I am searching for building/property data which include building height, building area, lot size, and building type classifications(preferably as complete as possible). I am working on an Earthquake Model for highly urbanized locations, especially those around fault lines.

  • If asked today, or if in need of any follow up, I think the Open Data Stack Exchange would be the place to ask this.

Maybe a possible approach few cities have 3d models for many of their buildings in google earth. Perhaps you can check whether these can be downloaded and used in another tool?


CityGML is an approach to provide such a data in a more standardized way, but I don't think they have much data available. http://www.citygmlwiki.org/index.php/Main_Page


Here is one approach to try and find building heights.

  1. The idea is to download the open street map building footprints dataset. Got mine from here: http://download.geofabrik.de/

  2. Download lidar data from here: http://earthexplorer.usgs.gov/

  3. Do a spatial join with the lidar points on the building boundaries

  4. Find the max height of the points for each building.


The only thing that even comes close AFAIK is the national cadastre.


This organization might have part of it. You will likely have to assemble it yourself. National Cadastre dot org

  • Your link only covers the data model. Do you have a link to data? Commented Dec 17, 2010 at 2:58

There was a previous question (Finding footprint data for US buildings?) just regarding building data. In the USA, Massachusetts has both building data and lot outlines (I'm not sure about building type classifications).

I would also explore OpenStreetMap as perhaps this data exists for some countries.
