Many years agone I briefly worked equally a route surveyor. The chore involved walking v to 10 miles of route a day, painstakingly standard every route irregularity (e.g. potholes) as well as recording the information on a handheld computer. The information was hence used yesteryear the local authorisation to position the nearly damaged roads as well as schedule route repairs.
This was inwards the days earlier the availability of commercial GPS units hence everything had to endure measured yesteryear mitt as well as standard wheel. These days I imagine the chore could endure 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 exercise it yesteryear bike.
Varun Adibhatla has created an interesting visualization of this variety of route surface survey carried out using a cycle as well as an iPhone's accelerometer. Bumpiness inwards NYC shows the trail of a cycle journeying inwards New York. The bike's rails on the map is colored yesteryear 'bumpiness', alongside the nearly bumpy sections colored inwards red.
Many laptops these days besides bring built-in accelerometers. The Quake-Catcher Network realized that they could exercise the world’s largest as well as densest earthquake monitoring arrangement precisely yesteryear 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 flame discovery as well as analyze earthquakes faster as well as amend than e'er before. QCN uses Google Maps to exhibit the information collected from participating laptops as well as from participating desktop computers alongside USB sensors. The map besides shows the latest USGS reported earthquakes.
