Analysis of remotely sensed and ground-truthed data could greatly improve management decisions in regards to crop inputs and irrigation efficiency. (Source: 2 Standard Delivery with Every Order True Color (RBG) NIR (Near Infrared) NDVI (Normalized Difference Vegetation Index) 3 True color: 3 Bands Red Green Blue Near Infrared Band NDVI: Normalized Difference Vegetation Index Calculated using the visible (R) and Non-visible (NIR) NDVI is calculated. You can use any program (ArcGIS, SST, etc…) to calculate the NDVI. The NIR is also known as the CIR as it is commonly “colored” to show healthy vegetation as reddish and progressing down to blue based on the health of the crop 3 The Farming Dollar Crop Inputs Seed Technology Crop Insurance Machinery & Power $205 per acre $18 per acre $103 per acre $92 per acre $32 per acre Storage/Handling Image courtesy of photosteve101 4 Cost of farming has continued to increase especially with crop inputs Capital stretched thin $1.70 per acre for $205 per acre 4 5 Capture images from multiple geographically disperse locations at the same time with high quality 5 Deployed Camera Systems 6 2012 FOB’s Pilots are sub-contractors and can be added/changed as appropriate More are brought online during the busy season (summer) Standard delivery 3-5 days from order placement. 6 Five management zones based on relative crop vigor.
