Many years agone I briefly worked equally a route surveyor. The project involved walking 5 to 10 miles of route a day, painstakingly criterion every route irregularity (e.g. potholes) as well as recording the information on a handheld computer. The information was as well as then used past times the local ascendancy to position the close damaged roads as well as schedule route repairs.
This was inwards the days earlier the availability of commercial GPS units thus everything had to last measured past times mitt as well as criterion wheel. These days I imagine the project could last done at i hundred times the speed alongside cars fitted alongside a GPS unit of measurement as well as an accelerometer. Or you lot could fifty-fifty practice it past times bike.
Varun Adibhatla has created an interesting visualization of this sort of route surface survey carried out using a cycle as well as an iPhone's accelerometer. Bumpiness inwards NYC shows the trail of a bicycle journeying inwards New York. The bike's runway on the map is colored past times 'bumpiness', alongside the close bumpy sections colored inwards red.
Many laptops these days too bring built-in accelerometers. The Quake-Catcher Network realized that they could practice the world’s largest as well as densest earthquake monitoring organization but past times using the information from accelerometers inwards the world's laptop computers.
The Quake-Catcher Network links participating laptops into a unmarried coordinated network that tin forcefulness out honor as well as analyze earthquakes faster as well as ameliorate than always before. QCN uses Google Maps to present the information collected from participating laptops as well as from participating desktop computers alongside USB sensors. The map too shows the latest USGS reported earthquakes.
