Tele Atlas started the development of this new database three years ago said Global Product Director Purvi Rajani. This new database is addressing three major issues faced by map data users: time to market, map size and single worldwide specification.
First, Tele Atlas has optimized its data structure to enable developers to compile data faster. “We have built our data in a way that is much closer to the final runtime environment of our customers”, said Purvi Rajani. Additionally, “we have built in indexes, which allow developers to compile countries without having to deal with local specificities such as ZIP codes or States”.
Second, Tele Atlas has reduced its data foot print to optimize cost, especially for mobile devices. “In addition to the full geometric network and display layers, a reduced shapepoint layer is included with accuracy within one meter of the detailed layer. The generalized layer preserves geometry without compromising
accuracy of routing, geocoding, or display functionality”, explains Tele Atlas.
Mobile navigation software developer Sygic, who was part of a pilot of this database reported reduction of approximately 30-40 percent in the overall data footprint on devices. Tele Atlas digital map data for all available European countries can now fit on SD cards with less than 2 gigabytes of memory with full functionality and quality included.
Third, multiNav has now a single worldwide format which spans “across 27.2 million kilometers in more than 70 countries, to the front doors of 1.9 billion people”.
