In tropical/subtropical regions, the favorable climate associated with the use of agricultural technologies, such as no-tillage, minimum cultivation, irrigation, early varieties, desiccants, flowering inducing and crop rotation, makes agriculture highly dynamic. In this paper, we present the Campo Verde agricultural database. The purpose of creating and sharing these data is to foster advancement of remote sensing technology in areas of tropical agriculture, primarily the development and testing of methods for crop recognition and agricultural mapping. Campo Verde is a municipality of Mato Grosso State, localized in the Cerrado (Brazilian Savanna) biome, in central west Brazil. Soybean, maize and cotton are the primary crops cultivated in this region. Double cropping systems (e.g., soybean-maize) are widely adopted in this area. There is also livestock and forestry production. Our database provides the land use classes for 513 fields by month for one Brazilian crop year (between October 2015 and July 2016). This information was gathered during two field campaigns in Campo Verde (December 2015 and May 2016) and by visual interpretation of a time-series of Landsat-8/Operational Land Imager (OLI) images using an experienced interpreter. A set of fourteen pre-processed Synthetic Aperture Radar (SAR) Sentinel-1 and fifteen Landsat-8/OLI mosaic images is also made available. It is important to promote the use of radar data for tropical agricultural applications, especially because the use of optical remote sensing in these regions is hindered by the high frequency of cloud cover. To demonstrate the utility of our database, we present the results of an experiment conducted using the Sentinel 1 dataset.
Campo Verde is a municipality of Mato Grosso (MT) State in the central west region of Brazil. This municipality is located in the Cerrado Biome at a latitude of 15°32’48” south and longitude of 55°10’08” west, and it has an area of 4,782.118 km2 with an altitude of 736 meters. The agricultural calendar (Brazilian crop year) stretches from late August to the following July, with two planting periods during the rainy and dry seasons (first and second harvests, respectively). In Campo Verde, soybean is planted in September to December and harvested in January to April. Cotton can be planted from October to January and harvested in April to September. Maize is planted in January to March and harvested in June to September, and second- harvest maize is planted in January to March and harvested in June to September.
To build reference data for the Brazilian crop year 2015/2016, two field campaigns were conducted in Campo Verde between 14th and 18th December 2015 and 9th and 13th May 2016. The first campaign aimed to acquire information about the first harvest (summer crops, rainy season); and the last focused on the crops cultivated during the second harvest (dry season).
In total, 14 land use classes were detected: soybean, maize, cotton, beans, sorghum, NCC–millet, NCC-crotalaria, NCC-brachiaria, NCC-grasses (i.e., identified grasses), pasture, turf grass, eucalyptus, Cerrado and uncultivated soil (i.e., bare soil, soil with crop residues from the previously harvest, soil with weeds).
The database consists in three folders:
- SAR: a set of 14 Sentinel-1 images, co-registered and calibrated.
- LANDSAT: a set of 16 Landsat 8 OLI images
- Reference: an ESRI Shapefile with the classes for each one of the 513 polygons (parcel) in each date.
