PEIView

  • Fast data verification for PicoEnvirotec (PEI) binary data format files
  • Data Export:
    • ASCII format for use with standard data base applications
    • Geosoft GBN format for use with OASIS-MONTAJ data processing software
    • KMZ (Google Earth)
  • Simple data correction / editing
  • Magnetic compensation (compensation coefficients have to be already prepared with PEIComp program)
  • Stripping Ratios and Window Sensitivities calculations
  • Radiometric data accumulation
  • Spectral windows generation (ROI)
  • Flight log generation :  text file that can be exported to MS Excel. The file comprises information about flown lines, distance, timing, etc.
  • Files segmentation and joining
  • Data Import from ASCII format into PEI binary data format

Data Presentation

Numerical data is presented in a chart as an analog type trace. Data channels can be observed in individual and/or  multiple channels charts.  The data  can be also presented as  a table.

Variety of functions can be applied to a data channel:

Basic channel transformation functionality
Function Usage
First Digital Derivative time data channels quality control
Fourth Digital Derivative noise level  evaluation in magnetic data
Vector applied to 3-axis fluxgate magnetometer data to calculate field vector
Gradient calculation of magnetic field gradient (vertical or horizontal)
Distinction helps to find repetition (if any) in acquired data (quality control)

 

Spectrum View is designed for spectrometer data visualization. Data change over time is presented with colored spectrogram. One time spectrum is displayed in a separate chart. Accumulated spectrum can be optionally displayed. Spectral windows (ROI) can also be oserved in this view
