To get the highest quality final product, you need high quality source data. So, Aerotas has minimum data quality standards that a project must meet in order for us to process your data.

  • Sufficient overlap

    • 75% front 75% side overlap recommended

    • use of terrain awareness on projects with more than 100’ of elevation change

  • Good photo quality

    • Minimum 20MP sensor recommended

  • Proper camera orientation

    • Nadir (straight down 90 degrees)

  • Proper flight pattern

    • Boustrophedonic (back and forth pattern)

  • Sufficient ground control

    • 5 Per flight battery (non-RTK)

    • 3 minimum (RTK)

  • Clear ground control marking

    • Precise center point

    • Visible from altitude

  • Good ground control distribution

    • Edges, corners, and middle, evenly distributed (non-RTK, Distribution still beneficial but not as important for RTK)

  • Supplemental Data

    • GCP file in PNEZD format

    • Rinex data (PPK projects only)

    • Base station observation file (PPK projects only)

There is also such thing as too much data. Excess data causes delays in processing and delays in the field. Things to avoid:

  • Unneccesary crosshatch flights

  • High overlap (higher than 75/75 is considered high)

  • Excessively low flight altitude (lower than 150’)
