PiMapping® uses remote sensing data as input to analyze it with the SEBAL calculation- and interpretation model. Wim Bastiaanssen (founder of WaterWatch) is the founding father of de SEBAL model. The intellectual property belongs to eLEAF.
SEBAL is the only model in the world that is able to define a multiplicity of quantified crop parameters out of a large number of bands of the radiation spectrum (you will find an extensive description of SEBAL here). The SEBAL model makes it possible to measure and calculate all vegetated surfaces throughout the world just from one place, the eLEAF office.
PiMapping® is short for Pixel Intelligence Mapping. As input, the PiMapping® Technology uses different types of data sources. Data sources contain different types of information providers. The most common used are satellite imagery, weather information (e.g. wind, temperature, humidity) and precipitation data. This information is being processed by the PiMapping® Technology which consists of different tools (like SEBAL, ETLook and METEOLook). This technology is able to make a pixel intelligent, so it will become a ‘smart pixel’, which provides information about cropped surfaces. These smart pixels enable application developers to make applications that are very useful to different end users, e.g. the agricultural sector.
eLEAF is capable to equip every smart pixel of imagery, which are coming in different resolutions, with information about growth, moisture, minerals and yield. It is possible to deliver data per pixel every week. For example about the following data components:
- Biomass production (kg/ha)
- CO2-intake (kg/ha)
- Leaf Area Surface (m2)
- Actual evapotranspiration (mm/week)
- Nitrogen (kg/ha)
- Yield of different crops (kg/ha)
This data will come in absolute, quantitative numbers and this information enables sustainable and efficient use of water, resources and chemicals.
