Map your photos using Google Maps

Using Google Images and Google Maps you can easily create a map using an album of geotagged photos. Geotagged photos are those that include data on the location they were taken. Most modern mobile phones have this feature as do some digital cameras. If you are not sure a quick search on the Internet will tell you if this option is available and how to enable it.

Below is a map showing the location of a number of images taken in and around Hornsea on the Holderness Coast using an iPhone and a drone.

Looks complicated? Don’t worry, it’s not! Just follow the steps below.

To begin with, you will need to upload your geotagged photos to a new album in Google Photos. To do this login to your Google account and go to Next create a new album by clicking +Create in the top right corner, then select Album.

Give the folder a title then upload the images you want to map.

Next, go to and select +Create New Map (top left corner). Your new map will open and be called Untitled map. Give your image a suitable title by clicking untitled map in the top left window.

Rename your map

Rename your map.

Click Save.

Next click Import (under the first layer which is called Untitled layer).

Click import

Click Import

Click the Photo albums tab. Next, locate the album where your photos are stored. Select all the images you want to import onto the map.

Next, click Select. The photos will then be copied onto your map.

This will create at least one layer containing your images and an icon of each image will be displayed on the map.

You will notice that each photograph has been given a title based on the location it was taken. You should go through these and rename them as appropriate. Once you’ve finished you can share your map with others by clicking Share > Change > On. You can then share the URL. You can also embed the map on a website by clicking the three dots next to the map title. Then select Embed on My Site.

How to show physical changes over time using images in Geography

Illustrating physical changes over time is a great way to demonstrate the impact of processes in geography. The good news is that there are lots of free, easy to use tools online to do this.

A good starting point is creating an animated GIF. An animated GIF is an image which contains a number of images or frames in a single file. The frames are presented in a specific order in order to convey animation. The animated GIF below shows changes along the coast to the south of the sea defences at Withernsea on the Holderness Coast.

Creating the animated GIF above involved capturing two aerial images from Google Earth which were then combined using free, online GIF making software. The steps for creating this image are listed below.

Step 1 – Download and install Google Earth

Step 2 – Open Google Earth and choose the location you want to create an animated GIF for.

Step 3 – Go to View > Historical Imagery

Step 4 – Use the slider to select your first image.

Step 5 – Click the Save Image icon (it looks like a pin on a map). This will download the image to your computer.

Step 6 – Give the image an appropriate title. Choose the resolution you want to use. The higher the resolution the clearer the image (and the larger the image file).

Step 7 – Click the Save Image button.

Step 8 – Use the slider to select the date of your next image. Repeat steps 5-7.

Step 9 – You can capture any number of images for your animated GIF.

Step 10 – You now need to create your animated GIF from the captured images. To do this go to

Step 11 – Click Upload Images and upload the images you want to use.

Step 12 – Experiment with the Animation speed slider. Once you are happy with the speed click the Create GIF Animation button.

Step 13 – Click download the GIF

Another technique to illustrate changes over time is to superimpose one image over another. The image below shows the coastline south of Withernsea in 2017 with the coastline from 2007 superimposed over the top.

The image that has been superimposed (2007) is partially transparent to reveal the 2017 coastline. If you have two separate images to merge then head over to
