Description

The data consists of the attributes affecting seismic performance of a sample of 7,294 buildings from the San José canton in Costa Rica, Central America. Contains information about the occupancy type, number of floors, material and type of lateral load resisting system, structural regularity, floor and roof properties (following the GEM Building Taxonomy v2.0). The attributes were identified from panoramic images of the buildings when applying remote surveys by a team of trained last-year civil engineering students supervised by civil engineers from the Seismic Engineering Laboratory of the Engineering Research Institute from the University of Costa Rica (LIS-INII-UCR). The visual data were collected on October 2017 by means of the GFZ Mobile Mapping System and the remote surveys were completed on July 2019 by means of the GFZ Remote Rapid Visual Screening platform. The sample buildings were selected by a random stratified sampling with proportional allocation applied to the building population. Additional information of interest from the sample buildings, not obtained from the panoramic images, is provided. It consists of the location (coordinates), footprint area, approximate construction period of each building and its corresponding district and neighborhood (hierarchy of geographical administrative units of Costa Rica is as follows: province, canton, district and neighborhood). The approximate construction period was determined by manually analyzing aerial photographs of San José for different time periods. The main file is "sampleDB.csv", which contains all the information represented by alphabetical and alphanumerical codes that are explained and described in the files "attribute_type_descriptions.csv" and "attribute_value_descriptions.csv". The attribute types can take different attribute values, for example, for attribute type "llrs" (lateral load resisting system as described in attribute_type_descriptions file), some posible values are LWAL and LDUA (wall and dual type, respectively, as described on attribute_values_descriptions file). This data can be use to generate a high resolution building inventory to take part of an exposure model for performing seismic or multi-hazard risk assessments. It can also be used for other studies that need a general but high level description of the buildings from San José canton. The data was obtained as part of a seismic risk assessment conducted by LIS-INII-UCR , with funding from the Costa Rica Republic “Transitory 1 of the National Emergencies Law (N° 8488)” assigned to this laboratory.
