Since the approval of the Brazilian Federal Technical Assistance Law, whose objective is to guarantee adequate technical assistance to the residents of poor areas to improve their homes, several municipalities have implemented programs, not always successful, to improve housing in slums. Aiming to subsidize these programs implementation workflow, the present paper analyses use of drones as a tool to gather information about the physical characteristics slum households in Salvador de Bahia city, Brazil. As an experiment we flight over a single census sector within the Alto das Pombas slum, and after image processing we extracted and organized the collected data, extracting the possible information that could be applied to identify and quantify the most precarious houses that could be prioritized from a health improvement perspective. We conclude that many of the necessary data needed, on the urbanistic scale in Brazilian slums, can benefit from drone photogrammetry at low cost and fast execution.

The paper deals with the issue of affordable housing provision for low income populations in the developing countries and its significance in the European context. My goal is to discuss this topic through the analysis of different approaches to household provision and improvement with special focus on the involvement of communities in various upgrading procedures. Separate sections of the paper refer to the most important approaches developed in the 20th and 21st centuries. These include: site and service, slum upgrading, incremental housing and communityled upgrading which are analysed through the prism of several examples coming from various parts of the world. The discussion of the strategies formulated in the developing world is linked with the new approaches towards housing provision that are presently promoted or are spontaneously emerging in various cities of Central Europe. These include the issues of container-houses construction in Poland and the creation of informal settlements by Roma populations in Polish and Slovakian cities.
