Poland – Wielkopolska

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):     (Click here to enter text.)

What is the current project phase?     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

LAI

  • Crop Type(s): Forest
  • 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: two / three times per month

Spectral Reflectance

  • Crop Type(s): Forest
  • 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: depends on sun conditions

APAR

  • Crop Type(s): Forest
  • Collection Protocol:

    AccuPAR LP-80 instrument by Decagon Devices

  • Frequency: twice/three times a month

Soil Moisture

  • Crop Type(s): Forest
  • Collection Protocol:

    TRIME-PICO64 sensor with internal TDR-electronics by IMKO

  • Frequency: twice/three times a month

Radiance temperature

  • Crop Type(s): Forest
  • Collection Protocol:

    The handheld infrared thermometer EVEREST AGRI-THERM II

  • Frequency: twice/three times a month
