Debate Continues: BIM versus GIS

I recently had the pleasure of participating in a panel discussion entitled, “The Great BIM versus GIS Debate”. This 90-minute session in front of a packed room was moderated by Matt Ball (@SpatialSustain) and proved to be a lively (and sometimes heated) discussion between myself (@engis), Pete Southwood (@Geo_Pete) and members of the audience. Issues addressed in the debate encompassed technology; data accuracy, access, integration and analysis; collaboration and efficiency; and the future of GIS and BIM.

I introduced this debate during a previous blog post which you can find here. However, if you were unable to attend or simply want to review some of the highlights, I encourage you to check-out the following:

Dale Lutz (@DaleAtSafe) posted his thoughts on the debate here. Although there was no clear knock-out punch by either opponent, he did include a list of the best (and some would say hilarious) “zingers”.

Matt Ball (@SpatialSustain) posted his thoughtful perspectives of the debate here. His great summary covers “Concepts or Tools”, “Point of Truth” and “Integrated Infrastructure Information”.

I’ve also posted a replay of “The Great BIM versus GIS Debate” to YouTube. For those of you wanting to review the debate in its entirety, I’ve made a recording of the complete 90-minute session which I divided into chapters which you can access via the links below:

The Great BIM versus GIS Debate

Are you a GIS professional convinced that GIS is the technology of choice for mapping and analyzing the world we live in?

Are you an engineer or architect with years of CAD experience confident in your abilities to create cost effective and sustainable designs?

Regardless of which camp (GIS or CAD) that you may be a part of, “The Great BIM versus GIS Debate” is sure to be a lively session at Autodesk University this year.

GIS gives us a way of mapping, analyzing and managing our real world assets within a geospatial context. It gives us a way of integrating and relating seemingly disparate data sets based on geography. GIS is a tremendously useful planning tool that helps provide us with insight into our infrastructure projects in a way that traditional CAD technology cannot.

BIM is similar to GIS in some ways. If you are unfamiliar with BIM as it applies to infrastructure then I encourage you to check out a detailed explanation in my previous blog post. Simply put, BIM is Information Modeling for the Built environment. It’s is a process - not software - a process that lets you explore the physical and functional characteristics of your project digitally, before it’s built. At the heart of BIM is an information model – a model that is used throughout the infrastructure lifecycle – a model that is passed from planning and conceptual design phases to detailed design, construction and then to management phases. As a result, the application of the BIM process can lead to significant time and dollar savings during construction and additional savings throughout the life of the asset as a result of better more sustainable designs.

So, when it comes to supporting the infrastructure lifecycle, which is better? BIM or GIS. Both BIM and GIS have their advantages; both have their supporters.

Well, if you’re unsure about BIM as it applies to GIS or visa-versa, then I encourage you to check out the “The Great BIM versus GIS Debate” at Autodesk University. This panel session will be moderated by Matt Ball (@SpatialSustain). Peter Southwood (@Geo_Pete) and I (@engis) will be opposing each other on behalf of the two camps: GIS and BIM. With what I am sure will be provocative questions from Matt Ball and audience members, Peter and I will feel the heat as we do our best to respond to questions encompassing technology; data accuracy, access, integration and analysis; collaboration and efficiency; and the future of GIS and BIM.

Better Infrastructure Planning with AutoCAD Map 3D – AU Virtual

If you are unable to travel to Las Vegas to attend Autodesk University in person this year, you can still participate virtually by registering for AU Virtual. It’s free and only takes a moment to register.

And while on-line with AU Virtual, why not make a point of catching my virtual session, entitled “Better Infrastructure Planning with AutoCAD Map 3D”. Attend this session to see how you can turn today's planning and design challenges to your advantage with Building Information Modeling (BIM) and a more powerful and productive AutoCAD Map 3D.

BIM for infrastructure is creating a cultural shift in infrastructure planning and design workflows. Increasingly, infrastructure planning and geospatial professionals working on transportation, utility, and other infrastructure projects are being asked to integrate planning data with BIM models to more directly represent as-builts and better leverage "GIS ready" design data. Attend this virtual session and discover how AutoCAD Map 3D can help.

AU Virtual, Class GS5581. Tune in on November 29, 2011.

Model Your World

Last year, in honor of GIS Day, my colleagues and I created a webcast that highlighted Building Information Modeling (BIM) and its impact on the geospatial community. I also blogged about this topic a short time later via GIS User.

This year, for GIS Day 2011 and consistent with the BIM and GIS themes, I created an on-demand webcast that highlights Autodesk Infrastructure Modeler – a new geospatially enabled, 3D conceptual design tool from Autodesk.

With Autodesk Infrastructure Modeler, explore “what could be” in the context of “what is” whether you’re:

• An architect interested in site development and the placement, orientation and shape of a new building
• A municipal planner examining the impact of new land use and zoning policies on the city skyline and local neighborhoods
• A transportation planner or civil engineer exploring options for a new highway corridor
• A campus authority looking for more compelling, non-technical ways to communicate proposed re-development ideas to project stakeholders
• Someone involved in conceptual design, 3D GIS, or BIM

View this webcast to see how you can incorporate existing 2D CAD, GIS, BIM, and raster data to quickly create 3D models that more realistically depict the local environment.

Learn how you can easily evaluate multiple design alternatives in the context of the existing environment by overlaying GIS data and using infrastructure sketching and proposal management tools.

See how you can communicate visually rich proposals of these alternatives with interactive navigations, rendered images, and recorded videos.

Follow this link to access the on-demand webcast and learn more about how you can explore “what could be” in the context of “what is” with this new software from Autodesk: http://www.autodesk.com/modelyourworld

What is BIM?

With over 150 sessions either highlighting or referencing BIM at Autodesk University (AU2010), BIM was certainly a popular topic. And now, you probably know that BIM is about using model based designs for better planning, faster visualization and stronger management. But if you’re looking for a brief explanation of what BIM is so that you can share what you’ve learned with your colleagues in a way that doesn’t cause their eyes to glaze over, check out the these two short videos.

This first video explores an entire project lifecycle and shows how BIM solutions can help make our cities more sustainable.

This second video emphasizes the role of information modeling in planning, designing, visualizing and managing municipal and utility infrastructure.

CAD/GIS Integration Problems Persist

Whether it’s CAD or GIS, we all use a variety of tools to get the job done. One would think though that after more than 20 years, the task of integrating CAD and GIS data would no longer be a problem.

Imagine my surprise then when both of my Unconference Sessions at Autodesk University (AU2010) were filled to capacity.

Each session began by exposing the magnitude of the CAD/GIS integration problem – a billion dollar problem that impacts engineers, contractors and suppliers throughout the planning, design and construction phases. However, these impacts pale in comparison to the many billions lost due to a lack of interoperability by the owner/operators during operation and maintenance phases (NIST).

Participants were then divided into small groups to discuss their own CAD/GIS integration problems. The results were interesting. Technology it seems was not the main point of discussion. In fact, organizational influences, data ownership, lack of understanding, workflow and standards were the primary factors contributing to an organization’s lack of data integration.



Next, participants were asked to come up with a list of possible solutions. Again, rather than “fix the technology”, discussions centered around solving data related issues and increasing communication, collaboration and education on the CAD/GIS integration topic.



The session concluded by participants sharing their plan-of-action for tackling the issues exposed. In fact, when I asked participants, "Who is committed to tackling the CAD/GIS integration problem within their own organizations?", the vast majority raised their hands in a resounding yes!

If you were one of my session participants or are in the process of tackling your own CAD/GIS integration issues, please share your experiences by sending me a note or including a comment. I would love to hear about your progress.

For more session highlights, please check out Spatial Sustain and Matt Ball's blog on this topic.

CAD/GIS Integration and Autodesk LandXplorer at AU2010

Are you struggling with CAD/GIS data integration? Well, if enrollments for my two AU2010 workshops (see blog) on this topic are any indication, it seems that you’re not alone. Data integration is a hot topic!

In fact, when you throw BIM and large-scale city and infrastructure models into the mix, the data integration issues can become overwhelming – especially if you don’t have the right plan or the right tools.

• How do you get the big picture when you need to aggregate CAD and GIS data, wireframes and building models, surfaces and aerial photos?
• How do you analyze and visualize this data in 3D quickly and efficiently?

If these questions resonate with you then check out Autodesk LandXplorer. I’ve blogged about Autodesk LandXplorer previously. But why not register for an Autodesk LandXplorer class while at Autodesk University?

For example, Dan Campbell of the City of Vancouver is delivering a session (CV220-3P) entitled “Claiming New Territory with Autodesk LandXplorer”. I’ve seen Dan Campbell present numerous times. His sessions are always informative, entertaining and filled with lots of eye-candy.

You also don’t want to miss the hands-on lab (CV234-27) being led by Lynda Sharkey of Autodesk. Her lab is an introduction to Autodesk LandXplorer. Oh and be sure to check out the hilarious promo video for her class.

CAD and GIS Integration Workshop at AU2010

If CAD and GIS data integration issues continue to plague your organization, if you’re frustrated by working with unstructured CAD files, if you’re perplexed by rigid GIS data models, if you’re looking for easy ways to add CAD data to your GIS databases, or if you're bewildered by the many obstacles to CAD/GIS integration then my CAD and GIS integration workshop may be for you.

This year, at Autodesk University (AU2010), I am delighted to be facilitating two Unconference Sessions entitled, “The Billion Dollar Opportunity: A Workshop on CAD/GIS Integration”. These workshops are aimed at engineers, surveyors, architects, CAD and GIS professionals, and anyone interested in the CAD/GIS integration issue. Anticipated discussion topics will include:

• Drivers for CAD/GIS integration
• CAD/GIS integration scenarios
• Approaches for addressing CAD/GIS integration issues

Note that these workshops fill quickly (the first one is already full). So, if you missed the opportunity to register for my first session (Class ID: CV319-3U), try registering for my repeat session (Class ID: CV220-7U).

But don’t wait; I fully expect the second session to fill too.

See you at AU!

A Cultural Shift in the GIS Industry

In honor of GIS Day 2010, my colleagues Neal Niemiec, Pete Southwood and I have created an on-demand webcast that highlights Building Information Modeling (BIM) and its impact on the geospatial community.

If you’ve never heard of BIM, you’re not alone. Until recently, BIM has been the domain of architects and building owners. However, the application of BIM has expanded. BIM is now being embraced by municipalities, utilities, transportation departments, campuses and others with an interest in infrastructure; it’s not just about buildings anymore.

A Cultural Shift

BIM is creating a cultural shift in the GIS industry. Geospatial professionals know the power of GIS but many have little knowledge or experience with BIM. Increasingly, geospatial professionals are being asked to integrate BIM models with their GIS data. The task is often a struggle as they attempt to combine the data without losing valuable information. As a result, workflow suffers which compromises efficiency, affects decision making, and impacts data accuracy and currency.

An improved understanding of BIM can help overcome these challenges and ensure that BIM models and geospatial data are integrated in a manner that respects both design and GIS requirements.

If CAD and GIS are the Tools, BIM is the Toolbox

BIM is an integrated process that lets you explore a project’s physical and functional characteristics digitally, before it’s built. Again, BIM is not just about buildings; it’s information modeling for the built environment. As such, BIM encompasses CAD and GIS disciplines by combining model-based design with information and analysis.

BIM is multidisciplinary. It combines the complexity of both built and natural environments. It applies to municipal, transportation, utilities, as well as, campus style environments such as education, health care and airport facilities.

Access this on-demand webcast:

• Learn what BIM is and why it’s of importance to the geospatial professional.
• Discover how BIM helps improve CAD/GIS data integration workflows.
• See how intelligent model-based design helps promote “GIS Ready” data.
• Learn how BIM streamlines analysis, visualization and the ability to accurately predict performance, appearance and cost.
• Discover how BIM improves sharing of digital design information, geospatial data, infrastructure models and other documentation among staff and project stakeholders.
• Learn how BIM helps extend your GIS asset information into the design/build process to better coordinate with architects, engineers, contractors and others.
• Learn how to leverage BIM throughout construction, operation and maintenance.
• Discover how BIM helps you deliver projects faster, more economically and with reduced environmental impact.
• Learn how BIM reduces risk through a better understanding of a project’s physical, social and economic impact before breaking ground.

Cadalyst Article on How to Work with Point Clouds

Here's a short post on my latest Cadalyst article. This article focuses on one of my favorite new features in AutoCAD Map 3D 2011: the new point cloud tools for viewing, querying and analyzing 3D laser scanning and LiDAR data sets. I have also posted a video to accompany the article.

Please be sure to check out both the article and the video.

BIM Expanded

This year, I will have had the pleasure of attending several conferences outside of my usual engineering and geospatial interests to include architecture and IT focused events such as:

• MISA Prairies, Spring Conference, April 28 – 30, 2010
• Ontario Association of Architects Conference, May 5-8, 2010
• Royal Architecture Institute of Canada Conference, June 23-28, 2010

What is especially compelling about these events is the opportunity for me to engage participants on the expanded definition of Building Information Modeling (BIM) beyond the traditional architectural focus. One example of this expanded definition for BIM is this article in Green Building Community by Terry Bennett which discusses BIM from a civil engineering perspective.

Another example is BIM for Sustainable Cities which combines model based design from architectural and engineering design perspectives to include the integrated processes that are built on coordinated, consistent information about the municipal developments, infrastructure and related assets.

A BIM for Sustainable Cities plan is part of a 3D digital cities initiative and depends on the convergence of CAD, GIS and BIM and the integration of…

• Modeling and Design
• Surveying & Data Collection
• Planning, Site Selection & Conceptual Design
• Clash Detection, Simulation and Analysis
• Visualization
• Multidiscipline Coordination
• Construction & Construction Management
• Operation and Maintenance

With a BIM for Sustainable Cities plan, municipalities are better able to:

• Coordinate with architects, engineers, contractors and others
• Better share digital design information, geospatial data, infrastructure models and other documentation among staff and project stakeholders
• Use that information to accurately predict performance, appearance and cost
• Reliably deliver municipal projects faster, more economically and with reduced environmental impact
• Leverage model-based design information for operation and maintenance

BIM for Sustainable Cities embraces the entire municipal development lifecycle. This expanded view of BIM gives local governments, planners, engineers, architects, contractors and others an opportunity to take a more active role in neighborhood development and infrastructure projects that are planned, designed, built and managed in greener more sustainable ways.

Cadalyst Article on CAD Queries with AutoCAD Map 3D

Here's a short post on my third Cadalyst article. This article focuses on how to query your AutoCAD drawings with AutoCAD Map 3D. I have also posted a video to accompany the article.

Please be sure to check out both the article and the video.

How to Unlock the Data in your CAD Drawings

Are you using AutoCAD to help plan and manage your infrastructure network? Are you wondering how you can access and better use the information in your AutoCAD drawings? Do you want to be able to analyze your AutoCAD drawings, generate material lists and reports, or reveal new patterns in the data? If so, there is a way with AutoCAD Map 3D – the better AutoCAD for working with your infrastructure data.

With AutoCAD Map 3D you can query your AutoCAD drawings in much the same way that a spreadsheet or database can be queried. For example, with AutoCAD Map 3D, you can query by CAD properties such as color and layer, as well as, by location.

Consider a scenario in which a water utility or municipality is reviewing their watermain replacement program. Cast iron watermains are considered a priority. The AutoCAD drawing containing information about the watermain network must be analyzed to determine the location of the cast iron watermains, as well as, their corresponding lengths and diameters.

To see how this type of analysis can be done, please review the following short video which demonstrates the use of CAD queries in AutoCAD Map 3D.

Dispelling the Myths of CAD/GIS Integration

Psst - it's no secret! CAD and GIS technologies have advanced considerably in the last couple of decades. However, in spite of these advancements, there is still an outdated view of GIS software that is closely integrated with CAD technology. Myths regarding the integration of these two technologies also continue to exist. Unfortunately, the perpetuation of these myths can negatively impact data quality, process efficiency and ultimately an organization’s bottom line.

During the last several months, I tweeted using my Twitter name @engis about the top myths which I feel continue to prevail about today’s CAD in spite of many technological advancements. I have collected these tweets (modified slightly for improved readability) below.

How many of these myths are still prevalent or being perpetuated in your organization?

• Myth: CAD cannot do geospatial topology.
  Reality: Today’s CAD supports both CAD and GIS topologies including node, network and polygon topology and analysis.


• Myth: You can’t query a CAD drawing.
  Reality: Today’s CAD supports geospatial queries including both geographic and attribute based filters.


• Myth: CAD doesn’t do geospatial analysis.
  Reality: Today’s CAD supports topology analysis including overlays, dissolves, buffering, tracing and more.


• Myth: CAD doesn’t do thematic maps.
  Reality: Today’s CAD does support theming. Stylize points, lines, polygons, text without affecting source data.


• Myth: CAD only supports simple points, lines and text.
  Reality: Today’s CAD also supports complex GIS features (eg networks, nested polygons, surfaces and more).


• Myth: CAD is single file, single user.
  Reality: Today’s CAD supports multi-file, multiuser access; object locking; databases; long transactions and more.


• Myth: CAD doesn’t do 3D surfaces.
  Reality: Today’s CAD supports flood plain analysis, slope analysis, volume calculations, draping, overlays and more.


• Myth: CAD data is file based.
  Reality: Today’s CAD supports storing data in files, SQL databases and external GIS data repositories like Oracle.


• Myth: CAD is for creating paper drawings.
  Reality: Today’s CAD merges design and GIS data with outputs to paper, desktop, Internet and mobile.


• Myth: CAD does not support raster.
  Reality: Today’s CAD supports raster/vector overlays, vectorization, image processing and GIS analysis.


• Myth: CAD doesn’t understand geographic coordinates.
  Reality: Today’s CAD supports thousands of datum, projection and coordinate systems.


• Myth: CAD requires you to import/convert other CAD and GIS data.
  Reality: Today’s CAD supports connection to many data formats without import/export and conversion.

Avoid being a secret agent. Please check-out AutoCAD Map 3D and AutoCAD Civil 3D for more information about the reality of today's CAD and it's ability to integrate CAD and GIS data and workflows. Spread the word.

How to use Negative Distances in your Geospatial Buffer Analysis

Geospatial buffer analysis involves generating a polygon at a specified distance from a proposed feature to determine proximity. For example, a 100m buffer around a point feature creates a circle with a 100m radius. Similarly, a 50m buffer around a polygon feature creates a larger polygon – a polygon that encompasses the source feature.

However, did you know that you can also use a negative distance to create a buffer? That’s right! When you use a negative distance, such as -25m, to buffer a polygon feature, the result is a smaller polygon – a polygon that is inside the source feature.

Consider the following example where the objective is to determine the area of shoreline habitat available for a certain species of wildlife. The species in question has been observed not to forage beyond 100m from shore and includes a riparian buffer of 25m as part of its habitat. To compute the total area of habitat available to this species requires the creation of two buffers and a polygon overlay operation. The first buffer (ie BufferOutside25) is created at a distance of +25m and represents the riparian buffer. The second buffer (ie BufferInside100) is created at a distance of -100m and represents the forage extent. A polygon overlay analysis of type subtract is then used to determine the zone of available habitat where:

HabitatZone = BufferOutside25 – BufferInside100

The total area of habitat available is equal to the area of the zone of available habitat (ie HabitatZone).
