In situ Data

The points in red in Figure 1 are plots selected for yield prediction and forecasting.  Parcels in yellow are field surveys conducted in October 2015.

Field surveys were conducted on agricultural plots in October 2015. Approximately 900 GPS waypoints were collected to identify crop types following the recommendations of the “JECAM Guidelines for Field Data Collection_v1 0”. Parcels for cropland/crop types identification (in yellow) were manually digitized into polygons (surface data) using the VHSR Pleiades mosaic. Points for yield prediction (in red) will also concur to the validation of the classification products. With few exceptions, almost all points were identified transecting along roads and tracks at the end of the rainy season and using a GPS tablet with Pleiades/SPOT7 base maps.

Plans for Next Growing Season

Next growing season, we will maintain basically the same approach; however, the approach will be further investigated.

The EO data to be acquired will change as follows:

We will continue programming Pleiades images on the area. The vesting period will be the same.
We plan to renew the order for SPOT 6-7 data (one image in the dry season and one at the end of the rainy season).
We hope that this site will be selected for the acquisition of images from the VENUS mission (spatial resolution : 5m / temporal repetitiveness 2 days)
We will rely again on Landsat-8 images, and add Sentinel-2 multi-spectral images to the dataset in 2016 (including L3A products from the “Sentinel-2 for Agriculture” platform).
We expect to obtain further improvement through the use of SAR data for the generation of 2015 crop type maps. We will renew the acquisition of radar data.

We also hope to renew field surveys: this will depend on the security conditions for the organization of the missions.
