According to the Navteq press release: “The major highways, secondary roads, and arterial streets in these cities have been verified against 615+ validation rules and conform to Navteq's standard global data specification. This attention to detail provides customers with a high quality dataset and allows them to use the data immediately with other Navteq maps.” Additionally, the Navteq map of Turkey contains connector roads throughout the country, connecting the country's largest cities to each other and linking Turkey to Bulgaria and Greece.
The Turkish navigation market has been growing despite the lack of map data from the biggest international providers TeleAtlas and Navteq. AND Automotive Navigation Data, a Netherland based map provider, announced in April this year to have signed ALK as a customer for its Turkish map data. The AND press release mentions the following coverage: “16 cities on full street level, all cities and villages connected to the road network, and a total of more than 355,000 kilometres of roads”.
Navturk, a local company, has also been selling navigation solutions in Turkey since September 2005, having developed its own software and map data, currently running on a Mio PND and a HP Smartphone. The NavTurk map data offers street details of 35 cities, 40,000 residential areas, 70,000 kilometers of highway and more than 100,000 Points of Interest.
