The smartphone app “Drought Information Supported by Citizen Scientists” (DISCS) was created by researchers at NASA’s Marshall Space Flight Center to facilitate the sharing and delivery of hydrologic and agricultural information from citizen scientists to the scientific community and partners involved in the monitoring of drought conditions. Users, as Citizen Scientists, are encouraged to contribute photos of local crop conditions along with information about crop type, crop health, soil moisture conditions, and other notes about drought impacts. In exchange, users of the app can observe their reports alongside reports of other Citizen Scientists, and view their information in the context of drought information from the U.S. Drought Monitor, recent rainfall data from NOAA, soil moisture information from ground sensors or through NASA modeling approaches, and view information about vegetation health and stress as observed from NASA’s constellation of satellites.

Great for gardeners & farmers

This is a simple App that lets you know where you stand with rainfall and drought. Menus are easy to navigate (though like many apps, if you have big calloused fingers it’s hard to be precise with checking boxes)
If i could ask for one thing it would be bigger check boxes (whatever they are called) to select. And maybe a “close menu “ button? I quickly figured out that touching the map closed the menu.

Menu in the way

There is no way to close menu which covers the map rendering app useless
