Environmental pollution and natural degradation of materials cause deterioration in buildings, initiating pathological processes that require conservation actions. Architectural Photogrammetry will be discussed as a tool to identify different pathologies on buildings and to accurately measure deflections. A photographic study was conducted of the most common deflections on reinforced concrete structures, with samples of different ages and locations exposed to various environments within Holguin Province in Cuba to detect deterioration characteristics, causes and possible treatments. A comparative analysis of other common methods and instruments currently used to measure structural pathologies highlights the efficiency of architectural photogrammetry. Photogrammetry is suitable to study the most common pathologies, their causes, and potential solutions. These include: cracks, fissures, deflection in beams, footing settlement, slenderness in columns, and more. In addition to the scope and efficiency of photogrammetry, this technology also facilitates studying inaccessible points on large elements. The instantaneous recording of accurate data about physical objects gives photogrammetry advantages over conventional structural analysis methods.

Preparing for natural disasters is vital for mitigating harm and loss of important cultural sites. In Cuba, this rigorous planning informed by years of experience has focused on the recuperation phase after a disaster or storm. Governmental agencies plan rehabilitation and reconstruction projects in the short, medium, and long term. Accurate models are essential for planning these recovery projects. Photogrammetry represents a novel way to create these models at a potentially city-wide scale. Images taken with conventional cameras are used for object measurement to create digital 3D models of buildings, which will be stored in an architectural database. Important cultural and historic sites were used as initial case studies for the creation of models through photogrammetry. These catalogs will facilitate the maintenance and assessment of these important sites and help to plan future reconstruction plans after a natural disaster. Photogrammetric corrections cause minimal graphic distortion to provide accurate metrics of geometric and decorative information. Examples of these techniques in other Latin American cities will also be discussed.
