For over a year now, since arriving in Southampton to study Computer Science at the University, I have been also working on improving OpenStreetMap. I forget how it I found out about the project, but initialy, I set about mapping in detail my hall of residence at Wessex Lane.
After that, I moved on to improving Highfield Campus, if I remember correctly, the first thing I did was to add all the missing buildings. I also began mapping in detail the residential areas that I frequently walked through when traveling to and from campus.
I also set about adding all the missing building outlines to the city centre, and surrounding areas. Currently, a large part of the middle of Southampton is mapped in some detail. Most of the buildings are present, and some of the buildings have the address information. A good way to look at this is using the ITO World map
Over the summer, I hope to add address information to the most of the buildings that I have added, that are currently missing it. Hopeully I will be able to join up the areas that I am mapping in the centre, with the excellent work going on to the west in Shirley
