    33. 33. Merged Model – Geometry and Info in same tables</li></ul>Model Used: the Merged BISDM Model<br /><ul><li> Easier to work with in ArcGIS, enables using some convenient built-in capabilities of ArcGIS</li></li></ul><li>BISDM Data Model for Smithsonian<br />Entities Modeled:<br /><ul><li> Property
    34. 34. Building
    35. 35. Floor
    36. 36. Room
    37. 37. Equipment
    38. 38. Property Extents
    39. 39. Building Footprints
    40. 40. Boundary Lines</li></ul>Relationships: (hierarchy)<br /><ul><li>Properties have buildings
    41. 41. Buildings have floors
    42. 42. Floors have rooms
    43. 43. Rooms have equipment</li></li></ul><li>BISDM – Relationship Classes<br />A single “identify” query on the map in ArcMap provides access to a large assortment of related information automatically<br />
    44. 44. Advantages of GIS<br />Quick, Easy Answers to Questions:<br />How many conference spaces are there in Panama?<br />Answer: 13<br />How much square footage of conference space is there in Panama?<br />Answer: 532.5 sqm= 5,731 sqft<br />Both questions can be answered with the same selection query<br />
    45. 45. Advantages of GIS<br />Example More Complex Question:<br />How many private office and shared office spaces are there on floor 3 of building 2 at the Tupper Complex?<br />Answer: 10 spaces<br />What is the square footage of those spaces?<br />Answer: 180 sqm = 1937.5 sqft<br />More complex query but almost the same amount of time and effort to create as a simple one – minimal effort.<br />
    46. 46. GIS Tools for BISDM Data<br />Working in GIS with Data in BISDM:<br /><ul><li> Multi-floor data is spatially coincident (X,Y)
    47. 47. Editing floorplan linear features requires many steps
    48. 48. Can be difficult to add new data (no good alignment tools)</li></ul>BISDM Extension for ArcMap<br />Contains tools for:<br /><ul><li> Isolating floor of interest
    49. 49. Editing data
    50. 50. Guideline tools for creating data
    51. 51. Raster clip (environmental rasters)</li></li></ul><li>GIS Tools for BISDM Data<br />Example tool: Floor Picker<br />All floor data displayed simultaneously:<br />Visually cluttered!<br />Floor Picker used:<br />Only the floor of interest shown<br />
    52. 52. Web Application <br /><ul><li> Customized version of the Penobscot Bay Media Web Visualization software (now called InVision Portal)
    53. 53. Data in ArcSDE Database, accessed through ArcGIS Server

    60. 60. Published as a Globe Service on ArcGIS Server
    61. 61. Consumed using ArcGIS Explorer E2</li></li></ul><li>3D Web Service<br /><ul><li> Data is easily accessed using a free viewer similar to Google Earth
    62. 62. Allows qualitative data analysis and exploration of data</li></li></ul><li>Lessons Learned<br /><ul><li> Our current data set is quite robust – can answer most facilities questions quickly if we use the right software.
    63. 63. Data editing at SI can be dramatically improved if we use the right software/database.
    64. 64. ESRI / AutoDesk software are not currently interoperable for BIM use
    65. 65. Autodesk Revit – great design tool
    66. 66. ESRI Spatial Analyst – great analytical tool</li></li></ul><li>36<br />The Future of <br />BIM at SI<br />
    67. 67. Near Term Goals<br /><ul><li>Continue piloting BIM using our tools of choice:
    68. 68. AutoDesk Revit
    69. 69. Adobe Flex API
    70. 70. ESRI ArcGIS Server
    71. 71. Determine the best fit/best value of BIM in our organization: </li></ul>Requirements for a BIM design project are extremely complex when compared with BIM requirements for operations – where will SI’s money and effort be better spent? <br />
