UAV-IQ utilizes drones to collect multi-spectral imagery of agricultural fields to analyze crop health and assist farmers in improving yields. The document demonstrates for a vineyard client how UAV-IQ analyzed high-resolution NDVI imagery at the block and vine level, identifying areas of differing crop vigor that could indicate stress or soil issues. A viticulturalist's analysis summarizes differences between blocks in canopy size and cover crop treatment, and recommends early-season ground truthing of anomalies found in NDVI imagery to determine if interventions could aid crop development.

2. Introduction
UAV-IQ utilizes unmanned aerial vehicles (UAVs) to collect multi-spectral imagery
to assist agricultural clients make the critical decisions that dramatically affect
their bottom line. When properly utilized, the products developed by UAV-IQ
support cultivation and harvesting techniques that have provided double and
triple-digit returns for early adopters of the technology.
UAV-IQ is an early-cycle entrant into the precision agriculture industry offering a
unique, cost effective, full service solution that utilizes data collected from
unmanned aerial vehicles to provide actionable, high resolution imagery and
analysis delivered through mobile enabled platforms to improve crop yields for
vineyard owners.
Why UAVs:
 Low operating costs
 Fly under cloud decks
 Fly lower to get better results
 Resolution as high as 2 cm/pixel
 Computer controlled collection
 Interchangeable sensors
 Operators can adjust flight patterns on site
What is NDVI?
 NDVI stands for Normalized Difference Vegetation Index
 It analyzes the reflectance of near-infrared and visible light off vegetation
 Serves as an indicator of crop health (vigor)
 Healthier plants reflect more near-infrared light
 It can tell you how healthy crops are
– row by row, vine by vine, plant by plant
Detect what the naked eye can’t see…

14. UAV-IQ’s Viticulturalist’s Summary Analysis
Overall view shows 5 distinct blocks. The large one to the south has more green
canopy either because it is a larger trellis type or more advanced canopy. The 2
smaller blocks in the middle do not have much canopy and in this overall view the
color is mostly from the mowed down cover crop (yellow) or disked in cover crop
(brown). The top block looks similar to the bottom block.
Looking at the 4 areas zoomed in on.
Area 1- There is an obvious area of green cover crop re growth which could mean
a leak.
Area 2- Brown patches are the ground and showing areas of missing vines.
Area 3- There is a section which looks likes like it could be a swale, greener areas
look like cover crop regrowth. Vine canopy looks to be a little bigger.
Area 4- Larger block has much more vigorous or more mature canopy then
smaller block at the top. Area in larger block with more yellow cover crop showing
looks like a weaker area, possible soil difference.
The quality of the images is quite good and gives good detail. With the actual iPad
app these areas that show up as different on the NDVI scale within blocks could
be zoomed in on and then located for field ground truthing. I think these early
season images would most likely be used for doing some basic field ground
truthing early in the season to see if differences in canopy, vigor are areas where
early interventions might help with crop development. With the app you could go
to each of these areas in the field take notes and photos and determine if further
investigation is needed. Early season on the canopy vigor differences between
blocks may be due to variety, canopy and it looks like here what you decided to
do with the cover crop. Because the canopies are not very developed yet most of
the color is due to the cover crop where it is showing up yellow and the ground
showing up brown.
