Maps Are Not All Equal

There are reasons why smart car navigation companies use GeoSmart data on their devices. The reasons are that often near enough is not good enough. This week we have seen a good example of this, which was followed up in the news media.

On Wednesday the Otago Daily Times published a story with the headline GPS systems send Peninsula tourists off track. It quoted a Senior Constable who said that tourists were being guided onto paper roads and dirt tracks by car navigation systems and certainly into areas not suitable for most vehicles.

An example given was that people were trying to drive all the way to the seal colony shown on the map here, via Cape Saunders Rd. As you can see on our map, that isn’t possible, but there appears to be a paper road on some car nav products (obviously not using GeoSmart Maps) that say you can.

Because we are the premier supplier of quality car navigation map data for New Zealand, the obvious query came to GeoSmart for some clarification on this. We are the market leader in car navigation in New Zealand because of the quality of data. We have quality data because we are local and because we have invested heavily for over 12 years in having quality data for car navigation. We have a map room full of people who are committed to having up to date information on our maps including eliminating paper roads, maintaining speed zones, current information on Points of Interest, turn restrictions such as 1-way streets, no left turns, median barriers and also what we know as implicit turn restrictions, which is where a large vehicle may not be able to safely complete a turn even if it is legal to do so. As a consequence, brands like TomTom and Navman use our information in order to ensure that their valued users do get quality instructions.

I received a call from the journalist who wrote a follow up story for the NZ Herald with the headline Don’t just go where the GPS says – if it looks like a paddock it probably is one. I explained that when we first decided to become a car navigation map provider, partnering with brands such as Navman, Siemens VDO and BMW, we processed the Government data (which was never designed for guidance) and found that it was not suitable for car navigation. There were huge numbers of paper roads (roads that have been drafted but not (yet) constructed and situations where entire settlements were 60-80 or more metres away from where the maps said they were.

We then set out to drive every public road in New Zealand, getting accurate data with the technology of the day, eliminating the paper roads and at the same time getting key information such as speed zones, road class, points of interest including things like rest areas, ATM’s, public toilets as well as business, tourism and travel, hospitality, sport etc. Today we continue to drive, capturing a road centreline at sub 1 meter accuracy as well as information such as the incline of the road for eco-routing and the angle of the camber on corners for future truck safety systems and of course real time traffic which can be found online at AA Maps, AA Roadwatch and AA Journey Times and is of course used by TomTom and Navman.

A key issue that we have identified in recent times is that a lot of car navigation users don’t realise that they need to update their maps regularly. In New Zealand roads are changing continually. They are road realignments, new motorways, new subdivisions, suburbs and settlements being built all the time. Roundabouts get replaced with traffic lights and traffic lights get replaced with roundabouts and it never ends. GeoSmart does a new update each and every quarter, 4 times a year and they are all significant updates. Just because you have a navigation unit that is only 6 months old, doesn’t mean that it has the latest data. Even if you have just bought a unit brand new, it is worth plugging it in to your computer to see if there is a new map available.

The acid test is www.aamaps.co.nz. This also gets updated every 3 months. If a road or segment is on AA Maps, then it is in our data and will either be in the latest car nav map for the brands that use our data, or is about to be. If it isn’t on AA Maps, then we are probably adding it, but we would love to hear from you just in case. All you need to do is click on the feedback button on the AA Maps web page, select the type of feedback you want to give us and the information will go to the appropriate team member. We are Kiwis, we live here and we take pride in the quality of our data and want you to enjoy your motoring.
