should take one thing at a time. So we just saved our maps - Quikmaps was obviously bombarded with maps in one account so struggled with the high traffic and I had a few Quikmaps - “OOPS APPLICATION ERROR” messages and was a bit concerned that the kids would lose there work. But they saved and as we used the back button and then saved again we had loads of duplicates. I contacted Ken over at Quikmaps and he said there were approx 54 maps from about 18 workstations!!, anyway we will be posting our maps up soon on the wiki so watch out.

This idea popped into my head in the middle of the night…

They seem to do that a lot. I can’t help but think over a few ideas as I drift off to sleep and I was mulling over the use of old and new photographs that we have been doing in our local history. I wanted to explore the use of GPS and geotagging to help us locate some of the old pictures. Well basically what I have come up with is a conceivable set of Geography/History/ICT based activities that would be great to do.

You would need.

  • GPS Receivers - hand held X 5 (one per group)
  • Network copy of Robogeo (geotagging software)
  • Digital cameras - X 5 (one per group)
  • Copies of old photos laminated to be taken out with you
  • Optional: portable mp3 recording equipment; iPod, iRiver

Prior to taking the children out you would need to locate whereabouts the old photographs have been taken and add these as placemarks into all 5 GPS devices - or you could just record the placemarks and ask the children to enter the lat and long as part of the task. (This task is assuming there has been some prior work using GPS devices within the school grounds for example)
So what would the task involve? I will break it into different steps. Essentially the main learning objective are

  • To understand and recognise the changes that have occured over time to different locations in your local area.
  • Use GPS and geotagging software to accurately locate the old photographs onto a modern day map.

The activities would be in this order:

  1. Locate each GPS placemark and match it to one of the old photographs the children have with them.
  2. At the exact location take an identical phtotgraph using the cameras - take time to frame the photograph exactly as the older one was taken.
  3. (After completing all of the photographs) Return to an ICT suite connect both GPS device and camera to computer and load Robogeo software. Match up each placemark (lat and long) from GPS to the photographs. [This can be done for the new set of photographs as well as the older set.]
  4. Export the finished work into many different formats: Google Earth, Google Maps, to flickr. Embed the map into a class wikispace.
  5. An added feature of RoboGEO is the ability to associate an audio file with the image. The audio files could be recorded using an iPod or other mp3 device and loaded onto the PC as well.

The activities might need a bit of support but they are certainly not out of reach for upper KS2 children.I am not sure how many primary schools own there own GPS devices though!

Geotagging: extended…

RoboGeo is now part of my software list, I purchased the simple program to help me tag my photographs I take. During our trip to the Norfolk coast I took many photos and recorded the locations using my GPS as before. I then loaded the photos into RoboGeo and edited the Lat/Lon manually; this is pretty time consuming and I think I will be getting a upgrade on my GPS soon so that I can connect to my PC and take advantage of down/uploading files.

 Geotagging: extended...

Once the information about the photographs location is completed you can export to Flickr / Google Maps / Google Earth. The latter creates KML or KMZ (if including the photos with the file) files and automatically opens in GE. There is even an option to plot a photo path or route; this adds a pathway in GE connecting your photo locations.

(The photo above shows the stamped data at the bottom)
