The Alamo and more

I have been neglecting updates on my website, even though I’ve been doing some interesting work!

2016 has been extremely busy with large projects at the Biltmore in Asheville, NC and in San Antonio, TX (above). I’ve also had a chance to do some design work for two restaurant installations here in Virginia – “The Store” and “Chicano Boy”.

Plus I had a nice show of photographs of Portsmouth Island, NC that has been hanging in Ocracoke all summer.

That’s all for now – just wanted to post something ūüėČ

Neglecting the website/blog has gone on too long. I’ve been doing a lot of work since last fall but none of it has made it¬†onto this page!¬†So, just to break the ice, so to speak, I decided to grab share an orthophoto from a favorite place to many.

This orthophoto was composed of infrared shots of this famous trio of buildings in the heart of New Orleans. I grabbed these when I was visiting the city and looking at the possibility of creating a high res (both spatial and temporal) 3D model of the entire French Quarter for use as a planning and preservation tool.

Anyway, stay tuned and I’ll try to share some of the recent work soon.

Enriching HABS documentation with Orthophotography

HYBRIDIZED 00001a 1 When I am hired to prepare a set of documents to describe the existing conditions of buildings I sometimes try to incorporate older drawings and the like. If I am working with original construction drawings it can be very interesting to see how and where the existing structure is different than the one designed. If I am working with measured drawings of unknown provenance it can be very frustrating to see how inaccurate the drawings are! So as a rule, I only deliver measured drawings that I create from my original site work  since its the only way I know that I can really trust the work and stand behind it.

Realizing how valuable a good set of measured drawings truly is, it is wonderful to consider¬†what a treasure our HABS HAER collections are! These are uniformly drawn to standards generally higher than the profession gets by on, even today. Sometimes I am looking at doing some work on a project and I am fortunate to learn that a HABS set of drawings already exist. This gives me an opportunity to overlay some of my work (with photogrammetrically derived images) onto this “layer” of information in seamless fashion.

I’ve long done this kind of work with rectified photography in a sort of manual approach. I’m discovering that its equally great to “Hybridize” the HABS line drawings¬†with orthophotography as well (derived from 3-D models derived from a scanning process). The images posted here show a recent look at the Cape Hatteras lighthouse on North Carolina’s Outer Banks. The HABS collection of drawings is very nicely done and available to all to explore through the HABS web site (here). The images posted here show how the line drawings can be built upon with technology available today,¬†¬†They become the¬†foundational layer of a living document that describes¬†an important piece of architecture in great detail.
