JECAM | Joint Experiment for Crop Assessment and Monitoring

Germany - DEMMIN

Project Overview

1. Crop Identification and Acreage Estimation

2. Soil Moisture

3. Crop Biophysical Variables

 

Mapping Resolution:
Varies from within site specific (5-10 m) to regional analysis (100 – 1000m)

Timeliness (with regards to growing season): 
A main priority from March-October

Current Project Phase:
Research


Project Reports


Implementation Plans

1. Crop Identification and Acreage Estimation: Annual

2. Soil Moisture: In the DEMMIN test site there are 45 autonomous operating automated stationary environmental measurement stations with soil moisture probes (up to 1m depth,10cm resolution) and 65 soil moisture gauging stations below agricultural used fields (depths 50cm, 70cm). The measuring interval is 15 minutes.

3. Crop Biophysical Variables: For specific fields: LAI (Sunscan), crop type, crop cover, wet biomass, phenology, and plant density.
