IowaView staff have released the Cover Crop ID Toolbox and Handbook. This toolbox allows users to quickly identify possible cover crop fields using three Sentinel-2 images from the fall, early spring, and late spring downloaded from the Earth Explorer website based on field boundaries supplied by the user. On the project webpage you can download the toolbox which works with both ArcMap or ArcGIS Pro as well as the Cover Crop ID Toolbox Handbook that provides additional details about each step of the tool.
Today, Mike Daniels from the University of Arkansas will be presenting about how the Arkansas Discovery Farm is reducing nutrient loss, defining and building soil health, improving irrigation efficiency and edge-of-field monitoring of runoff. His statewide Extension efforts encourage agricultural producers to adopt conservation practices to protect natural resources and improve agricultural sustainability.
Today we are celebrating remote sensing, the study of the earth using secondary observations from instruments such as planes, kites, drones, satellites as an exciting and powerful educational tool to help us show changes over time.
This year the AmericaView/NASA team has put together a fun and beautiful educational poster!
This week marks 40 years since the Mount St. Helens eruption. The image above is from the USGS Earthshots trading card series. The images are displayed in color infrared which is useful for showing living vegetation in red. The mountains surrounding Mount St. Helens are primarily forest. Notice the extreme change in the landscape from the 1973 image to the post eruption image in 1983. The damage was extensive and ash covered much of the surrounding forest land.
