Brazil色视频下载檚 Mato Grosso region is that nation色视频下载檚 leading producer of livestock and grains. It is also a region of extensive land cover change.
Brooke Kubby, a graduate student researcher at the UAF Geophysical Institute, has been researching how time series data from synthetic aperture radars can be used to map rapid expansion of agriculture in dynamically changing environments such as Mato Grosso.
色视频下载淩adar is able to penetrate through clouds,色视频下载 she said. 色视频下载淎nd since it色视频下载檚 active remote sensing, it interacts with land surfaces before returning to the sensor.色视频下载
Throughout the growing and harvesting season, agricultural areas experience changes in the moisture content and structure of the crops.
色视频下载淚n places with crops, many times they have clouds because they色视频下载檙e getting lots of rain,色视频下载 she said. 色视频下载淎nd it can just be difficult to see what色视频下载檚 going on sometimes.色视频下载
Kubby used Sentinel-1 satellite data from 2016 through 2020 in her Mato Grosso research and found that time series data can provide timely updates on changes in cropland extent. The research, she believes, shows the potential to supplement existing crop mapping techniques elsewhere on the globe.
