The consortium that currently dominates digital data
for the most part is ESRI redlands CA, authors of ARC
suite of GIS tools that are the current standard. RMSI
India which is the outsourcer and does a lot of
dataprocessing as the industry is increasingly
automated. Tele Atlas and NavTeq as the two largest
competing data providers. check data souces on
mapquest  or any online commercial mapping site.
