The Applied Technology Council (ATC) has developed a free web-based tool that finds site-specific wind speed using the GPS coordinate system. With this tool, wind speeds are interpolated to the nearest mile per hour based on the wind contours on the maps. The platform is Google Maps; and either street maps or satellite images can be used to locate a specific site. Wind speeds are provided in 3-second-peak gust speeds for the three Risk Category maps provided in ASCE 7-10 and for 10, 25, 50 and 100-year return periods. Test out the new tool by visiting www.atcouncil.org/windspeed/index.php.
