MULTISPECTRAL IMAGING & MAPPING

 

 

ONE THING ABOUT PRECISION AGRICULTURE IS THAT
YOU CAN BE WRONG WITH A GREAT DEAL OF PRECISION

 


At Skygate, we understand that reliable, accurate and consistent data is essential for making crop management decisions, and with over 15 years experience in multispectral imaging, this is our speciality.
Using post-flight photogrammetry software and state-of-the-art drone mounted sensors, we are able to deliver fast, accurate and reliable crop health NIR data, identifying crop stresses before they become visible, with Weed Maps & Plant Counts,  and 3D RGB orthomosaic imaging for soil moisture content and irrigation planning etc..
We use the best equipment on the market and deliver the most accurate and precise data multispectral technology can offer.
We care about your crops and are committed to providing software training support, and helping you understand your data with a continuous improvement and support program.
Skygate is the only Transport Canada approved ‘Advanced Drone Flight Reviewer & Advanced Operations Instructor’ in PEI, and with over 15 years experience operating Remotely Piloted systems, we know how to get the absolute best from multispectral image sensing, ensuring you get the best ROI from investing in us.

Just some benefits of remote multispectral crop sensing?

PRE-PLANT, PLANT & EMERGENCE
Evaluate seed, inputs and equipment performance
Predict outcomes sooner and with better accuracy
Improve in-season management decisions
Produce plant population map
Monitor weed density and locations
Accurate zone maps for variable rate planting
IN SEASON PRODUCTION
Improve irrigation management
Analyze crop health at field edge
Identify disease or pest outbreaks ‘before’ they become detrimental
Validate treatment effectiveness
Act weeks before issues are visible to the naked eye
 
LATE SEASON & HARVEST
Determine late season nitrogen needs
Reduce overfertilization, leading to less nitrate pollution
Evaluate harvest readiness
Identify harvest order
Apply inputs with precision
Plan irrigation scheduling to avoid leaching of N
OFF SEASON
Create land levelling and drainage plans and practices

Agricultural Survey & Mapping FAQ's

If you have a drone registered with Transport Canada, and have passed the RPAS Basic operators exam, you can fly a drone over a field (providing it is in class G airspace and more than 5.5Km from an airport). You will also need to keep the drone less than 500 Mtrs from you, and follow the TC CARS part IX rules and regulations, maintaining RPAS maintenance Logs, Site Surveys and Check Lists etc., and have all the various emergency procedures and communications in place to legally fly a drone. If you want to operate beyond 500 Mtrs (BVLOS), or in ‘controlled’ airspace, you would also need to become an ‘Advanced’ RPAS Operator and apply for a SFOC (Special Flight Operations Certificate) for BVLOS flight operations.

Using a small RPAS with a single sensor ‘may’ get you some useful data for ‘some’ crops, during ‘some’ of their growth cycle (and only with certain weather and lighting conditions). However, knowing and understanding when the data is valid or misleading (and what type of sensor to use) is the key to successful crop management and precision agriculture.

Flying drones and collecting crop data (all adjusted and calibrated for your crops in your fields, and for a specific growth cycle), is our speciality. SKYGATE is committed to delivering the best data for your crops in the most cost effective way for your ROI. We want to help you get the most out of investing in this technology, and  see the benefits of precision agriculture.

A ‘Vegetation Index’ is a measurement of plant health that uses the ‘Near Infrared’ and the ‘Visible Light’ spectrums to detect a plants health and stresses, long before it can be seen by the naked eye (by which time irrecoverable damage to the plant may have occurred!). Ground moisture, field irrigation, weed counts, crop disease, Nitrogen levels and soil conditions can all be quickly analyzed with professionally collected vegetation indices data. There are many indices that are used in plant analysis, NDVI, NDRE, GNDVI, OSAVI, GVI, PVI etc., and understanding what spectral measurements are required for a particular crop, at a specific time of the growth cycle (and in what light conditions and altitudes), is essential for the collection of accurate and reliable data for the farmer to make the right pro-active decisions for their crop management.

Data is compatible with existing agriculture data analytic tools including the John Deere Operations Center, APEX, SST, SMS, FarmWorks, Encirca, FieldView + more

Ground control points are large marked targets on the ground, spaced strategically throughout the area of interest, referenced to RTK GPS coordinates. The ground control points and their coordinates are then used to help drone mapping software accurately position the map in relation to the real world around it.

NDVI/NDRE data should ideally be collected ‘several’ times throughout the growing season, in order to fully understand the growth cycle and stresses your crops experience. However, if you feel your crops and field irrigation is generally good, then we recommend a minimum of four datasets over the course of the growth cycle. This would give you some overall data to reference in the future, and highlight some areas of concern that you may wish to follow up with ground truthing.
