Gordon Brown will promise a hi-tech revolution in Britain's public services today.

The Prime Minister is to highlight the crucial role of technology in cutting crime and giving people real power over education and healthcare.

He will also stress its importance in raising awareness of climate change - launching an interactive mapping website so the public can see the threat.

Speaking to an audience of executives at a conference organised by internet giant Google, Mr Brown will say: "My aim is to ensure we utilise all the innovation at our disposal to improve public services in this country and to give more power to those who use them."

He is to praise government "successes" such as introducing broadband into every school, electronic border controls and electronic data records in hospitals.

There will also be pledges to push ahead with neighbourhood "crime mapping", video identification of suspects, electronic school report cards, and online GP appointment booking.

"Across government and the public services we must present and distribute the information we hold in a way that enables it to be reused by online communities, potentially reaching many millions more people and helping make Britain a country of technology pioneers," Mr Brown will say.

"I will do all we can to ensure we remain the investment and cultural destination of choice for the creative industries and the technological businesses of the world."

The annual Zeitgeist event will be given a demonstration of the new online mapping system, which uses the popular Google Earth technology together with climate modelling information from the Government, Met Office, Hadley Centre and British Antarctic Survey.

Mr Brown will describe it as "a new mapping of the world that tells us what is happening now to our land, our seas and our people - and that projects into the future what will happen to the planet we share if climate change is left unchecked - providing a powerful stimulus to public awareness and action, generating new ideas and new solutions".
