Learn how to reduce energy costs through off peak irrigation

Phase 5

Satellite imagery is limited by the area required to purchase and the inability to select specify an image date to receive a 1-meter resolution imagery. Satellite imagery resolution at 1 meter is equal to a single pixel per square meter. So, in a typical vineyard you will have 4 pixels (data points) per vine.

Is limited by the inability to specify an image acquisition date. However, unlike Satellite Imagery the area required to purchase is as small as a single field. Typical Fixed Wing Acquired Multispectral Imagery ranges from .5 to one meter in resolution. In a typical vineyard, you will have four to eight pixels (data points) per vine.

UAV Images are limited to the amount of area they can cover in a single day. UAV imagery ranges from 2-5 centimeters resolution imagery. So, in a typical vineyard you will have 20-50 pixels (data points) per vine.

The Report Card shows how the fields are performing. Using Multispectral Imaging H2O Optimizer can measure how the orchard and/or vineyard vegetation/canopy has improved or declined from acquisition date to acquisition date or year to year. These comparisons also provide the number of trees or vines growing or in decline.

H2O Optimizer has developed data analytics for multispectral imagery from high-resolution UAV that can provide enough detail to determine what vines and or trees are receiving either too much or too little applied water based on emitter wear or plugging respectively. H2O then calculates the number of emitters that are worn, and the number of emitters plugging relative to the average. This technique provides precise locations to measure output by an emitter and calculate D.U.

Sensor requires calibration evaluation is on an annual basis. Each year as your tree or vine canopy develops or declines so does its root system, the volume of soil represented by the sensor changes, changing your sensors’ target levels. Sensors should be calibrated annually using multispectral imagery (NDVI) during peak vegetation and senescence (June – September).
