This past weekend saw the annual OpenStreetMap “State of the Map” conference arrive in Girona, Spain. I attended for the fourth year running and was glad to be given the opportunity to talk about mapme.at, what it is and how it uses OpenStreetMap data.

I started by giving a brief overview of the site, the functionality offered and how we integrate with many other services. I then went on to describe mapme.at as a “Social Location Experimentation Platform”. My idea behind this concept is that mapme.at gives people many ways to experiment with their location. On the one hand it allows regular users to experiment by trying out various services that become available. As an example, someone might decide to try Google Latitude out, perhaps as they’ve just got a new android phone. After a few weeks this person might decide that latitude isn’t offering what they want, perhaps they prefer the badges and mayorships of Foursquare. If they’ve signed up to mapme.at they can store all of their locations in our database where they will be available to the user to download or use in the future. In this way users can experiment without having to think “there’s no point trying this service out as I’ll just stop using it after a few weeks”.

The other type of experimentation is developers experimentation. Developers can use our API to experiment and produce all sorts of great apps. I mentioned the ferry trackers as an interesting example of putting data in, and then the “Weasley” clock as a fun example of pulling data out.

I also discussed some new functionality that we’re hoping to launch soon. Currently though we use OpenStreetMap as our canonical source of place data, there’s actually three sources that places might come from. If you’ve been using OpenStreetMap since before we launched the places functionality you may have added favourites for places you went to. Many of these favourites are public places that are now covered by the OpenStreetMap places. Part of the new functionality will allow you to merge your old favourites with the OpenStreetMap places meaning you’ll have a single set of logs all attached to the same place. If you’re using Foursquare you may have noticed that we do try to match their “venues” onto our places. Sometimes this isn’t possible though and if you’re using both mapme.at and Foursquare to check in you’ll sometimes find you’re logged at two separate places. The second part of the new functionality will allow you to manually match Foursquare venues onto our places so again you end up with all your logs attached to a single place. The result of this piece of functionality should be a big database of mappings between Foursquare venue IDs and mapme.at place IDs, and by extension OpenStreetMap IDs. We fully intend to release this data when it becomes available and we think this will be a good useful dataset for many people.

If the talk sounds interesting you can find my slides on slideshare or see them above. I believe all the talks were recorded too so videos should go live eventually. I’ll finish off by thanking the people who organised the conference. It really is one of the best conferences covering location and all things geo and they really did a good job of pulling everything together. The only thing left is to ask where will State of the Map 2011 be?!

We’ve still got some things to finish up to complete the support but right now you can go to your Sources page and link your account to Foursquare there. You have three options for how we’ll work with your Foursquare account. You can choose to let us pull your location from Foursquare which means that all your check ins get pulled into MapMe.At. Where possible we’ll match the Foursquare Venues onto our own places but where that’s not possible we’ll create an entry on our site to allow you to show people exactly where you are. You can also choose to make your “shouts” visible so people can see what you were doing when you checked in.

We will be adding support to push your locations from MapMe.At back into Foursquare soon so if that sounds good, just check the box when you link your account and we’ll start pushing locations over as soon as that’s ready. Again when we push locations into Foursquare we’ll try to match our places onto theirs where possible.

If you have any problems let us know over on Get Satisfaction or by mentioning our twitter account.

Great New Look and Feel

For our new design we enlisted the help of the great team at Cogniance. They worked with us to provide a new logo and overall look and feel. They also gave us some ideas for improvements to the user experience; many of these have been implemented already but some are still on the list to be completed soon. We’re really happy about how the new look has turned out, the bright colours really inject life into the site and the fact that we’ve been able to tie these in with the map is just amazing, more on that in a moment…

CloudMade Integration

So far we’re taking advantage of just a few of the great services that CloudMade provide. In the previous section I mentioned the fact that we have been able to link our colourscheme into the colours used in the map. This is possible due to the groundbreaking new “Style Editor” tool from CloudMade. With this you can edit the styles used in the map to your heart’s content. Our map style was based on one that CloudMade call “The Original”, this looks really nice and only required us to spend a short time playing with the style editor to get it coordinating with our colours.

We’re also using the Geocoding services that CloudMade provide. Geocoding is the process by which a computer takes a written address, such as “10 Downing Street, London” and converts it to a latitude and longitude. We use this service on the homepage to make it easier for you to find your current location and create favourites, and with the twitter integration when you’re out and about. We’re really happy with the results we’re seeing from this service and we know that CloudMade are working hard to make it even better.

By using the unique OpenStreetMap dataset CloudMade are able to provide some really good services giving us access to the data at a very low level. We’ve got some ideas for how we can more closely integrate them into the services we provide on mapme.at and you should see these developing over the coming months.

You may notice that OpenStreetMap and therefore CloudMade do not have street level coverage worldwide. It’s actually the case that no mapping provider currently has coverage throughout the world and, similar in some ways to those providers, OpenStreetMap has some areas with better coverage than others. The one big difference is that if you find that the coverage around the locations that you visit often is lacking, you can get involved with improving this. We at mapme.at are big fans of the OpenStreetMap project and have been contributing for a number of years. We whole-heartedly recommend that you get involved, you might want to try signing up to their mailing lists or just take a look through their “wiki” to find out how to get involved.

New OAuth Developer API

At mapme.at we’ve always tried to make it as easy as possible for you to update your location. We already provide integration with Twitter and with FireEagle. You can update your location through the web, via email or even using DNS. So far though all of these integrations have required us to do most of the work on our side, meaning that you couldn’t use a new method, such as a new mobile app, until we had done some work integrating it. We are now opening up an API (Application Programming Interface) so that any developer can sign up and integrate their application with the mapme.at site.

An API is essentially a set of instructions and methods that we give to developers that tell them how to access our website and update the data that we store here. Obviously it wouldn’t be very good if just anybody could access all the data we store, or change everybody’s data so to stop that we use authentication. We’ve decided to use the OAuth authentication scheme to make sure that we take the best possible care with your data, while allowing you to make the most of third party services that will enrich your experience of mapme.at. OAuth allows you to give permission to a third party service to access or update your data on mapme.at without you needing to give them your username and password. This means that if at some point in the future you decide that you don’t want this service having access to your data, you can simply revoke that access from our website. If, for instance, you gave a mobile app on your phone access to your data, and then lost your phone, you could still revoke the access even though you can’t use your phone.

If you’re interested in trying this out then you can find the documentation about our API here. We’re just starting out with this so we’re declaring that our API is currently in “beta” mode. This means that we’re still working on it and the way it works is likely to change in the future, we’ll try to keep you informed in advance of any major changes though. We’ll also be working to extend the documentation further to cover more aspects of the API.

one more thing… iPhone!

The final thing that we mentioned in the talk at CloudMade is that we’re currently working on a native iPhone app to really simplify use of the mapme.at services on the iPhone. It will use our custom map tiles so will look really good, and will allow you to update your location, see which of your contacts are nearby and continously track your location. It’s still going to be a few more weeks before it’s ready but as soon as it is, we’ll let you know!

As you can tell there’s been a lot happening recently with the mapme.at site. The development doesn’t end here though so we’ll be continuing to add new features over the coming months. We’ll also be extending the documentation not just for the new developer API but also the documentation for the site in general. Finally we’ll try to keep you more in the loop by keeping this blog active, so sign up with your favourite RSS reader to make sure you hear it about it straight away!

I find this a very interesting story to follow. Though The Box travels quite slowly, and therefore is not something to follow on a minute-by-minute basis, it will end up travelling long distances and should create a thorough map of the busiest shipping lanes and ports throughout the world. As such it’s certainly something I will be keeping an eye on. I thought it might be useful to have an Atom feed with GeoRSS to make it possible to follow the path of The Box without having to remember to check the site. I was also quite interested in creating a user account for The Box, pulling the location of it into mapme.at and allowing users to follow the location on this site. Fortunately I can now announce that both these things are now possible.

I’ve put together a basic script that pulls down the location of The Box every half hour and places this into the mapme.at database. The username is “thebox” so you can see its current location at http://mapme.at/where/thebox. I’ve set the permissions on the account so that anyone and everyone can view its location, but if you add it as a contact then it will show up on your homepage if you ever happen to be nearby.

You can also follow the path of The Box by using a new feature of the site. The following URL will return an Atom feed for the user “thebox” for all logged locations since midday “yesterday”:

http://mapme.at/api/where.atom?username=thebox&since=yesterday&mode=since

This next URL will give all logged locations since The Box was launched on the 8th September:

http://mapme.at/api/where.atom?username=thebox&since=2008-09-08+00:00:00&mode=since

If you use this in a standard RSS reader such as Google Reader or Thunderbird you’ll find an entry for each location that the box has been to, a small map of the area and a link to the history page for that day. If you load the RSS file into something that can read GeoRSS you’ll see a map highlighting all of the places it’s been to, for instance here’s the link loaded into Google Maps. Loading it in a standard RSS reader is a good way to be kept up to date about when The Box moves without having to look yourself.

As you might have guessed, you can also use this URL to track your contacts, though at the moment you will only be able to do this if their location is open to the public. More features along these lines should be coming soon!

As mentioned in the previous post, mapme.at aims to make it as easy as possible for you to keep a complete location history. If you’re a regular twitter user then a really convenient way to do this is to send your location out whenever you twitter. By simply placing an address or the name of a favourite in brackets before your message you can tell twitter where you are. It’s unobtrusive, and it generally doesn’t hurt to tell your twitter friends whereabouts you are (especially if it makes them jealous!)

Getting mapme.at to read your twitter updates is very simple. You will need a twitter account so if you haven’t got one already then you’ll need to head over to twitter.com to sign up.

Once you’ve got a twitter account head over to your Location Sources page on mapme.at and scroll down the page until you see the Twitter logo. Enter your twitter username in the box provided but also take a look at the checkboxes and the different options for how you can update your location via twitter. By default all three should be checked allowing you four different ways to update your location via twitter, if you have a habit of sending messages with bracketed prefixes, or just don’t like how we geocode your messages then feel free to uncheck some of the options. Once you’re ready click “save” and we should begin reading your messages. Our twitterbot will only check every 5 minutes, but if you’ve sent multiple messages during that time we will notice and log them at the correct times in your history.

Twitter was actually used as an example in the first mapme.at blog post of something that you would like to geotag. When sending twitters myself I usually like to make sure I have already stored my location so that I can tie the location in at a later date, but this method allows you to tie the location right into the twitter itself. If you don’t like the idea of telling your friends where you are in every twitter, but you like the idea of the convenience of using twitter then a direct message should be right for you.

There are lots more ways to store your location so come back soon to find out more.

Setting up Fire Eagle is pretty easy to do. You’ll want to start by heading over to the Fire Eagle website to sign up for an account. Once you’ve created your account on Fire Eagle you’ll need to come back to mapme.at and go to your “Location Sources” page (labelled “Sources” on your homepage). Scroll down until you see the fire eagle logo and you should see a link labelled “Click here to authorize your FireEagle account for use with mapme.at”. Click on that link and you’ll be taken to the Fire Eagle website and be asked whether you want to allow mapme.at to update and access your location.

We recommend that you allow mapme.at to both update and read your location, and that you give us access to your exact location. You can then use our controls to allow your contacts to have different levels of access. Whether you do this or not is up to you of course.

If you agree to let mapme.at access your location we will ping Fire Eagle around every 5 minutes and ask them for your location. If it’s changed since the last time we looked, we’ll store it in our database. Also every time you update your location on our site, we will let them know (if that’s what you have requested).

Having support for Fire Eagle gives access to a huge number of services for updating your location, take a look at the Fire Eagle Gallery to see which ones are useful for you. Not all services are compatible with Fire Eagle though, and some are unique to mapme.at. I’ll be posting a few more blog posts telling you about more of these methods over the next few days.

The main way to expose your location to people within mapme.at is to create a list of contacts that are also using the site. Currently there is no search mechanism for finding people so you will need to find out their username through some other means – twitter, email and instant messenger are great ways for communicating this information with people (ok, maybe a search function would be good, coming soon…)

Once you have the username of someone you want to share with you’ll need to login to mapme.at and look at the contacts tab on your homepage. You should see a simple form with a box for the username and then a few choices for how you want to identify the person. Now for the important bit:

MAKING SOMEONE A CONTACT MAY ALLOW THEM TO SEE WHERE YOU ARE

This is very important to realise. mapme.at is all about sharing your location. This is a great thing and has many uses, but you may not want everyone to be able to find out your accurate location. Please think very carefully about who you share your location with. We’ve given you three options to allow you to filter people, if you’ve used flickr before you will have seen something similar. Some photos may be just for friends, some for family and some for everybody to see. In the same way mapme.at allows you to give friends, family, other contacts and the world at large access to see your location to different degrees. Think carefully before deciding which group you want to put someone into. Other contacts can’t see what group you’ve put them into so hopefully they won’t be offended (though they will be able to tell what accuracy level they can view your location at).

Once you’ve decided what group you want to put someone in you need to enter their username and select the correct option. Click on the button and you’ll now be in contact with that person. They will be sent an email to inform them of the fact and be given the option to get in contact with you too. Be aware that at this point you have only given the other person the ability to see your location, you will not be able to see their location until they make contact with you. You will also need to set your permission levels, read on to find out more about that.

When you sign up to mapme.at initially, the default settings don’t allow anyone to see your location. To alter these settings and share your location you’ll need to go to the contacts management page, here you’ll find entries for each of the groups that you can assign contacts to, and one for the general public, and settings that modify the amount of access you’re giving that group. Modify the settings to suit you and click “Update” and you’re ready to share your location with people. Be aware that if you modify these settings they apply to previous locations that have been stored. If you open your privacy settings for a specific trip, people may still be able to look into your history to find places you’ve been previously. In the future we’ll be looking at improving this mechanism but for now be aware of what you’re doing when you make changes.

Now you should be all ready with a few contacts and be able to see where they are. Notice that contacts show up on the map on your user homepage so that you can see who is around you at any time, you can also drag the map around and it will update to show contacts in the area you’re looking at. If you want to see where someone has been previously you can take a look at their history page, you’ll find this at mapme.at/where/<username> – or simply click on their name in the contacts section on your homepage. If you’ve set your privacy level so that members of the public can see your location then they’ll also be able to use that URL to track where you are.

This blog post may come across as quite serious, all this stuff about “be aware of what you’re doing” may seem over the top. At mapme.at we’re really concerned about privacy and want to make sure we don’t confuse you and cause mistakes to happen. As mentioned above we’ll also be adding more features in the future to give you finer control over what you share and what you don’t. Keep an eye on this blog for future updates.
