Summary
This document discusses the integration of computer-aided design/building information modeling (CAD/BIM) and geographic information systems (GIS) for building modeling. It examines the challenges and benefits of such integration, detailing how buildings can be modeled within a broader urban environment. The document also discusses data interoperability issues and the potential for enhanced analytical capabilities.

AS.430.607.81 -‐ Geodatabase Architecture Geo-Database Architecture: Module 10 CAD/BIM and GIS How to “put” buildings & utilities on the map! Integration Part 10-I 1 AS.430.607.81 -‐ Geodatabase Architecture Introduction CAD/BIM & GIS Integration WHY? WHAT IS THE CHALLENGE? ? HOW IT CAN HELP ME? WHAT IS THE STATUS QUO IN THE INDUSTRY? 2 AS.430.607.81 -‐ Geodatabase Architecture GIS & Buildings vs. CAD & Buildings 1860 1880 http://www.bostonfirehistory.org/gonefirehouseengine04a.html http://en.wikipedia.org/wiki/File:Boston_ground_1880.jpg 3 AS.430.607.81 -‐ Geodatabase Architecture GIS & Buildings vs. CAD & Buildings BUILDINGS are “BLACK BOXES”! “OBSTACLES” :: “ORIGIN/DESTINATIONS”!

(GIS used to be “foot” level accuracy only) 8 AS.430.607.81 -‐ Geodatabase Architecture GIS & Buildings vs. CAD & Buildings GIS are not just ‘maps’! GIS are not just ‘2D’! Bring Buildings in 3D! Analysis of assets! Spatial Relationships within the building! Spatial Relationships of assets among several buildings! ! 2005 ? When a group/ department is defragmented? 9 AS.430.607.81 -‐ Geodatabase Architecture Buildings are complex systems ESRI CityEngine http://www.smarterbettercities.ch/3dgis-hospital/ 10 AS.430.607.81 -‐ Geodatabase Architecture Buildings have a Lifetime CYCLE Data InterOp issues B$15 annually http://www.smarterbettercities.ch/3dgis-hospital/ 11 AS.430.607.81 -‐ Geodatabase Architecture Buildings have a Lifetime CYCLE GIS http://www.smarterbettercities.ch/3dgis-hospital/ GIS becomes a part of Facilities Management domain 12 AS.430.607.81 -‐ Geodatabase Architecture Traditional approach models buildings individually IS any building ISOLATED from its ENV?

THIS CALLS FOR AN INTEGRAL APPROACH TO INTEGRATE BUILDINGS INTO GIS DOMAIN! ! AS IT WILL PROVIDE UNIQUE ANALYTICAL ABILITIES TO DECISION MAKERS http://www.192021.org 22 AS.430.607.81 -‐ Geodatabase Architecture Principles of such integration (CAD&GIS) … given the fact that majority of the existing buildings data are in CAD/BIM ! systems/formats. 23 AS.430.607.81 -‐ Geodatabase Architecture Principles of such integration (CAD&GIS) … given the fact that majority of the existing buildings data are in CAD/BIM ! systems/formats. 24 AS.430.607.81 -‐ Geodatabase Architecture The Action Plan: ! Explore CAD -> GIS Integration Workflows! ! Explore CAD Utilities -> GIS Workflows! ! Explore CAD drawings’ georeferencing! 25
