AirGeoX

Over the next few weeks AirGeoX will release results of a #drone #spectrometer test flown over a trial area with very low counts, to test the sensitivity and signal to noise limitations of the system. The primary benefit of drone #radiometrics is a lower flight height, which produces a significantly smaller footprint and therefore higher resolution data. The footprint is reduced from approximately 100m for a plane flying at 50m altitude, down to 30-40m for a drone flying at 20m altitude. Flying a plane at a tighter line spacing such as 25 or 50m won’t increase the resolution as the footprint is much wider than the line spacing, the only way to achieve high resolution is with a drone flying at a low height with a tight line spacing. The number of counts increases with decreasing height, however this is offset by reduced crystal volume on the drone.

The AirGeoX crew have broken the company record for the most kilometres flown in one day flying the #drone plane in South Australia. The total flown in one day was 514.8km with the drone in the air for 7 hours and 46 minutes.  Well done to the crew who flew at night to keep out of the extreme heat thanks to the night ops certification AirGeoX has obtained from #CASA. I’m sure the records will continue to tumble as AirGeoX further develop unmanned aircraft capabilities. #dronelidar #dronetechnology #drones #dronemapping #magnetics #lidar #magneticsurvey #dronesurvey #AerialMapping #Surveying #DronesInMapping #droneservices #dronesurveying

Uranium, Rare Earth and #Lithium Pegmatite explorers now have a new tool available in #australia. AirGeoX is offering ultra high resolution drone radiometrics using a Medusa MS-1000 #spectrometer. The #drone spectrometer will acquire data at a higher resolution over a fixed wing platform at a lower cost than a walking survey.   AirGeoX have chosen the #Medusa MS-1000 spectrometer due to; ·    A large CsI crystal with 1000cc volume, 4 times larger than other drone spectrometers. ·    Ability to acquire and deliver up to 2048 channels at varying sample times. ·    Zero effective dead time. ·    Integrated #RTK GPS, pressure, humidity and temperature sensors. ·    Real time processing which outputs #Potassium, #Uranium, #Thorium and Cesium. ·    Laboratory rather than field calibrations reducing the potential for errors. ·    Radon removal is aided by a modelled radon spectrum. ·    Cosmic background removal by hovering at different altitudes. #Radiometrics #GeospatialData #magnetics #RadiometricMeasurement #RadiometricAnalysis

Listen to Adam Kroll, AirGeoX’s Principal #Geophysicist #VicGold24 talk on Tuesday at 2:05pm on structural #geological mapping using ultra high resolution #drone #magnetics.

Meet AirGeoX's Principal #Geophysicist, Adam Kroll at the RIU Explorers Conference. Adam will be happy to chat about anything geophysics, in particular any #geophysics involving #drones or ground #robots. #geology #geologist #magnetics #exploration #riuexplorers #mining

Can you guess what the #payload we’re testing for below is?  I’ll give you a hint, it weighs 7kg. #Radiometrics #RemoteSensing #GeospatialData #DataAnalysis #magnetics #RadiometricMeasurement #Geospatial #RadiometricAnalysis #drone

When flying a #drone #magneticsurvey it’s cheaper to use a plane than a multirotor, but you don’t want to sacrifice the quality of the #magnetic data with excessive height variations adversely affecting the quality of the magnetic grid. The magnetic field from a #geological unit decays at a rate of between 1/r and 1/r3 as shown in the example below.  So if the #magnetometer height varies excessively due to the drone not adequately draping the terrain, it will produce highs when the drone plane is close to the terrain when climbing a hill and a low, when the drone plane is further away from the terrain when flying downhill.  To correct for this a filter is applied called #microlevelling, which reduces the resolution. From testing we’ve determined that the #droneplane has excellent climb and descent performance allowing it to drape slopes of up to ten degrees without adversely affecting the data quality.  The image below shows that the drape height is still within +-2m vertically when climbing and descending a slope on a recently completed job.

Introducing Jeff Kemp, AirGeoX’s Principal of #Geospatial Services.   With thousands of hours of #drone, fixed wing radio controlled aircraft, manned aviation and glider experience combined with a geospatial career spanning the #mining, #consultancy and tertiary education sectors, there is no one more qualified for the role. Jeff has been responsible for developing AirGeoX’s ultra high resolution #photogrammetry and #Lidar VTOL plane drone platform to an extremely high standard. Jeff is keen to speak with clients about their geospatial problems or services they need fulfilled.  A combination of Jeff’s depth of knowledge with AirGeoX long range, long endurance high resolution platform are sure to be able to produce an answer. #lidartechnology #dronelidar #dronetechnology  #lidarmapping #AerialMapping #Surveying #DronesInMapping  #LidarInnovation #SurveyingTech #GeospatialData 

The capabilities of #drones are steadily increasing.  A capability developed recently that is well suited to #geophysicalsurveys is a vertical take off and landing (VTOL) plane.  AirGeoX’s plane has a flight time of 1 hour with the magnetometer bird at a cruise speed of 70km/hr for a range of 70km per flight.   AirGeoX typically acquires 400km of data per day with this platform, significantly reducing the cost per kilometer.  Now you can obtain ultra high resolution, low altitude #magnetic data at a lower price. The survey shown in the video was flown with the mag bird at 17m altitude.  AirGeoX have two crews with 4 planes operating across Australia.  Ensure your company asks AirGeoX to quote your drone #magneticsurvey to know that you’re receiving the highest quality data at a reasonable price. #lidartechnology #dronelidar #dronetechnology  #lidarmapping #AerialMapping #Surveying #DronesInMapping  #LidarInnovation #SurveyingTech #GeospatialData 

The density of #LiDAR points per square meter is important for applications, such as mapping the locations of historical mine workings and mapping geological outcrop under vegetation and mapping a surface model without vegetation for environmental, planning or engineering purposes. The denser the LiDAR points, the greater the number of points that will hit the bare earth and therefore accurately represent the bare earth. For densely vegetated areas, LiDAR is the only solution to recover a digital terrain model (DTM) and for moderately vegetated areas, LiDAR will produce a far more accurate #DTM than using photogrammetry and removing vegetation within software which will create voids in the DTM data and/or interpolate the surface of the voids from surrounding terrain data. The example below was collected with the AirGeoX Hexacopter, flown 60m above ground level, flying at 30km/hr. The point count over a 55Ha area was 450,000,000 points. The images below are RGB colourised LiDAR returns. You can see the bare earth under thickly vegetated trees with high precision right up to the tree trunk with no gaps. If you need a #digitalterrainmodel created under vegetation, contact adam.kroll@airgeox.com for more information. Also contact Adam for any #drone #magnetic work,  crews are in New South Wales and South Australia early next year. #lidartechnology #dronelidar #dronetechnology #lidarmapping #AerialMapping #Surveying #DronesInMapping  #LidarInnovation #SurveyingTech #GeospatialData
