The authors use the method of analysis and synthesis, called "Urban Indaganda" (IU), to inventory, recognize and valorize the resources of urbanized space. This proprietary research and teaching method involves characterizing and evaluating the basic elements of urban development. Urban Indaganda encompasses selected urban spaces on a scale of region – city – district – city block – plot – house – detail. The inspiration for developing the method was the "royal geographical event of Stanisław August Poniatowski - Urban planning indaganda of cities and regions" and the plans of the Commission of Good Order (Commissio Boni Ordinis, from 1765) of Stanisław August Poniatowski. The article describes the IU research method and the Indaganda Tables. Based on the obtained results, various albums of elements characteristic of a given space and catalogs of forms used or approved for use in new development projects can be developed. The inventory of resources is valuable. An additional element of valuation will allow for the analysis of research results in terms of the necessity and scope of interventions and transformations in the space. The authors presented the implementation of the Indaganda Boards as part of the organization of summer field classes on urban inventory at the Department of Urban Planning WAPP.
