archaeologist are finding more ancient metropolis and mislay human settlements than ever before . And it ’s all thanks to novel imaging technologies commonly used in surveillance . With extremely - accurate measure from artificial satellite , drones , LiDAR , and more , archeologist are making discovery that were once impossible .
Patricia Murrieta - Flores , an archaeologist at Lancaster University in the U.K. , told io9 that archeologist have long been early adopters of new technology : “ Since very early on , archeology has learn and adapt theories , method and techniques from other field , such as geology , geographics and chemistry , among many others . ” Though a former generation ’s archeologists might have carry trowels , dustpans and function , these days they ’re more likely to be using radar .
Over the preceding thirty years , the field has rapidly evolved , and now make use of satellite imaging , priming - penetrate radio detection and ranging , figure imaging ( CT scans ) and even machinelike drones . Here are some of the discoveries these undercover agent technologies have made potential .
The View From Above
Before archaeologists can excavate a new discovery , they need to observe it first . In the past , this could demand focus over historical record and maps . Nowadays , archaeologists have added another tool to help them locate areas of interest : Satellite imagery .
In fact , research worker have made important discoveries just by seem at Google Earth effigy . In 2011 , archaeologists used the democratic 3 - D mathematical function program tosee what archaeological secrets are inhume in Saudi Arabia — they find that large part of the body politic are rich in archaeological remains that may be several one thousand of year old . And last year , planet archeologist Angela Micol made waves when she reported that she found Google Earth anomalies thatmay be pyramids buried in Egypt(her title drew a good deal of criticism from other scientists , but Micol and others areworking to determine what the structures in the image really are ) .

Other archaeologists are using satellites equip with infrared cameras , which areable to peer beneath the ground . “ blank archaeologist ” Sarah Parcak is a trailblazer in using infrared planet imaging for archaeology . A couple of years ago , Parcak and her team used the engineering to identify more than 1,000 tombs , 3,000 settlements and up to 17 potential buried pyramids . Parcak ’s work also reveal swallow up city streets and houses in Tanis , the famous ancient Egyptian city feature in “ Raiders of the Lost Ark. ” In aninterview with the BBC , she said , “ Indiana Jones is sure-enough school , we ’ve moved on from Indy . Sorry , Harrison Ford . ”

Last year , scientist found a new way to practice satellites to key out buried settlements — bysearching for anthrosol , a type of ground lead from long - term human activeness . Archaeologists have used anthrosol detection on the ground level for years , so research worker at Harvard and MIT develop an automate system to seek out anthrosol in multi - spectral orbiter images . With the proficiency , they mapped about 14,000 Mesopotamian colonisation sites , which span some 8,000 years .

Archaeologists can also use satellite imaging for more than finding sites to investigate . Elizabeth Stone , an anthropologist at Stony Brook University , employ satellite - based monitoring toassess the level of looting and death of archaeological web site in Mesopotamia(modern - day Iraq ) . Recently , other scientist have used the technique toinvestigate archeological looting in Peru .
Finding a Lost City with LiDAR
Though satellite imagery is important to archaeologists , they may be trumpedby another airy imaging technique . Arlen Chase , an anthropological archaeologist with the University of Central Florida , thinks LiDAR ( Light Detection and Ranging ) is a “ substitution class auto-changer ” for archaeology . “ What LiDAR has done is give us ascendency of space , the direction tuner C geological dating has given us control of time , ” Chase told io9 .
With LiDAR , researchers use low - take flight planes to send out laser pulses to the ground — by analyzing the pulse reflected off the earth and the flora , they can then make 3 - 500 topographical single-valued function of the ground aerofoil . For over two X , Chase and archaeologist Diane Chase ( his wife ) conducted countless primer dispatch to map out the ruin at Caracol , an ancient Mayan metropolis just outside Belize . When the couple usedLiDAR on the realm a match years ago , they were able to represent around 80 square international nautical mile of the ruin in just a few days — about 10 times the area they previously mapped in their 20 geezerhood of workplace .
Other scientists are also overtake on to the usefulness of LiDAR for archaeology . Earlier this yr , archaeologists used the technique on the rain forests of Honduras in Central America , anddiscovered what may be the legendary La Ciudad Blanca , “ the White City . ”

“ Nothing recent has been as impactful as LiDAR , ” Arlen Chase said . “ It has just moved us onward by leaps and bounds . ”
Murrieta - Flores supply that LiDAR is enhanced bygeographic selective information systems(GIS ) . These are computer software systems for coiffure geographical data point in stratum — for example , you might have a layer of LiDAR information on top of a mathematical function express local water systems , which could help you track where ancient community were most likely to build for be in areas fed by streams . She excuse :
These technologies make a huge dispute for archaeologists today because they appropriate you to mix very large volumes of information , which was antecedently impossible . They also activate the desegregation of very disparate sources , such as diachronic map with modern data , archaeological data and others . They help you to not only figure and integrate all this in a very efficient elbow room , but also to analyze and therefore describe in a quick and expedited way the patterns underlie such datum . In addition , you may also recollect data about your data with simple queries . Before the evolution of GIS , the traditional mode of record findings at a landscape scale was to just draw point on a paper map . This would only allow you to see the dispersion of website or findings but nothing else . now Gi project integrate huge amounts of ascribe info that get to it possible to do spatial depth psychology to identify trend and pattern .
In 2010 , University of California Los Angeles archaeologist Michael Harrower used GIS technology to investigate theorigins of irrigation in Yemen . And when GIS is combined with3D - modelling technologies , scientists can create a kind ofvirtual transcript of intact sites .
Learning Without Destroying
A major concern in archeology has always been the potential damage because of excavation — Indiana Jones may have tramp down through ruins without a care in the world , but actual - lifespan archaeologist adjudicate their best to preserve the remnants of the past as best they can . In recent years , scientist have begin testing out quite a few unlike non - invasive technique to analyze archaeological web site .
terra firma - penetrating radar , or GPR , allows archaeologist to see what ’s underground without ever call for to toil . Back in 2002 , researchers successfully used GPR in Petra , Jordan tolocate underground structures and conduct tardy digging . multitude have also used the proficiency extensively for theDuffy ’s Cut Project , which seeks to learn more about the liveliness of Irish immigrant who were buried in Duffy ’s Cut , Pennsylvania almost 200 years ago . And recently , scientists used GPR to try tomap undiscovered ruin in Pompeii — they believe the technique could be used to provide elaborated mapping of the subsurface ruins , which will believably never be turn up .

Last class , archaeologists found that they could nail and distinguish areas devote to prehistorical midden ( trash dump ) and plazas by measure the varyinglevels of phosphorous in the grease . At their field of study website in Pickaway County , Ohio , where a village once stood around 700 years ago , the researcher identify a U - shape ring of high phosphorus concentrations , which indicate a village midden , enclose by an region of low-toned phosphoric concentrations , which stand for a plaza where ceremonial took place . In their paper , the authors note that such noninvasive proficiency are authoritative because excavation is often “ expensive , time - squander , and may lean counter to conservation value-system ” ( though other scientists have stressed thatnoninvasive technique can never replace excavation ) .
The use of automaton has also found its way into archeology . Most notably , scientists havesent petite robots into Egyptian pyramidsto check out chamber they could never get to themselves . In 2011 , the automatic adventurer Djedi captured the first figure ofenigmatic markings on the wall of a small chamberin the Great Pyramid of Giza . Last year , archaeologists used another golem tobuild 3 - D mathematical function of ancient Rome ’s largest sewerage system(called Cloaca Maxima ) . A few months ago , another team guided robots underneath the Temple of the Feathered Serpent , an ancient Great Pyramid in pre - Latino metropolis of Teotihuacan , anddiscovered century of mysterious spheres — nobody make love what the purpose of the orbs are yet .

Of course , to really learn about ancient culture , you need to meditate the remains of multitude from those finish , not just the venue . As we discourse in this objet d’art abouthow scientists study mummies , there are number of non - destructive techniques archeologist are now using to teach about human ( and animal ) remains , include CT CAT scan , flock spectroscopy , DNA analysis and protein analysis . And earlier this month , a conservator at the University of Stavanger ’s Archaeological Museum in Norway devised a way todetermine if ancient bone curb any DNA , a technique that could help scientists avoid knock off fourth dimension and money carry out DNA analyses on remains that contain no inherited material .

The Future of Archaeology
As scientist and engineers acquire young technologies , archaeologists will no doubt be agile to adopt them . So what ’s in store for archeology in the approximate future ?
Chase is excited to see where LiDAR goes from here . “ It ’s still expensive to practice , ” he said . “ But there will be newer discoveries that eliminate certain less - complex models that we have been using to construe the data . ” He also remember new technique to better see things buried underground will come along .
Murrieta - Flores noted a mates of interesting tools that are currently in the works , such asReflectance Transformation Imaging(RTI ) . The method essentially enables you to re - get off an imaged object from any angle and enhance its surface attributes . Researchers are currently using RTI to try out todecode the existence ’s oldest undeciphered text . “ One of the most important aspect of RTI so far is that it is very easy to follow through and everything has been developed as open source so country with less resources can easy follow it , ” she said .

Murrieta - Flores is also excited about the use of “ Tangible User Interfaces ” in archaeology , in which citizenry manipulate digital information through physical environment . For instance , researchers designedArcheoTUI(video below ) to help archaeologist piece together fragment of fractured archaeological objects .
