Thanks for your interest. Google and NASA WorldWind doesn't cover the area with the fish weirs in high resolution imagery yet. The LANDSAT imagery isn't of high enough resolution to see anything but the coarsest of the large causeways and canals of the Baures Hydraulic Complex. You can check this out by moving due east from the town of Baures (search "Baures, Bolivia" which is a bit off the actual town on a Google place search) between the first river (San Joaquin River) and second river (San Martin River) before the forests and border with Brazil (the Guapore or Itenez river. I have a survey and mapping project in the Baures Hydraulic Complex this summer and another project between Baures and the Rio Mamore. We have our own unpublished GIS of the region based on aerial photographs, declassified satellite imagery, and LANDSAT ETM imagery which shows most of the earthworks. We will check the accuracy of the GIS this summer. Once Google covers this area, our GIS will probably be obsolete. Some of the ring ditch sites, small blocks of faint raised fields, and a few long canals show up on the scattered high rez Google that does exist for the town of Baures and a few forest islands to the north, NW, and WNW. You can check out high rez photos of the fish weirs from a low flying Cessna on my website. You can also see a brief video segment on fish weirs in the documentary "The Secret of El Dorado" (BBC -2, Horizon Series, 2002). Clark At 01:01 AM 3/7/2007, you wrote:
I've been reading 1491 which cites your research and was curious to actually take a peek at this myself in google maps or Nasa WorldWind. Hoping you can help me out with a specific location that I can then share with my community of geo enthusiasts.
