GLOBE Land Cover: Getting Started
Open the GLOBE Observer App and select Land Cover.
Verify the date, time and your location.
Observer a 100 meter x 100 meter area. This is about the length of a soccer field.
Report the surface conditions.
Capture Your Surroundings: Tilt your phone to capture 50 meters of land in each direction.
Submit photos now or classify the land cover.
Classify the Land Cover: Determine what type of land cover is in each photo.
Tap on the “i” icon to see a description of the land cover types.
Tap the photo to see a large version of it.
Estimate how much of each type you see in the photo.
Percentages may total over 100% especially if trees are growing over another land cover type, like grass or shrubs.
Need help with your observations? Select the question-mark on the bottom right corner.
When you’re done, send your observations to GLOBE.
Compare with Satellite Data: Select “My Map” to compare your observations to satellite data.
If your observation is different from NASA’s, tap “Report a Difference.”
Return to the same location to record changes over time and contribute to a global database of observations.
