About the data
The airborne gamma radiometrics data has been surveyed by various companies on line spacings up to 500m and processed to an 80m grid, which we then resample at 10m. This data has a 75% correlation with ground-based measurements (see below).
The satellite biomass (NDVI) data consists of one image per year, captured at peak spring biomass. Data is resampled from 25m pixels down to 10m, split into paddocks and named according to crop type.
We will enter your existing georeferenced soil data and paddock boundaries into the Visionag Gateway software, provide a basic level of data analysis, create management zones and support you in getting prescriptions running in your tractor.
This package is only available for a minimum area of 1000ha. Call us for a quote or contact us for more details.
 Depending on availability of data. Additional years of yield data processed at a rate of 72c/ha. Additional fees for header matching. Contact us for a quote on soil sampling and analysis
