The structure layer was developed by the Coeur d'Alene Tribe's GIS office and is a depiction of all structure types (i.e. houses, barns, shops, schools, etc.). The points are locations of existing structures found throughout the Tribe's reservation as well as all buildings in Benewah County, Idaho. Most of the data gathered for each building was done for the purpose of informing fire fighters of the access, safety hazards, and firefighting opportunities at each location. This data includes buildings material, roofing class, water source, response distance, number of access roads, road width, fire truck access, vegetation densities, topography around the building, defensible space, slope characteristics, burn barrel status, and fuel tank type. The remaining data is pertinent to the building's physical description like, the address, the building type, occupancy status, commercial status, house number, comments, and coordinates. In addition, images of most strucutres are recorded in the database.
Most of the data collected and/or derived for each structure follows protocols set forth by the National Fire Protection Agency (NFPA) Form 1144 with certain modifications. The entity and attribute section of this document details the source of each attribute and when or if it was modified from the NFPA standard.
