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’.

What Tools Do You Need To Create An LBS Application in New Zealand Part One

The first thing you need is a map. Many people seem to think (as I did before I joined GeoSmart) that maps are fundamentally the same and equal. Makes sense doesn’t it. We’re a small country and you would expect all maps to have the same data.

That would seem to make sense given that the core data for New Zealand is supplied by the Government under the Land Institute of New Zealand. LINZ is the authority when it comes to things cadastral. They manage land titles, topographic data about New Zealand, hydrographic information, the official street name register and is a part of the NZ Geographic Board which is currently busy deciding whether Wanganui should now be called Whanganui.

When GeoSmart decided to enter the car navigation business, we quckly found that the ‘official’ maps of New Zealand have a ‘computed road centreline’. In effect that means that they use a system which places the road notionally between property boundaries. This wasn’t a big deal when it came to road maps because a road map requires that you plan your rate based on a paper image and if it is not exactly right, you can interpret the map and get to your desired location. This data also contains ‘paper roads’. Paper roads are unformed roads that were draughted in Scotland in the late 1800’s and never constructed. Again if you were to see a road on a map and it physically isn’t there, no problem, you can work your way around it. Consumers Institute has a number of pages on this topic.

Whilst not an issue on a printed map, consider the problems if you tried to use this data for car navigation and routing. When GeoSmart made the commitment to develop a car navigation database, it was quickly realised that it was necessary to drive every road in New Zealand and also use information gleaned from its Orthophotography in order to create an accurate road centreline database. In doing so, we were also able to capture information including one way streets, dual carriageways, turn restrictions, speed zones, the actual name on the street signs (which were sometimes different to the LINZ data) whether a road was paved or not and much more. In doing this we were able to create a database suitable for car navigation (over 90% market share including TomTom and Navman)  and many other services including Fleet Management (around 80% market share including Navman Wireless, Astrata, Xlerate, Argus Tracking, Blackhawk).

Fleet management is even more critical. One of the key reasons companies buy Fleet Management solutions is because they can claim back Road User Charges (RUC) as they are not liable to pay taxes when their trucks are on private property. If they were to try to do this using the computed road centreline, they would struggle to pass a Tax Audit because using in accurate maps, they could often be calculated to be off-road, when they are actually on the road. You can best see this in evidence by using a map dataset which overlays aerial or satellite imagery with the cadastral map data set. Especially in rural areas you will find that there are major discrepancies between the photography and the map data.

So after that long journey, GeoSmart is now able to offer you access to the Web Mapping API, which can enable you to offer routing, driving directions and other tools including displaying map tiles on a mobile or PDA display. You can search for streets, numbers and businesses.

If you explore the many LBS applications being developed overseas (some of which this blog will cover in the near future, you will see that driving or turn by turn directions are a very popular feature of LBS applications. Whether it is a LBS game, a buddy finder, proximity based marketing, planning a run or cycle trip, routing has a part to play and is one of the major reasons that people internationally use LBS applications. If you don’t have a map book (we create the Wises and AA Maps you probably have in your car)  or folded map with you, you have less opportunity to interpret data that is inaccurate, so it is imperative that you use accurate information in your application.In countries where the Government provides accurate maps (such as the USA) this is very easy to do, but in New Zealand, to date only GeoSmart has a fully driven road centreline. And of course as you know from a previous blog, we are now re driving all of New Zealand in the RAPIDcV with around 20cm accuracy.

So if you want to create an application with accurate maps and directions, the SmartFind WebMap API is a key component. If you would like to check this out, we do of course have the ability to give you a Developer Agreement at no cost so that you can start creating your application.
