The Kansas Applied Remote Sensing Program (KARS) uses satellite data to produce a weekly map series called the GreenReport®, which illustrates current and relative vegetation conditions and trends for the conterminous U.S. Since 2002, KARS has also used these satellite data to forecast district, state, and national level crop yields for eight major crops in the U.S.
The advantage of displaying satellite-based vegetation information in map form is that locally specific growing conditions can be ascertained. The GreenReport® combines current satellite data with historic data to present a more complete picture of vegetation condition and progress. The data archive underlying the GreenReport extends back to 1989. The raw data used for the GreenReport® are produced and distributed by the USGS EROS Data Center.
GreenReport® maps (which are updated on a weekly basis throughout the growing season) present five different views of current vegetative condition:
• current greenness (NDVI)
• greenness change from the previous week
• difference from the same week last year
• difference from the long-term average greenness for the week
• current vegetation condition relative to normal
The vegetation condition map illustrates vegetation health and levels of plant stress, and is based on current and historic vegetation greenness and surface temperature data collected by satellites.
Since 2008, the GreenReport® maps have been featured in Planalytics’ Insight newsletters. Planalytics is a commercial partner of KARS through Lawrence-based TerraMetrics Agriculture, Inc. Planalytics also features KARS crop yield forecasts in their Life Sciences product line, in the form of biweekly, pre-harvest crop reports that integrate satellite and weather intelligence to assess the current outlook for U.S. winter wheat, corn, and soybean crops.
