one great video by the secretaria municipal de habitação do rio de janeiro -  smh (municipal housing department of rio de janeiro) can be seen here, and shows chapéu mangueira from the air and planned projects for the morar carioca program.        

smh is the same office in charge of the 'minha casa minha vida' (my home my life) program, aimed the construction of better housing for residents in need.   

an aerial view of chapéu mangueira can be seen on this wikimapia, also clearly mapping the surrounding areas and nearby communities.   if 'far away' map opens, do not scroll, just zoom.
