4. Advantage of this type of aerial photographic camera

Since May 2016 the company AAC first in Ukraine and one of the first in the world to use a wide-format digital aerial photographic camera Vexcel UltraCam Eagle Prime manufactured by Vexcel Imaging GmbH. This camera has a number of advantages over the previously used Vexcel UltraCam-X. Significantly increased the size of the panchromatic image, which makes it easier to perform the scope of work and increased productivity, reduced weight and dimensions of the camera and the system of interchangeable lenses with focal lengths of 80 mm, 100 mm, 120 mm and 210 mm makes the camera versatile and unique.
As used in the touch matrix block design with wide dynamic range (16 bits / pixel) provides a great opportunity in the processing of raw data, allow for a good elaboration and the stark shaded objects in the pictures, show good results in high-contrast conditions.
Output photos can be used for solution of wide circle of problems with minimal costs for their subsequent processing, namely, for:

  • Topographic and cadastral mapping within the entire range of scales;
  • Production and updating of map materials;
  • Building orthophotos and 3D-models of terrain;
  • Solution of engineering survey problems;
  • Estimation of emergency aftermaths and for monitoring of emergency situations.

Usage of the near infrared range channel expands fields of aerial camera application, in particular, its using in forestry and agriculture, geology, ecology, biogeochemistry etc.
Such advantages as absence of grains typical for film aerial cameras, as well concurrent film defects and refusing from necessity to purchase expensive materials, use time-consuming processes and turn to digitizing, reduce expediency of applying film photographic aerial cameras to nil.

4. Advantages of this type of airborne laser system

Beginning from the spring period 2010 the “Aerogeoinformatikaтм” Company is the first Ukrainian one, which operates its own on-board laser scanning system of the similar class.
The ALTMGemini system includes the branch-unique completely computer-aided technology named as ContinuousMultipulse(CMPTM). This technology makes its possible to overcome loss of data connected with limitation of certain combinations of frequency pulses and ranges intrinsic to multi-pulse systems.

 

Laser scanners of the ALTM class provide:

  • High geodesic accuracy  of findings received with the aid of laser-sensed location imagery and its high efficiency;
  • Opportunity for operative mounting of equipment on aircraft board;  
  • Mobility of entire aerial-imagery system and land-based means of data post-processing;
  • The technological cycle, which is short in comparison with other aerial-imagery technologies and comprises  the whole period from beginning of equipment mounting  on the aircraft board to receiving final results;
  • Practically full absence of land-based geodesic operations;  
  • Opportunity of operation in night time and in any season of year;  
  • Opportunity of laser-scanner integration with digital aerial photographic cameras, hyper-spectral  scanners, infrared imagers and other onboard sensors;  
  • Opportunity to use medium and light aircraft (equipment can be mounted both on  external suspension and within fuselage if the proper dimensioned port being available);
  • Opportunities of operator control over received data and operative operator-initiated changing of modes and aerial-imagery parameters  during flight;
  • High economic efficiency even in those conditions, when applying other methods of aerial photographic imagery is very difficult, impossible or restricted by seasonal factors (the landmark-free terrain,  continuous foliage, very «flat» relief etc.);
  • Fixation of 4 reflection at most per one radiated pulse (for example, such fixation besides ground surface makes it possible to  mark out basic plant storey and receive data  about  the true relief even under tree crowns,  in forest etc.);
  • Aircraft-roll compensation etc.

Advantages of the ALTM GEMINI laser scanner:

  • The multi-pulse technology is applied. It provides frequency of probe pulses in the amount of 157 kHz at most;  
  • High scanning  frequency (70 Hz at most);
  • The intellectual control system of laser scanning operation automatically  regulates frequency of laser probing pulses, thereby the problem of ranging ambiguity is solved;
  • Receiving high density 3-D data of  high accuracy;
  • Opportunity to use device at night;  
  • Realization of independent channels for measuring coordinates and intensity in absolute coordinates with reciprocal accuracy of measurements between pulses in the amount of 5 cm at least;  
  • Performance of aerial imagery of the area object, when conducting aerial-imagery operations for manufacturing of large-scaled cartographic products (1:5,000 and larger), amounts to 1,000 square meters per less than  12 flight hours and is provided with opportunity to output the digital terrain  model within 24 hours after aerial imagery finishing;  
  • Ranging to object independently on type of its surface.  

Airborne Laser Scanners of the ALTM class are used for:

  • Large-scale topographic mapping in scales of 1:500, 1:1,000, 1:2,000 and smaller;
  • Building of digital relief models (DRM), digital terrain models (DTM), and 3-D digital models;
  • Solution of wide spectrum of applied problems including those ones in the field of  oil and gas industry, land management and cadastre creation, engineering surveys, inspection of power lines and other line objects  (oil- and gas pipelines,  motor-roads, railways etc.), in the field of forestry, ecology, prevention and monitoring of emergency situations etc.
