Early-season use cases: Water management

 

TerrAvion high-resolution subscription imagery enables use cases during the whole growing

TerrAvion aerial imagery with its wide variety of bands, including a high-resolution Pansharpened Thermal and Synthetic Color, provides many use cases during the whole growing season. High-resolution aerial subscription imagery allows you to use data for situations that you might not have foreseen, that other imagery programs can not support due to missing bands and lacking detail, or that misses the data you need due to timing. The advantage of having a whole season of imagery is that you can monitor and find changes during the entire season.

With many use cases for image data during the whole season, below is an overview of some that focus on early-season water management.

Early-season water management: Planting

The dark colors in this field have a much lower temperature indicating that the moisture content is very high. If not addressed before planting, this field will not provide good yield on every acre.
 

Many regions in the USA experience flooding from large amounts of rain, melting snow, or overflowing rivers causing waterlogged soil. TerrAvion customers use early-season thermal imagery to identify flooded and over-saturated areas in their fields. While standing water may be easy to locate, a thermal image band can help identify areas affected by flooding that might not be immediately evident on the ground level. After standing water has settled out of sight, into the soil, thermal images will still be able to tell what areas hold more water in the land than others. Armed with this information, the TerrAvion OverView platform can build management zone maps based on the thermal band that allows for planting seeds away from over-saturated areas and place them in areas where they are more prone to success.

Early-season water management: Nutrient leaching

Over-saturated areas are also prone to nutrient leaching. While an immediate fix can be done, this information can also be useful later in the season to learn why vigor in some areas of the field is lower than expected.

The TerrAvion thermal band can be used to create variable rate maps that allow for efficient variable rate nutrient replenishment applications. Dosing fertilizer only where you need it limits costs and prevent polluting water ways.

Early-season water management: Tiling

If over-saturated areas warrant drainage or tiling, high-resolution imagery gives growers a precise map that pinpoints the location and severity of soil saturation issues, as is shown in the example below.

TerrAvion vs. Satellite: Flooding

If you have an image program that does not offer thermal imagery, you might miss out on getting a good start of the growing season. In the images above, the TerrAvion Thermal on the left clearly illustrates the flooded areas in this field where the darker colors represent a lower temperature due to higher moisture content. None of the available satellite images from the same date (pictured to the right, no thermal as satellite does not provide a thermal band) provide any information on flooding in this field. This example alone shows just how different imagery programs can be.
