Palmitopamba: Tola 5 KAP

Wed, 28 Jul 2010 00:41:10 Z

"In July 2010, archaeologists began excavations on a series of tolas (mounds), in the Palmitopamba area of Northern Ecuador. The tolas frequently mark burials but not always. The range in size from a few meters in diameter to massive earthworks that can dominate the mountain tops. They were built bu the Yumbo culture. I was working on a nearby project but helped map several of their sites. At this location, I did both Total Data Station (TDS) and Kite Aerial Photography (KAP) mapping."

"Test aerials from initial flights of my new hexakopter UAV. It is a very promising vehicle for mapping our world from low altitude."

Sorry to bother you, but what is the nadir issue?

Cerro Chino Petroglyph Site (Large Panel)

Wed, 20 Jan 2010 20:44:51 Z

"Cerro Chino is a relatively unknown petroglyph site located near (somewhat) Ojinaga, Mexico. The synth is an atempt to extract a decent 3D point cloud from the photos."

Here is an animation showing the same data:

Definitely a cracking methodology you're developing there Mark. I'll have to try once again to get my head round the vagaries of Meshlab.

Photosynth to DEM - Test

Tue, 22 Sep 2009 21:53:51 Z

"This is part of the synth that I created a digital elevation model from using Photosynth and a few GIS tools. The photos were collected via Blimp Aerial Photography (BAP) You can see a short animation of the data here: http://www.youtube.com/watch?v=j_Iqs8go75k&feature=channel_page"

This is inspirational! It completely rocks my world.

Meyers Spring Pictograph Site

Wed, 09 Sep 2009 07:34:44 Z

"Meyers Spring Pictograph Site is located near the town of Dryden in West Texas between two ancient Comanche War Trails. The rock art is found on a limestone cliff face adjacent to Meyers Spring, one of the only stable sources of fresh water for many miles. The oldest art found at the site consists of the prehistoric Pecos River Style (2000 to 4000 years old). Most it has faded or has been covered by early historic (150 to 400 years old) pictographs that now dominate the site. The latest pictographs found are some the best preserved in North America and appear to chronicle the earliest contact between European and the native peoples of this area. Several native groups are known to have visited the area and include Apache, Arapahoe, Comanche, Kiowa, Kiowa Apache, Pawnee, Ute, and an earlier group we call Lower Pecos people. An United State military outpost named Fort Meyers(or Myers) was established near the spring to try and control the native peoples in the late 1800s. The fort and spring were named after one of the black Seminole soldiers who served under Lt. John L. Bullis. Most of the interpretations of the rock art listed in the highlights are those of Reeda Peel, a rock art specialist at the Center for Big Bend Studies at Sul Ross State University in Alpine Texas. As with any artwork, a lot of what it "means" is speculation. Unless otherwise noted, the photos were taken on September 5, 2009 by Mark D. Willis. I have added some historic photographs for reference. Those are listed at the end of the highlights. Anyone wishing to visit the site can contact the non-profit Rock Art Foundation ( http://www.rockart.org ) about one of their twice a year tours."

Tony, thanks for the interest. Once I'm done testing, I'll add the details. I wasn't paying attention and should have made it UNlisted.

Another Tres Yonis Synth

sir ivar, do you have any laser scan data to compare? I was involved in a rock art project for 3-4years and this involved scanning several carved stones. I might be able to get hold of the data. I’d need to capture additional imagery for a comparator synth though, we just have photogrammetric stereo pairs and the resultant point cloud wouldn’t be dense enough.

I’ve not worked directly with Jim Chandler, but he did advise the above project and calibrate the cameras. Some of the projects work fed into his research on low cost photogrammetric approach and camera calibration.

Is the email on the You Tube movie still current? If so, I’ll drop you a line. Cheers Rich

"This is a Kite Aerial Photography project that I did in Ecuador in 2007. The site was an Incan site that the Spanish converted into an Hacienda."

Stellar!

Would you mine geotagging this?
