3 Steve's Winery

We are grateful for a budding collaborative effort between award winning and the Drone Tech Program. In a similar manner as our own vineyard, we are currently conducting overflights at 3 Steve's seven acre three varietal estate vineyard as an additional method for crop management. Below are monthly aerial images

Monthly Data Sets

Below are a selection of our monthly data sets. There are only 2 types of data available:

• RGB are color orthomosaic images in a non-compressed "tiff" format.
• NDVI are agricultural indexes saved a non-compressed "tiff" format.
• Zonal Statistics are a quantitative representation of the NDVI index, each zone is a 8' wide by 6' delineated box overlayed upon the rows, these boxes mimic a single vine, in this case there are 72 rows that contain 5,972 areas of data. 

• Common statistics that we can visualize:

  • Count: count the number of pixels (a proxy for biomass)
  • Sum: sum the pixel values
  • Mean: mean of pixel values
  • Standard Deviation: how tightly all the values are clustered around the mean.

   Other statistical methods to view the data

  • Median: median of pixel values (a good representative of the central location of data)
  • Min: minimum of pixel values
  • Max: maximum of pixel values
  • Range: range (max - min) of pixel values
  • Minority: the less represented pixel value
  • Majority: the most represented pixel value
  • Variety: to count the number of distinct pixel values
  • Variance: how far a set of numbers is spread out from their average value.
