JECAM | Joint Experiment for Crop Assessment and Monitoring

Poland - Wielkopolska

Project Overview

Goals of the site in terms of:

Mapping Resolution: 10 m for the field estimates        

Timeliness (with regards to growing season): Growing season (April-October)          

Operational implementation plans (if any):     n/a       

What is the current project phase?

            ☐ Research                 ☐ Operational Pilot                ☒ Operational  

Please describe how and reasons why the site is operational.

 

1. Crop identification and acreage estimation: Annual
2. Residue and Tillage mapping: N/A
3. Soil moisture: Soil moisture has been measurement by TRIME Field Measurement Devices three times a month.
4. Crop biophysical variables: LAI, fAPAR. Indices (e.g. NDVI) are computed based on field measured hyperspectral reflectance data collected by using Field Spectro radiometer (ASD FieldSpec4 Hi-Res).
5. Other: The height and have been recorded. Also photos for each crops have been taken. All data have been stored in the prepared data base.

In Situ Observations

  1. Parameter: Radiance temperature
    Data Collection Protocol:

    The handheld infrared thermometer EVEREST AGRI-THERM II

    Frequency: twice/three times a month
  2. Parameter: LAI
    Data Collection Protocol:

    LAI measurements on the ground (LAI(G)) have been made on the dates of satellite pass using the Plant Canopy Analyzer (Model: LAI – 2200C) of Licor Biosciences, USA. At each measurement location, one above canopy and four below canopy readings (repetition twice) have been recorded to compute a single LAI value.

    From each measurement location, three LAI value have been recorded. Above and below canopy measurements have been made with a ‘‘fisheye’’ optical sensor with 148º angle of view. An azimuth mask of 270º view cap has been used on LAI-2200C sensor during data collection to block the bright sky for eliminating the shadowing effect of instrument operator.

    Frequency: twice/three times a month
  3. Parameter: Spectral Reflectance
    Data Collection Protocol:

    The hyperspectral spectroradiometer “FieldSpec4 Hi-Res” by ASD (Analytical Spectral Devices) has been used to collect canopy reflectance data. The FieldSpec4 Hi-Res spectroradiometer has a spectral range of 350 nm to 2500 nm with a field view of 25 degrees.

    The measurements have been taken by holding the spectroradiometer at a height of 20-30 centimeters above the canopy (depends on calibration process) with the viewing angle of 25 degrees. From each measurement location, 10-15 canopy reflectance data have been collected.

    Frequency: It depends on sun conditions
  4. Parameter: APAR
    Data Collection Protocol:

    AccuPAR LP-80 instrument by Decagon Devices

    Frequency: twice/three times a month
  5. Parameter: Soil Moisture
    Data Collection Protocol:

    TRIME-PICO64 sensor with internal TDR-electronics by IMKO

    Frequency: twice/three times a month
