District-wise distribution pattern of five major weeds in prominent crops of India was developed and published as ‘Weed Atlas’ in two volumes by the ICAR-Directorate of Weed Research, Jabalpur in 2008. The weed maps highlighting the weed distribution in major crops under varying agro-ecological conditions of the country are useful in prioritizing weed management research in the country. Graphically displayed data can have a profound effect on the conclusions drawn from a data set. Different types of weed maps were prepared through entered data. Maps were prepared for state- and crop-wise for different weed intensity level (i.e. very high, high, moderate, low and very low). This is a user-friendly web-based Weed Map Thumbnail module. User can select the requisite state and crop to retrieve the weed infestation level.
