  1. 1. Unmanned aerial vehicles New possibilities using UAV in remote sensing of the environment Jakub KARAS
  2. 2. RPAS - remotely piloted aircraft system UAS - unmanned aerial system UAV - unmanned aerial vehicle ...is an aircraft without a human pilot aboard. Its flight is controlled either autonomously by onboard computers or by the remote control of a pilot on the ground or in another vehicle
  3. 3. ADVANTAGES: • significantly cheaper to operate (compared to usage piloted machines) • easy handling and mobility • high flexibility for the use of machines in action • possible to use (takeoffs and landings) even in hard-to-reach areas • low noise operation • resistance - extremely dangerous locations • high resolution images and videos • other potential benefits of the acquisition specific data in connection with the physical microsensors
  4. 4. How to choose right UAS Each Unmanned Aerial System has its own specifics with which we calculate and adjust the selection of the purpose for which it is acquired ...
  5. 5. RPAS/UAS – specifications Copter x wing types Copter - variability of different sensors, limited weight - the use of mapping, through monitoring, after shooting - vertical take-off and landing (some even from hand) - online video transmission from the sensor - manual x automatic flight Wing (Plane) - limited to mapping a predetermined sensor - take-off from the hand or from the ramp - landing automatic (manual)
  6. 6. WING UAV take-off from the hand or from the ramp
  7. 7. SENSORS • RGB camera • Multispectral camera • Hyperspectral camera • Thermal camera • Laser scanner • Specific sensors (gas sensors etc.)

  11. 11. ACTUAL ORTHOPHOTOMAPS Actual orthophotomaps in very high image resolution for small areas * Timber depot in image resolution 7 mm/pixel
  12. 12. Orthophotos according to specific requirements * Průhonice park – orthophoto 3 cm/pixel Current orthophotomaps according to specific customer requirements (different compared to a conventional orthophotos - WMS). Mapping during the low clouds (without shadows), flying the next day depending on the weather conditions, in a short period.. Google
  13. 13. ORTOPHOTOMAPS NIR, NDVI, Thermal actual orthophoto in the NIR, NDVI, thermal imaging, for vegetation indIces, precision farming, application maps for clever agriculture machines * breeding wheat field
  14. 14. ACTUAL MAPPING AND AERIAL MONITORING • Mapping the exact extent of damage in the fields after wildlife
  15. 15. IDENTIFICATION ANIMALS BEFORE HARVEST * Monitoring of wildlife and their position in the agricultural fields the day before harvest

  20. 20. MONITORING NATURE INCIDENTS * D8 highway landslide, textured point cloud Mapping possible immediately after the incident. Visualization of the extent of damage on the basis of the chosen strategy, progress and possible risks. From one flight RPAS - aerial photography, orthophotos, high-resolution point cloud 3D model visualization ... Further options videodocumentation, aerial photos.

  28. 28. IDENTIFICATIONS DRAINAGE SYSTEMS
  29. 29. The possibility of using remote sensing to identify drainage systems • direct identification of lines of drains, fragments until comprehensive drainage systems (DS) using different means and acquisition of various types of data • accurate topologies and determine their actual position • in the field (correction of the project documentation) • Using different outputs and sensors from UAV during different weather conditions
