Satellite Analysis & Monitoring for Pastures

Eden PA uses the world's highest resolution commercial satellite data to provide detailed and accurate pasture analysis and monitoring services, based on NDVI and/or other spectral indices.

Acquisition, processing and analysis of the world’s highest resolution commercial satellite data to evaluate and monitor pastures.

The best management decisions for pastures are based on longterm performance trends, but the final outcome for each generation of your livestock can be greatly improved if appropriate decisions are made in a timely manner. To get a complete picture of how different parts of your paddocks are performing both in-season and year to year, you need to be able to take measurements from your pasture without destroying it in the process.

Satellite analysis can provide a wealth of information about a pasture that you simply can’t see from the ground. By analysing the wavelengths outside the visible spectrum – the red-edge, near-infrared and shortwave infrared bands – it’s possible to estimate and map variables such as feed on offer (FOO), pasture growth rate (PGR) and many other specific characteristics within a paddock. This leads to much more well-informed decision-making when it comes to feed budgeting and grazing rotation planning. By reviewing imagery for past seasons with similar climatic conditions, combined with records of grazing patterns, it’s also possible to make predictions about pasture growth rates up to six months ahead of time.

Poorly performing or over-grazed areas within paddocks can be detected through once-off satellite analysis long before the problem becomes visible from ground level, and corrective management actions can be trialled and evaluated on the fly using satellite monitoring.

Using data captured by the world’s highest resolution commercial satellites, Eden PA can provide the most detailed satellite pasture analysis services available on the market. With ground resolutions as sharp as 31cm per pixel, right through to broad-scale analysis at 30m per pixel, there are options available for all farms and budgets. While drones can capture imagery at higher resolutions than 31cm, imagery acquired using drones is typically much more expensive and much less accurate compared to Eden PA’s satellite analysis services.

Eden PA’s satellite analysis services are more than just imagery – the process involves radiometrically correcting the imagery to compensate for atmospheric effects and other interference, processing to the data to estimate feed on offer (FOO) and pasture growth rates (PGR), fine-tuning of colour coding in order to display the full extent of variability across the target area, and production of high quality digital maps. Eden PA’s satellite data processing workflow ensures you receive high quality, accurate and reliable analysis which you can put to use immediately. Raw imagery suitable for third-party processing using appropriate software can also be supplied.

Eden PA can provide satellite analysis and monitoring services to assist with the following pasture management applications:

  • Detailed and up-to-date visible spectrum (i.e. RGB) mapping of farm property and infrastructure;
  • Estimation and mapping of feed on offer (FOO) and pasture growth rates (PGR);
  • Analysis of biomass, vigour and stress;
  • Estimation of chlorophyll concentrations and photosynthetic rates;
  • Estimation of foliage cover (i.e. Leaf Area Index);
  • Estimation of soil moisture and detection of waterlogged areas;
  • Detection and assessment of damage due to pests or diseases;
  • Measurement and valuation of losses caused by spray drift, bushfire or floods.

Eden PA’s satellite analysis services are currently available in six different resolutions – 30m, 10m, 1.84m, 1.24m, 46cm and 31cm. The resolution refers to the size of each pixel in metres on the ground. In a 30m resolution image, each pixel covers a ground surface area of 30m x 30m = 900m2 in total, while each pixel in a 10m resolution image covers an area of 10m x 10m = 100m2, and in turn each pixel in a 31cm resolution image covers an area of 31cm x 31cm = 961cm2. Therefore a 10m resolution image will contain nine times the amount of detail and precision as a 30m resolution image, and a 31cm resolution image will contain over 1,000 times the level of detail as a 10m resolution image.

Delivery Options

These satellite analysis services are available in three delivery modes:

  • Once-off analysis: This is a good option if you just want a quick analysis (e.g. a feed on offer map) of a specific area at a specific point in time, or if you’ve had imagery captured previously and want an updated analysis to check against your existing/historical imagery;
  • Longterm analysis: This comprises a separate analysis of 3 images (normally captured at the same time of year over a 3-year period), plus a combined analysis showing the average of the specified reading/measurement across all three images;
  • Ongoing monitoring program: Updates provided either at a predetermined frequency or on an ad-hoc basis, according to customer requirements. Each update comprises two images – one up-to-date analysis of the target area, plus a second image which shows areas in which the specified reading/measurement has increased (shown in green) or decreased (shown in red) within the target area.
