Special Issue Information

Dear Colleagues,

The group on the Earth Observations Global Agricultural Monitoring (GEOGLAM) Flagship Initiative has made significant contributions to increase market transparency and support food security, based on Earth observations (EO), as well as various other data sources. At its inception, most satellite data were still required on a tasked basis and distributed on a fee-based model. However, as the European Copernicus program has recently launched a variety of resource, environmental, and meteorological satellites with full, free, and open data policies, we are now entering a world of data plenty where the data volume of EO data, accessible and suitable for agricultural monitoring, has expanded significantly. Consequently, processing and analyzing of high volume remote sensing data at the national/global scales has become a major challenge, both in terms of data storage and computing capacity, and GEOGLAM must address how to manage, process, and maximize the value of these significant EO investments.

The GEOGLAM 2018 Annual Meeting, focusing on topic of GEOGLAM Cloud Infrastructure and Knowledge Management, will bring together scientists and professionals from different countries to discuss how the cutting-edge technology of cloud infrastructure, big Earth data, and knowledge management can benefit and leverage GEOGLAM.

We are thus inviting authors and research teams to publish their recent work in the area of agricultural monitoring with cloud computing, and we are especially excited to receive contributions that report on good examples of methods that work. We invite papers on the following non-exhaustive list of topics:

  • Cropland or crop type mapping at medium to high resolution.
  • Approaches for automated crop field boundary detection
  • Cloud based method or system in support of agricultural monitoring
  • Ready to use data for agricultural monitoring
  • Novel time series analytics, especially in the domains of cropland, crop type, crop calendar, crop successive, cropland use intensity, crop condition monitoring methods

The distribution of corn cultivation areas is crucial for ensuring food security, eradicating hunger, adjusting crop structures, and managing water resources. The emergence of high-resolution images, such as Sentinel-1 and Sentinel-2, enables the identification of corn at the field scale, and these images can be applied on a large scale with the support of cloud computing technology. Hebei Province is the major production area of corn in China, and faces serious groundwater overexploitation due to irrigation. Corn was mapped using multitemporal synthetic aperture radar (SAR) and optical images in the Google Earth Engine (GEE) cloud platform. A total of 1712 scenes of Sentinel-2 data and 206 scenes of Sentinel-1 data acquired from June to October 2017 were processed to composite image metrics as input to a random forest (RF) classifier. To avoid speckle noise in the classification results, the pixel-based classification result was integrated with the object segmentation boundary completed in eCognition software to generate an object-based corn map according to crop intensity. The results indicated that the approach using multitemporal SAR and optical images in the GEE cloud platform is reliable for corn mapping. The corn map had a high F1-Score of 90.08% and overall accuracy of 89.89% according to the test dataset, which was not involved in model training. The corn area estimated from optical and SAR images was well correlated with the census data, with an R2 = 0.91 and a root mean square error (RMSE) of 470.90 km2. The results of the corn map are expected to provide detailed information for optimizing crop structure and water management, which are critical issues in this region. Full article
