What Tools Do You Need to Develop an LBS Application Part 3
Geocoding and Reverse Geocoding are key components for many LBS Applications.
Geocoding is the process of generating a set of co-ordinates, which are subsequently used to display a location on a map. If you have a huge database of addresses, we typically do this as a batch process and have tools designed to try to compensate for poorly laid out databases, or errors such as mispelling, wrong suburb or when people like Real Estate Agents make up their own to make a location sound more attractive. A common one for example is Whangarei Surrounds. There is a place called Whangarei, but not Whangarei surrounds. Computers being fairly literal, if you try to search for a place that doesn’t exist in the database, you have to get creative.
Services like the POI Webservice V2, whichwas mentioned in the previous blog, are designed to help you with this requirement. How you do this depends on the type of application you are developing. For example:
- If you are using an SMS service, you would have to have a very good address, if you want to get a good result. If the address doesn’t exist in our database, we can return a set of co-ordinates that are next best, for example if we don’t have the exact street address, we can return the middle of the street. One common issue in New Zealand which dates back to the days when we had lots of councils who didn’t consult with each other on street name allocation. As a consequence of this there are many duplicates. For example there are 23 different Queen Streets in Greater Auckland.
- An autocompleter is a great way of getting to the correct address first time. You can see a nice example of this on AA Maps, where a new request is made of the POI Web Service every time a new character is entered, if the right result comes up at that point, you can click on it and then perform the action desired, such as viewing it on a map. This can function easily in a PC browser and can work fine in many mobile browsers. The main difference in a mobile would be that you reduce the number of results displayed in a list to make it user friendly on the smaller display.
For developers, there is much more detailed information in the Developer Section of our web site, including code examples. We support a wide range of results from text to javascript and html.
Reverse Geocoding is a powerful tool for mobile devices. What this does is using the co-ordinates derived from the mobile phone, we can display the users current location on a map. What we can then do is provide information about Points of Interest close to the user.
The first thing we can offer is the nearest street address. This can be used in various solutions such as
- Buddy Finder
- Locating children or elderly people, to ensure they are where they are supposed to be. This can include things like geo-fencing (which will be explained in a future blog). The concept for children or elderly people might be to make sure they are at school, or perhaps close to the home or retirement village. It is very common for elderly people with Alzheimers or other conditions to wander off and then lose track of where they are or how to get back. Reverse Geocoding could enable authorised people to find out where they are if they have gone missing. Geo-fencing allows you to create a ring or polygon around the area they should be at, for example the gardens and surrounds of a rest home, but set of an alarm within a system if people leave that area, or go within a predefined distance of that area.
- Locating people for health purposes. For example a system in Europe was designed to locate people such as diabetics who are away from their home and don’t have their insulin with them. Reverse geocoding could locate exactly where they are, while a proximity tool could identify the nearest Pharmacy which could prepare are dose and put it on a taxi to the patient’s location, even if they are disoriented and not sure where they are themselves.
This leads on to another benefit of reverse geocding in mobile applications. One of the most common services being developed for mobile applications is the ability to find Points of Interest nearby the location of the person’s mobile, without them having to be able to identify their location. This would then utilise either a proprietary database, or the GeoSmart subscription POI database which was mentioned in our previous blog. We have an extensive database covering most locations you might want to find when you are out and about. It could be (follow the links for examples on AA Maps web site) a motel, BP petrol station, a public toilet, a National Bank ATM, a pharmacy, cafe or pretty much anything. This makes it really for people to find anything they need within proximity of their location, without having to kow where they are.
Proximity Based Marketing will be a huge growth area for LBS which is enabled by these tools as is Location Based Social Networking.
Of course if you now have the co-ordinates of where you are and the co-ordinates of the location you want to go to, you can now offer turn by turn directions to that location n the mobile. This will be the topic of our next blog, so if you are interested in this subject, please bookmark this blog, or add it to your RSS aggregator such as iGoogle.
Geocoding and reverse geocoding a critical tools for mobile LBS applications.
What Tools Do You Need to Create a LBS Application Part Two
One of the key things people want in an LBS application is to be able to find Points of Interest (POI) including geographical, community and business POI.
GeoSmart has collected and continues to collect information about all the places that people would like to visit, and unlike other databases, includes a lot of information that has importance but isn’t necessarily business related. For example beaches and bays, public toilets, boat ramps, parks etc.
Our latest service is called the Point of Interest (POI) Web Service V2. We have full time staff focussed not only on collecting quality spatial information about places you might want to find for an LBS Service or Application, but also making sure that it is current. Where relevant we use ANZSIC Codes which are a standard supported by the NZ and Australian Governments. These offer a layer of categories from high level to more specific, so you can look at food and beverage or Italian Restaurants at either end. We have a browser tool to help you find the correct category here.
Our comprehensive database which is used in various forms and subsets on websites such as AA Maps, Bayleys, Winejobs Online and many other sites has a wide range of POI. These include shops, petrol stations, banks, ATMs, schools and where relevant, make sure you get to the right place at the Point of Interest. For example if you are going to a hospital, you probably want the Accident & Emergency entrance. If you are going to the golf course or a school, you want the official entrance and so on. Our data, where relevant includes information such as contact details.
The POI Web Service can also be used for geocoding street addresses in order to display them on a map, using our geotagged web map tiles, which can be used on a mobile or normal PC browser. We have a comprehensive database of New Zealand street addresses, which you can try out on the AA Maps website, using our autocompleter.
The range of parameters are wide and varied and you can find more information in the Developer Page.
A key commonality in successful LBS applications overseas is the ability to find the service you are looking for nearby. For example, you are in the city and want to find a nearby cafe for some lunch. The POI web service would let you specify how close you want to find one and even give them to you in order starting with the closest to you. Our POI database is also used in products such as TomTom and Navman car navigation devices.
Because the database is very comprehensive and constantly growing and being validated, you can pretty much develop your application and populate it with our data and be up and running in no time.
Another service that we offer in conjunction with the NZ Automobile Association is the AA Maps Bizlocator. This is a free service which allows any New Zealand business to register their location with us and at the same time get a free web map to put on their website to show people where their office, shop or other business location is, assign it to ANZSIC Categories and then be available for addition to our POI database, all for free. The only condition is you have to go online at least once a year to confirm that your data is current. Once the map is up, you can even get and print turn by turn driving directions from anywhere in NZ and print them neatly on A4 paper. All for free. For more information on that please go to this page, where you can set up an account and ‘Add Your Business’.

Location Based Services and Agencies
Now that the Awards are over, at least for a few months, I’m hoping to have a little more time for blogging.
I have been talking to a number of agencies over the last 3-4 years about LBS. I don’t know whether it was me or that the bright lights in this agency space seem to all go offshore, often within the same company before we get to do anything together. Companies like The Hyperfactory have been doing some cool things on the edge of LBS, but it seems that all their cool stories these days are also overseas. It was great to see them enter the awards this year, though and they have a Finalist Award to add to their trophy room which must be bursting at the seams.
The types of LBS applications are very wide and we could have had many more categories in the awards. The thing is that location is simply what it sounds like. It is about where you are and what you are doing wherever you are. It could be about having a pizza delivered to you on the beach, or about catching the bus to Get Somewhere. It could be about going on a treasure hunt or finding a bar or cafe nearby afterwards. Location is ubiquitous, just as your mobile phone is. You are always somewhere. If your phone knows where you are, then it can help you find things, places and people. It can help you be entertained, help you with your sport or hobby, provide you with localised information, the list is infinite.
So back to Agencies. LBS adds another vehicle to incorporate into Marketing and Advertising Campaigns. It gives them the opportunity to come up with fun and compelling ways for brands to interact with consumers and other customers at the time and place that has the most relevance. Traditional forms of advertising are very often scattergun and rely on high levels of repetition to realise a call to action. Traditional Direct Marketing (DM) considers 5-7% response to be a good result. In my book that says that over 90% of the DM spend is wasted. Why is that? Because most people are not open to buy or looking for their products at the time they are ‘exposed’ to the promotion. In addition to that, most people are smart enough to look for what they want, when they want it. They will then either check out their favourite stores or use Google to find the products they want.
The other huge resource that people use is Word of Mouth Marketing, which these days means talking to people close to them, or just as likely today, to use Social Networking sites to ask the opinion of their ‘friends’.
So what can agencies do? They can come up with campaigns or solutions that are relevant to people’s interests at the time and place that is relevant to them. The time and place to tell someone about the great new winter fashion that is in their favourite clothing store, is when they are entering the mall. The time to tell people about the new Stephen King book is when they are near the bookshop.I’m going to talk a lot more about these concepts in the coming days and weeks, so why not subscribe to this blog with your favourite RSS aggregation app like iGoogle.Just to put things straight, LBS is not something that will replace other forms of marketing, it will augment the campaigns, reinforcing the messages and making them relevant and encourage an immediate call to action. It is an enabler and a tool that will help brands fine tune their target marketing and improve its effectiveness.
I will also explain in future blogs how the tools and data that GeoSmart Maps has, can facilitate the creation of the applications or features of LBS from a laymans persepctive. I’m not a developer, but what I do understand very well is what each tool does and how it can be implemented to achieve the results you want. So if you want to know more, watch this space, bookmark it or get yourself an RSS Reader.

Free V, Free Ice Creams, Free Entertainment and Location Innovation Awards
So I’ve been thinking some more about entries that people could come up with for the Awards. It’s summer Downunder and that raises some interesting ideas for LBS applications for the Awards.
In summer we have lots of events such as beach parties and concerts in parks sponsored by various organisations and often in conjunction with radio stations. Often as part of these events, ice cream and energy drink brands get together and offer opportunities to win free product and other goodies by getting to the right place at the right time.
This might be a game or a treasure hunt or it maybe simply a matter of telling people that there is a free concert on in a particular park or beach, or that the Outside Broadcast Radio Vehicle will be at a certain spot at a certain time and if you are one of the first (x number of) people to get there you will get some free product.
LBS is a great way to get people to head for those locations. Here are a few examples:
- Text a message to a short code with your current location (street address) and get the time and location of today’s beach party or concert, complete with personalised turn by turn directions on how to get there.
- Text a message to a short code with your current location (street address) and get your first, or next clue to get you closer to your prize.
- Text the name of your town to a short code to get information about the next event date and time.
- Receive a message that you can forward to your friends who you want to join you at the party or concert so they can also get their own driving directions.
- As above but with electronic coupons so that the first (x number of) people with the coupons get the prizes or free product. Only people who receive the electronic coupon qualify for the prize, which means people who send invites will want others to send one to them, which creates a viral marketing process.
Another concept could be a solution for free product for people driving on a holiday trip. This could be along similar lines, but promoting a different service. For example:
- In recent years the narrow Kopu Bridge leading into the Coromandels is a major bottleneck, sometimes with delays of an hour or sometimes much longer. On a number of occassions I’ve seen one of the distinctive V cars on the side of the road giving away cold cans of their popular energy drink to frustrated drivers sitting in a long line of traffic on a steaming hot summers day. If they are going to do that, they could come up with some sort of LBS traffic report telling people where the traffic jams are and where to find themselves a bottle of V to cool down with. Of course this would also be a great concept for brands like TipTop Ice Cream who frequent run summer competitions.
These are just a couple of ideas where popular brands can have some summer fun with LBS and Viral Marketing to promote their brands, show some technology leadership and appeal to the tech savvy Generation Y people and build some product loyalty.Maybe you could come up with an idea, win one of our awards and then sell the concept to them.
Location Innovation and Navball
How do you combine LBS technology with GPS and mobile phones with a gaming environment that is fun, educational and gives you plenty of exercise? That’s one of the questions we have for Kiwis who enter the GeoSmart Location Innovation Awards.
29 people have entered the awards so far and we know of several more people who are working on projects. A lot of interest has come from universities and we all know that university students love coming up with ideas for fun things to do. The Auckland City Flashmob Group already has 487 members who have signed up through their Facebook page.
In this blog I am going to give you some examples of applications that might gove you ideas on applications to create yourselves. One that I really like as a concept is Navball which comes from Amsterdam. The Netherlands are of course a nation of football fans and it makes a lot of sense to combine their love of the round ball game with GPS and LBS technology to come up with something that is fun, fast, competitive and very Generation Y.
The concept is that you have two teams of 11 players, just like you would in a game of soccer and they compete to kick a virtual ball into a virtual goal. The playground is a set of predefined streets, unknown to the players before they hit the field. The players off course have soccer strips so that they are recognisable from the general public and won’t cause concern for pedestrians as they go about their business.
Each player is equipped with a Nokia N95 which is GPS enabled. The players are shown where the ‘ball’ is and the location of the first ‘goal’. They have to form a line in the shape of an arrow in order to be able to identify the direction the ball will be kicked. The game lasts for 45 minutes and the winner is obviously the team which has achieved the most goals.
The play can be followed on a Google Maps mashup which allows viewers to monitor a scoreboard and see the locations of each of the 22 players as they make their way around the course, which is the streets of Amsterdam.
Here is a promotional video of the game being played in Amsterdam.
Navball is the brainchild of The Saints mobile software, one of many innovative Dutch developers. Another application they have launched which would be great fun for both tourists and locals is Get Lost in Rotterdam. It’s sort of like a treasure hunt, except that it is simply about finding new places and having fun. It is designed such that it could be played in any city in the world.
You send a free txt message to a short code and can then download the application which has 15 consecutive instructions. I watched a video demonstration on the website, which went like this:
1. Get on the tram heading for the city centre and get off at the 5th stop.
2. Take the first Metro (subway) entrance and go one stop.
3. Follow the first dog you see for (x) time and then turn left
4. Catch the first available bus. etc
There are lots of prizes for people who send in photos from their journey and the game will run on many different brands and models of phone that have Java capability.
These games are entertaining, fun, involve adventure and exercise. I don’t know if they allow you to track the people or their trail on a map website like AA Maps, but that would obviously add some more fu, not only to the players but to others.
So there are a couple of cool examples of LBS Games. What do you think you could come up with? You can enter to win prizes with your idea at www.locationinnovation.co.nz. If it’s really good, you could be heading for a free trip to the USA to the Where 2.0 conference in May next year!
