I am most impressed with = your work on the GaMa project. Here is a link to a project that I am = partly involved in. We are re-engineering our legal survey plans = registry model to accept digital plan submissions. Land XML has been = chosen as the standard survey data observation information exchange = format. You may find it interesting to look at the quick overview of = the project to date. We are finalizing phase 3 of defining the detailed = business and systems architecture. http://srmwww.gov.bc.ca/dspp/Docs/AGM2004.ppt As a personal home project I have done some research on using elevated = aerial panorama's (up to 25 feet above ground level) for deriving = directions like a low accuracy theodolite. Several images are mapped = together to create an equirectangular map projection. As the image is = conformal, I am able to point to image targets (usually not more than 60 = metres away) to obtain directions from the image. I just tape distances = to obtain scale. I did some internet research and found your wonderful = GaMa program, created a 2D network and adjusted the small local network. = I am amazed at your excellent documentation. I created the GaMa input = file in a spreadsheet and ran the adjustment the first time and = discovered I had a couple of syntax errors. I re-ran the adjustment and = was very pleased with your program results and output file. An = excellent program. The adjustment shows internal angular precision of = about eight minutes sexigesimal units. The derived directions were then = compared to survey accurate measurements which confirmed about an eight = minute average accuracy for the derived directions.
