Weather and Earth remote sensing (ERS) data

What kind of weather data is accessible in the system?

For each field, you can view current meteorological conditions (temperature and relative humidity, precipitation, cloud cover, atmospheric pressure, dew point), the 14-day weather forecast, and historical weather data:

• Weather history in the field for the entire season;

• Total of active temperatures;

• Cumulative rainfall.

What do you mean by “field-by-field forecast?”

Our weather-data provider uses a unique algorithm for computing and forecasting weather conditions for each of your fields, taking the center of the field as the reference point. Our ability to use data from local weather stations and precision calculations makes it possible to identify slight differences in current weather conditions and forecasts for your fields, even in the case of small farms. In order to get even more precise forecasts, you can install a weather station from one of our partners at your farm and the data it collects will be automatically included in our calculation algorithm.

How is the weather data sourced?

We use climactic data and weather forecasts from the provider

Having your own weather station connected to the ExactFarming system will make it easier to provide you with a more precise and timely forecast – as well as to warn you of dangerous weather conditions.

What do you mean by field “vegetation?”

In order to determine the vegetation in your fields, ExactFarming uses a Normalized Difference Vegetation Index (NDVI), which makes it possible to calculate the current status of plant cover based on a differentiation map. You can use the differentiation map to look at each individual field, or to look at a group of fields (such as all fields planted with the same crop). The map also features a graphic of vegetation changes – both for the current season, as well as in the form of a multiyear history. Comparing and contrasting the vegetation-change graphic and weather history makes it possible to draw fact-based conclusions about the state of your fields and causes for any deterioration/improvement in vegetation.

How is the field-vegetation data sourced? How up-to-date is it?

Our vegetation-determination services are built on low- and medium-resolution imagery – 250 m and 30 m. Frequency of data updating – once every 8 days.

Next year, we’ll be glad to offer you an additional paid service that you can activate as you please – daily vegetation data with medium- and high-resolution imagery.
