Lewisham Council has launched a new website for people to share information about their area to help improve the environment.
Love Clean Streets is a free online tool which allows people who work or live in London to upload photographs of the area around them.
Photographs can be of a neighbourhood's “loved” qualities which the user would like to share with others to promote the area.
It can also be something “unloved” which the user would like to bring to the attention of their local authority such as graffiti or flytipping.
Once the photos are uploaded they are displayed on high-tech maps which can be viewed by anyone.
People can also see how local authorities are responding to “unloved” areas.
Users can submit reports using the free iPhone or Windows Mobile application by sending a text or by visiting the web site.
They can search for all the reports in their area, share them via social networking sites, review progress, or subscribe to updates.
Mayor of Lewisham Sir Steve Bullock, said: “This is an excellent new development.
“Improving the physical environment of a neighbourhood makes an enormous difference to the quality of life for those living in it.
“Thanks to a lot of hard work and some amazing technological advances Lewisham's new scheme will make a real difference to the lives of Londoners.”
Lewisham Council has run its own online scheme for the past five years called Love Lewisham.
Since the project started the number of enviro-crimes in the borough has fallen.
According to the Audit Commssion complaints about graffiti have fallen by 30 per cent and between June 2007 and August 2009 the amount of graffiti observed in the borough fell by 8 per cent.
