Wind design on hillside and slopes - tools

[Subject Prev][Subject Next][Thread Prev][Thread Next]

I received a Garmin Nuvis 205W GPS for my car from family. The prices are dropping and it was purchased for $100.00 locally and is normally over $200.00. I discovered that it is not only accurate for pedestrian use to find a cache from a game posted on the Garmin website where coordinates are provided to help you locate a point of interest cache, but that the device also maintained a proper elevation measurement while driving up into the mountains. In the current wind force analysis of ASCE 7-05, a hillside structure needs to be analyzed for wind traveling up the slope. The bottom and top  elevation of the hill needs to be identified as does the site location. Not only is the unit worth the money for use as a trip guide, it can be used while walking around and gives accurate results of building site locations within a few feet +/- as well as accurate elevation information. This helped me save a bit on a project that I had which required this information. Yes, you can obtain the same information on MSN or Google Earth, but it if you use a GPS system, I am assuming that it is a standard feature on virtually all units. For about $100.00 – the 205W was a bargain.
