This page describes creating locative experiences for the Nokia flavour of Treasuremapper. Designing treasuremaps for the Nokia Flavour is easy, as it's mostly a WYSIWYG (What You See Is What You Get) experience. On this page we'll create one such experience as an example: we'll create a childrens game in which they have to search for hidden gnomes.


A Treasuremap

Technically speaking Treasuremaps for the Nokia flavour are really folders that have both a map file and some media files in them. The folder is named after your project, and so is the mapfile inside. In the case of our gnome project, we will fill a folder named "Vondelgnomes" with a mapfile by the same name (Vondelgnomes.kml). Also inside are the mediafiles that correspond to areas on the map. In the case of this example we have an image(gnome1.jpg) and a soundfile (gnome1.wav).


Creating the map file

Treasuremapper uses Google Maps as it's mapmaking tool. Using Google 'My Maps' you can easily draw on maps, and share these drawings with others. Google has a great video that explains how it works. Treasuremapper uses this same functionality, but instead transfers the map to the mobile phone that has Treasuremapper installed.

First, go to, and sign in using your google account. You can now create a "My Map" by clicking on My Maps.


Let's make a map in which the picture of a gnome is shown when the user walks near to the Blue Teahouse, a cafe in the middle of Amsterdam's Vondelpark. Here we've prepared an image (gnome1.jpg) and a soundfile (gnome1.wav). Create a new My Map. In this case we'll name it "Vondelgnomes":


Next, we'll draw the areas. To do this we have to select the 'shape' tool, which is a subtool of the line tool:


Draw the area in which you want media to be triggered. When you finish your polygon a pop-up will appear asking you for a name for the polygon. it's important to give your polygon area the exact same name as the mediafile(s) you want it to trigger, otherwise the Treasuremapper software on your phone won't be able to find it. For example, here I've named this area gnome1 because I want gnome1.jpg to appear on the phone's screen and gnome1.wav to start playing when a user walks into that area:

When you're finished with your map press the save button.


Downloading the mapfile from Google

Now that the map had been designed, we need to download if from Google. Google maps wasn't designed to allow this, but it's easy to do..
First, while editing, click on the Link icon, and copy the URL google provides. Add the following at the end of the url: &output=kml and then open it. Your map should now download.


Place the Treasuremap in a folder that has the same name (this is 'case sensitive', and please use _ instead of spaces). Also put your mediafiles in the folder. Congratulations: you have now finished your Treasuremap.

Next step: get it onto the Nokia phone.


*Tip: if you do have mobile internet you can just click on the "view in Google Earth" link, and then asked what to do choose "save file". You have now downloaded a "NetworkLink" KML file. This file doesn't contain the trigger areas, but it contains a link to a file that does. If you place this on your phone Treasuremapper downloads the actual triggermap from Google Maps when you load this Treasuremap on your phone. This can be fun, because it allows you to change the map online, and have it automatically update on your phone. Perhaps you can make a day-time and a night-time map? In a future version you could even download the latest map not just when Treasuremapper starts, but every 10 seconds after that. That would allow for interesting live interaction between a mapmaker and someone in the street trying it out.
