Laser scanning has helped England do everything from discovering new things aboutStonehengeto plan betterflood substructure . Now , the commonwealth has made the entirety of its massive trove of scans available for free — in part because of petition from everyone from researchers to Minecraft players .
All mighty , so it ’s not just for Minecraft , though it ’s very funny to hear that fan actuallyappealed to the governmentfor LIDAR data to employ in the game . “ Minecraft role player have request our LIDAR information to help them build virtual worlds , ” the Environment Agencywrites , “ the datum could be utile to anyone creating realistic three-D macrocosm . ”
It ’s also for anyone who could profit from a comprehensive , high - res model of the country , let in archaeologists studying Bronze Age burial website , scientists working on clime change , and urban planners .
In fact , England ’s been make its LIDAR datum available for a few years . But last month , it made the entire 11 - terabyte dataset useable for detached through an online portal vein . As the government activity ’s Environment Agency points out , “ that ’s rough equivalent to 2,750,000 MP3 songs . ” As Prosthetic Knowledgeput it this calendar week , “ you’re able to download a state , ” for barren , for any use you want .
What is LIDAR information , anyway ? In simple terms , LIDAR is a scanning system attach to the venter of a low - fly aircraft in rules of order to pulse laser light at the surface of the Earth . This light is reflected back up to the system , where it is measure , creating a true reading material of the 3D shape of the ground below .
As it ’s generate cheesy , LIDAR has become more commonplace . It ’s played a big role in late archaeologic discoveries because it can “ see ” element of the landscape painting that might be concealed by Sir Herbert Beerbohm Tree canopy or obscured by modernistic - mean solar day construction . In particular , it helped researchersuncover a “ lose ” city in the Honduran rain forest last class .
Since administration ca n’t be responsible for analyze all the data it collects , it make sense that they wouldopen it up for public use . This is a growing trend : Minnesota has madeits own LIDAR data availableonline , for instance . Finland has madeits data for some of the country availablea few geezerhood ago , too , along with Switzerland andseveral other countries .
But England ’s datum is very gamey result — it ’s two meters , compared to most four meter - resolution maps — which make it more useful for everyone , from researchers to gamers . You have to make out how to download and apply the files with GIS , but that should n’t be too hard to cipher out .
