  1. Michael, The site you referenced is most elegant in its design and performance. I selected about 500 points in a test area I was fairly familiar with and exported the gpx. I inspected the gpx output file with a text editor and it was flawless. Impressive!!! Being new to Chief Architect I had to grope around a few times with the gpx import process, but I finally knocked it out and rendered a decent surface. Next task is to double check a few reference points with my altimeter to build a little confidence with GeoPlanner/CA. I also took a screen scrape of what appears to be 1 foot contours out of the CA topo page and superimposed the lines on a Google Earth aerial. From what I can see and what I know of the land, it came out rather well. Thank you for the assist in helping me find that tool! I greatly appreciate you taking the time to help!!! Bruce
  2. I am working on a new property where we will need a home and several buildings. Detailed Topo Elevation data seems hard to find as the area is rather rural. Having built a spreadsheet of test XYZ data and importing that into CA/Home Designer worked quite quickly to produce a terrain surface. Since that worked well, I would like to take a handheld GPS and walk the property and develop a elevation point grid to have a relatively accurate terrain model to design on. The elevation over the property likely varies about 100 feet. An minimum accuracy of within 5 feet would work for this project. I would be interested to hear from users that have tried using GPS points to build terrain models and get any info as to how well it worked. Possibly what GPS units were used as well. I would really appreciate any suggestions and advice about how to gear up for this so as to avoid reinventing the wheel :^) Thank you! Best regards, Bruce
