If you're on the Isle of Man (or thinking of visiting) and you have an iPhone or iPod Touch, you may be interested in the latest mobile guide to the Island that's been released for the iPhone.

I blogged last year about a couple of specialised iPhone apps that let you see offline maps of the Island - but not much more - and I also mentioned OffMaps which at the time was simply an offline map viewer that let you download maps of anywhere in the world. Having released their latest version though, OffMaps now provides much more functionality in the form of a local guide to businesses, services and attractions, and access to Wikipedia articles about the places around you.

Now, if you're looking for a bar, cafe, restaurant, museum, tourist attraction - or, in theory, anything else - you need look no further than the guide in OffMaps. It'll show you its location, give you their address and phone number (though there aren't many of these yet) and link you through to their website if they have one. Note that not everything is in there, and in particular it's lacking in the shops it covers, as well as in some other areas.

If you run a business or service - or know of one which isn't already covered - and you'd like to advertise yourself in this guide to the Island, you can be a part of it for free.

All of the information is based on the OpenStreetMap project and Wikipedia, so you can add your information yourself. The easiest way to edit is using the free Mapzen POI collector app for the iPhone, but if you're not comfortable, just drop me an email and I'll happily add your details in to OpenStreetMap for you, for free, and you should get into the guide the next time it gets refreshed.

Note: the app is currently only listing things in certain chosen categories, so if your business falls outside of those categories it may not show up in the guide. You're still free to add your listing to OpenStreetMap though, as it could be used in the future either in OffMaps or in any other application.

As I'm sure you know, there have been numerous innovations in the world of geography online in recent years, from Google Maps to OpenStreetMap, FireEagle to Twitter, and many more, but most (if not all) of these developments have come from commercial or open source worlds with little support from the public sector - unless you had access to large amounts of money to pay for their data.

The British Government is now starting to see the benefit of opening up data though, and I'm particularly happy to see the Ordnance Survey looking to make more data available to the public. All of which should stimulate innovation even further as it starts to make information available that was previously locked up in only commercially available datasets.

Related to this overall effort, the OS is currently promoting their GeoVation Challenge to encourage people to share their ideas for geographic innovation. There is even money up for grabs for the best business ideas proposed, designed to help get those ideas to market.

So, if you have ideas for map-based or generally geographic things you'd like to see developed, but don't have the time or knowledge to do it yourself, you can share them in the GeoVation Ideas Challenge and be in with a chance of a tour around the OS headquarters in Southampton (an interesting visit if you get the chance). On the other hand, if you have a business idea, and are prepared to put the work in to get it going, you can share your idea in the GeoVation Awards Challenge and be in with a chance to win up to £10,000 to help get your venture off the ground.

If you're interested in taking part, you will need to act fast as the closing date for entries is 4 January 2010. Best of luck!

After two years of working from home, I've decided it's time to make a move back into an office and look for some contract-based or perhaps permanent work in London.

I have four years of experience using, developing and helping guide the development of Drupal projects as well as a background and interest in all things geographic, from maps to open data (as you've probably seen from the topics I cover in my blog). With these skills I am looking to find some work as a Drupal developer for an organisation based in London, ideally integrating my geographic interest. Alternatively, I'm open to other opportunities that I may be suitable for.

If you have, or know of, any positions coming up from January onwards, I'd love to hear from you to discuss the details. You can find out more information about me in my CV (pdf) or on my LinkedIn profile.

There are a number of iPhone apps - such as OffMaps - which let you use OpenStreetMap data, and view the maps, on your iPhone and iPod touch, but there hadn't been any apps which let you edit the data, until now.

If you are a member of the OpenStreetMap community, you've probably been out and about at some point and looked at something and thought 'hmm, I wonder if that [insert interesting thing here] is already on the map?'. Well, now if you have an iPhone you can quickly check whether it is or not, and either add it or update its details directly in the OSM database.

The first iPhone editor to launch on Apple's App Store is Little OpenStreetMap Editor (iLOE), an app that allows you to add or edit OSM nodes wherever you are. While its user interface isn't very friendly at the moment, hopefully it will improve in the future and make it easier for users to edit the data around them. In the mean time, it does do the job, so if you're desperate to edit OSM on the move, give it a try.

Cloudmade are also working on an app - the Mapzen POI Collector - which aims to give a quick, user friendly way of editing OSM data. The app tries to make it as simple as possible to contribute to the project from your iPhone, whether you were an OpenStreetMap contributor before or not. The only thing you need to do is sign up for an account at openstreetmap.org, and the app will let you add all sorts of information without having to know anything about the tagging scheme used in the project.

Currently awaiting moderation to get into the App Store, the app should be available very soon, and is definitely worth trying out when it's available. If you're interested, you can sign up to be notified when it's out. I've tried out some pre-release versions which have been shaping up very well, as these screenshots in their tutorials show.

A number of apps are available on other mobile platforms which will let you view OpenStreetMap data, and a few of them also allow editing, including the Java-based TrackMyJourney app which I recently tried out on my Nokia N95 phone.

Update (26 November): Mapzen POI Collector is now available for the iPhone from the App Store

I've been back in London for almost two years now and haven't met that many people working with Drupal, partly due to working from home I think, but also because there don't seem to be too many events (outside of paid training events and the like) that are aimed at Drupalers in the London area.

As I was looking today to find out if there were meetups happening already that I wasn't aware of, I came across a thread on groups.drupal.org asking about regular meetups, and left a comment to say I'd be interested if there was anything happening. In a city the size of London, there are surely enough people working with Drupal to get a group of people together every now and then for a social event. I for one would love to meet more people in the area who are working with Drupal, and maybe have a pint or two in the process.

By the end of the day, there was a meetup organised: London Drupal Pub Meet- September Meetup. Brilliant!

If you're interested in coming along, sign up to the meetup.com event, and I'll see you there!

edit: the event will be held from 7pm on Monday 28 September, at the Square Pig, Holborn.

Since I received the DVD of high resolution aerial imagery and maps from the Isle of Man Government last week, I've spent most of my spare time starting to digitise information for the OpenStreetMap project.

Using QGIS to load in the data, I started to gather all the names from the map that I could, including both place names (for small local areas, hamlets and villages that weren't already in the database) and also farm names. With over a thousand names, this is already a massive boost to the data in OpenStreetMap as it is data that would have been immensely difficult to gather on the ground.

The image to the left represents the shape of the Island, made up of all the points obtained from the map, and soon to be imported into the main database.

The three images below are of small areas that I have started to digitise the buildings of. I'm offering a prize (a pint at the next London mapping party perhaps) to the first person to guess all three places correctly. Two of them may well look familiar to anyone who I chatted to at the 5th birthday party of OpenStreetMap.

Most of the data in the images above (and future data others would like to extract for OpenStreetMap) would have been impossible (well, certainly extremely impractical) to gather were it not for the very generous support of the Isle of Man Survey in giving us a license to derive this information, for which I'm personally very grateful, and I know a lot of other people in the project are also excited about.

These images are licenced as CC-by-SA and the data behind them all will be in the OpenStreetMap database very soon.

Before traveling back to the Isle of Man for the second Manx mapping party, I received an email from Juan Watterson, the Member of the House of Keys (MHK) responsible for the Isle of Man Government's mapping efforts (as part of the Department of Local Government and the Environment) who was interested in OpenStreetMap and in particular the Isle of Man mapping project. Juan kindly put me in touch with the Government's Senior Cartographer, Rob Clynes, with whom I met up when I was on the Island.

Back in 2007, Rob offered Nick Black the use of the official 1:100,000 small scale map of the Isle of Man from which to gather data for OpenStreetMap. Since then, CloudMade mapped the Island more thoroughly than we had done previously, and donated their data. While that gave a massive boost to the map data for the Island, there was still plenty more information which could be added to the map, hence the recent mapping party.

Meeting with Rob, he talked me through me some of the work he does, like digitising high resolution aerial imagery, change monitoring, co-ordinating the updates of the imagery, and cartography for the smaller scale maps (1:100,000 and 1:25,000) they produce - largely as a side product - and turn into printed maps. It was interesting to compare the data collection and management processes they have with those we use in the OpenStreetMap project, comparing my Walking Paper scrawls and GPS tracks from the weekend before with the official map data creation.

Having chatted with Rob for a while, he mentioned that he should be able to sort out some more data to help out the OpenStreetMap project. I got home yesterday to find a DVD of geodata sitting on my door mat. We now have access to two datasets from which we can derive data for the project:

• the 1:25,000 tourist map (2007), provided as a set of four GeoTIFF images
• the high resolution aerial imagery (2001), provided as a set of three MrSID images

OpenStreetMap	IOM Government 1:25,000	IOM Government aerial imagery	using overlays

There is a massive amount of information which we can gain from these datasets still, and I will be posting some ideas soon about different possibilities, such as collecting place names, paths and tracks, historic sites, outlines of the national glens, open rambling land, etc. as well as using the data for error checking and correction in the existing OpenStreetMap dataset.

I am planning to make these datasets available as a WMS server that can be used in JOSM (and Potlatch) for editing, once I've had a chance to organise it, and have had an official license document through.

If you're interested in helping collect data from the data to add to OpenStreetMap, please leave a comment below or get in touch.

In just two weeks time, on Saturday 1st August 2009, I am going to be organising a mapping party in Douglas, Isle of Man for the OpenStreetMap project. The aim of the project is to build up a map of the world that can be used without the restrictions that are typically imposed by mapping providers such as Google Maps.

The Isle of Man already has a great amount of map data in the database - as you can see on the map at openstreetmap.org - so we have a good starting point, but it isn't yet complete, so there is plenty of information that we can still add. While the road network is very close to complete, we are missing many of the points of interest you might like to see on a map, or be able to search for (perhaps through a website, or in the future from your in-car navigation device), like pubs, cafes, restaurants, libraries, hotels, historic sites or museums, for example.

We also have some Manx names for places and streets, but this isn't yet widespread, so it would be great to capture this information from street signs around the town.

As we have a good street network already, the need for a GPS isn't as important as it was earlier on in the project, so the plan for the mapping party is to use printed maps (from the excellent Walking Papers project) onto which we can add annotations during the day. At the end of the day, we can use the paper maps for reference when entering the information into the map through the OpenStreetMap website, or scan them in and deal with them later, depending on how tired people are after a day's mapping.

If you're on the Isle of Man and interested in making or using maps (or just the underlying map data), then do come along and find out more. If you're also interested in a little exercise, come out with us and explore Douglas for the day, collecting information to add to the map. You can find out more on the OpenStreetMap wiki, or alternatively contact me if you'd like more information.

If you run an organisation on the Isle of Man which uses geographic information (e.g. business listings) and would like to find out more about including your information in the map database so they can be displayed on the map, or would like to use the maps on your website with your own information displayed on top, please get in touch.

In September, the Society of Cartographers is going to be holding their 45th annual Summer School event in Southampton.

It's interesting looking through the programme to see just how much of the event is about data, and much of it coming from sources that didn't exist just a few years ago, from OpenStreetMap, the new UKMap and of course the various Ordnance Survey datasets that are available to organisations who can afford to pay for them.

I wonder how the content of this annual summer school has changed over the years since it started, as more and more data sources have become available for cartographers to use?

If you're in the UK and are interested in making maps, the event (7-9 September) looks like it will be a good place to see where cartography is heading, get some hands on experience in the workshops and also network with others in the industry.

I was looking recently to see what applications were available for the iPhone (or iPod touch) relating to the Isle of Man, and was pleasantly surprised to see that a mapping application had been released.

The application, simply called 'Isle of Man', gives users a map of the Island for use on their iPhone while they are visiting. In addition to the map, it lets users find amenities and streetnames that have been added into the OpenStreetMap database. I decided this morning to pay the 59p to download the app and try it out, but beyond the initial excitement of seeing OpenStreetMap data being used for mobile maps of the Isle of Man, I haven't been so impressed with the execution of the idea for a number of reasons...

The Mobile-Streetmaps.com website promotes this app and hundreds of other similar ones from around the world, each just a download of OpenStreetMap data packaged into an application, for which they charge 59p. While it's not a large amount to pay, the company producing the applications is profiting off the generosity of the OpenStreetMap community (and in the case of the Isle of Man, Cloud Made as well, thanks to their donation of data) with little attribution, and no mention within the app itself of the license under which the data is available.

Hopefully the company will fix the attribution issue soon, by adding a mention to the pages in the iPhone app store that the data is from OpenStreetMap, and also by adding information about the license to at least the about page of each app, and to the side bar of the pages on their website.

The app itself could be quite useful if you're visiting the Island, but it has quite a few usability issues that hamper its use:

• Zooming in to the map, you are not shown beyond a certain level, leaving many streets in the center of towns and villages left without names.
• Navigation within the app could really be improved... there's not even a back button to get back to the map from various other screens.
• After searching for items, you're taken to the map, but you are left looking at the place you were looking at before, with no obvious indication that pins have been added to the map outside of your current view.
• There is no way of clearing the pins from previous searches from the map, leading to possible confusion when searching for other things.
• Clicking on the pins for search results doesn't give any more information to the user. It would be nice to be able to get contact details where available, what the nearest street is, etc.

If you would like to access maps offline for more than just a single place, and be able to take advantage of recent updates to the maps, you will probably be better off downloading the OffMaps app which I have yet to try, but costs just a little more at £1.19 and lets you choose the area and level of detail you wish to download, and lets you do it for as many places as you wish.

While free and open geodata from OpenStreetMap gives a great boost to these applications, it also has its downfalls in that it's likely not (yet) complete for any given area. To give an example, searching for 'cafe' amenities in the Isle of Man resulted in just the Silverdale cafe being shown on the map, where in reality there are many more cafes that aren't (yet) listed.

To help improve the amount of data in the Isle of Man that's represented in OpenStreetmap, in particular relating to points of interest (POIs), I'm planning to hold another mapping party on Saturday 1st August. I'll post more information about this soon, but put the date in your diary if you're interested in helping put some of these amenities on the map. If you'd like more information in the mean time, please get in touch.

Update: having contacted the author of the apps, he's already been working with the OpenStreetMap community and has agreed to improve on the attribution, which is good. I also tried out OffMaps and liked it, but one thing it doesn't give you that the individual place-based apps do, is the access to find the location of POIs and streets while you're offline (though it does work when online).
