Nokia heats up its maps

Published by at

Nokia has added a new feature to its Maps web service - heat mapping. While you may be forgiven for assuming this is for meteorological purposes, it's actually to help you find your way around! Apparently, the points of interest (POI) density in Nokia's geographic database is so high that it has become unwieldy to show everything in a given category below a certain zoom level.

To that end, the Nokia Maps web team have introduced heat maps to indicate the relative density of POIs across a given area. This functionality isn't yet in the mobile clients for Symbian and Windows Phone 7, but we wouldn't be surprised if Nokia added it in the future.  

You can try Nokia's heat maps out for yourself by visiting, then drag to an area you're planning to visit and select a category from the 'Features' drop down list in the top-right corner.
