Satellite Analysis & Monitoring for Broadacre Crops


Eden PA uses the world's highest resolution commercial satellite data to provide detailed and accurate broadacre crop 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 broadacre crops.

The best management decisions for a crop are based on longterm performance trends, but the final outcome of a single season can be greatly improved if appropriate mid-season 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 crop without destroying it in the process.

Satellite analysis can provide a wealth of information about a crop 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 chlorophyll content, leaf moisture and many other specific characteristics across a paddock. Poorly performing 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 crop 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 crops of all types – from broadacre crops and pastures through to orchards and vineyards. 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 create colour-coded analysis maps using a range of spectral indices commonly used in vegetation analysis, 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.

Spectral index maps can provide very accurate indications of various aspects of pasture growth, nutrition and stress, and can indicate problems which are not detectable using visual assessment. Unlike yield monitor data, remote measurements of crop vigour can also be obtained mid-season, allowing acute problems to be detected and addressed while there is still time. When combined with ground truth data (e.g. soil or plant tissue tests), these maps can be used to identify the specific factors limiting growth rates across a paddock, allowing for the creation of management zones and prescription maps for precise application of fertilisers and other inputs.

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

  • Detailed and up-to-date visible spectrum (i.e. RGB) mapping of farm property and infrastructure;
  • Analysis of biomass, crop vigour and crop stress;
  • Estimation of chlorophyll concentrations and photosynthetic rates;
  • Estimation of foliage cover (i.e. Leaf Area Index);
  • Forecasting crop growth and yields;
  • Estimation of soil moisture and detection of waterlogged areas;
  • Detection and assessment of crop damage due to pests or diseases;
  • Measurement and valuation of crop 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 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.
