The Dirt

Civil 3D and Archaeology

This past week, I attended the VII International Conference on Easter Island and the Pacific that was held at Gotland University in Visby, Sweden. Held every four years, this conference brings the world’s leading archaeologists together to present papers on Easter Island and the Pacific area.

You may recall that I visited Rapa Nui (a.k.a Easter Island) this past February (see February posts) and was fortunate enough to gain permission to survey for several days on the island. Due to the impression that Civil 3D made on the island’s government officials, I was asked to demonstrate Civil 3D at the conference.

During the conference, I had the pleasure of meeting many of the 160 attendees. I was in awe of the collective knowledge of the group and their passion for Rapa Nui. Clearly there is something seductive about the place. I have only been there once for six short days. Some of these folks have spent their lives and/or careers there. Their passion for the island is evident in their work and their conversations with me—a lowly software geek whose archaeological knowledge comes from The Discovery Channel.

Rarely have I been so nervous presenting in front of a group of people! Fortunately for me, the group was eager to see Civil 3D—specifically its survey, GIS, and terrain modeling capabilities. Archaeology, you ask? How can civil engineering software fit here?

Historically archaeology has been a 2D process. GPS and GIS technology is standard issue, as are paper and pencil for completing hand drawn sketches of sites, excavations, etc. Databases are also frequently created and managed to inventory sites and the artifacts they contain.

I was confident that by showing my audience the GIS, survey, and terrain modeling capabilities of Civil 3D I would gain some converts. For years many archaeologists have used GIS software to map their work. For me, this meant that I could expect questions about the interoperability of legacy GIS data with respect to Civil 3D. Using the MAP functionality in Civil 3D, I was able to demonstrate this was not an issue, since Civil 3D is built on top of AutoCAD MAP 3D.

Archaeologists have also used surveying technology for many years to locate and map their sites. The survey components of Civil 3D, including figures and description keys, provide a perfect set of tools on an archaeological dig—all in 3D. With total stations, GPS, and yes, even hand written field notes, Civil 3D can accommodate. Furthermore, any attribute data (size, age, color, condition, etc.) can be added to each point and then queried or used for thematic mapping purposes.

The 3D terrain models that Civil 3D can create offers a new and powerful benefit to archaeologists.  Historically the creation of contours, cross sections, earthwork calculations, and drainage patterns has all been done manually with paper and pencil. I think it is fair to say the survey grade, 3D models that Civil 3D can create and analyze made a big impression on many of the attendees.

Clearly its application to archaeology is yet another example of just how adaptable Civil 3D is!

I would like to thank my dear friend Sonia, my new friends with the Easter Island Foundation and Gotland University, as well as the attendees who patiently tolerated my ignorance of all things archaeological.

South Jersey and Harrisburg, PA User Group Meetings

Here's Bill and Tamara from Synergis with a quick recap on the back to back Civil 3D user group meetings we did together last week. My thanks to Synergis and to all the folks from the South Jersey Civil User Group (SJCUG) and the Civil Harrisburg User Group (CHUG).

Thanks guys!

The US Marines are moving to Guam

Last week I stopped in Guam (a US territory) on my way back from Korea, because I had read about a $10-$15B project that will move the Marine Corps from Okinawa to Guam.

I was given the opportunity to speak to many of the project stakeholders on Guam. Representatives from the government of Guam, the US Navy, the US Air Force, the EPA, Guam Power, and Guam Water attended.

I spoke about leveraging technology, and the importance of standards and process as data moves from contractor to stakeholder and vice versa. Once again, Civil 3D with its survey, design, construction, and GIS capability was a big hit.

The governor knows his population is going to double. Best estimates say some 30,000 new residents will arrive in Guam over the next decade. The existing infrastructure, roads, utilities, etc. require improvements to meet the coming demand. The US Navy and the US Air Force each have considerable work to do in preparation for the arrival of the USMC, its gear, and its dependents.

Check out a video post I made from the island of Saipan. If you are a WWII history enthusiast you'll like this one:
