LARIAC4 BUILDINGS DELETED 2017

** Download as File GeodatabaseThe Countywide building outline dataset contains building outlines (over 3,000,000) for all buildings in Los Angeles County, including building height, and building area (also known as building footprints). This data was captured from stereo imagery as part of the LARIAC2 Project (2008 acquisition) and was updated as part of the LARIAC4 (2014) & LARIAC5 (2017) imagery acquisition.Most of the buildings in this dataset were generated using stereo imagery. This means that the person capturing the buildings actually saw them in 3-D, and therefore was able to more accurately capture the location of the roof line, since this method eliminated the impacts of building lean (where the height of the building impacts its apparent location). Basically this is the most accurate method for capturing building outlines. In many cases the location is more accurate than our aerial photography and parcel boundaries.This file contains a file geodatabase which has two feature classes:LARIAC5_BUILDINGS_2017 – this is the current set of buildings as of 2017LARIAC4_BUILDINGS_DELETED_2017 – these are the buildings from LARIAC4 that have been modified or deleted. These can be for change analysis and detection.
