Although the definition of fraction of canopy cover known as FCOVER is very simple (fraction of ground area covered by vegetation canopy), it is important to clearly understand and specify the ground measurement methods for canopy cover in order to avoid discrepancies in terms of definitions of remotely sensed FCOVER (varying from 0 and 1) and objectives of the field data survey. The field survey methods for canopy cover are done to establish percentage canopy cover of member species, however the total canopy cover can also be estimated from these measurements.

GLAMASome mobile apps have been developed to measure total canopy cover fraction based on photographs captured by camera looking vertically upward or downward. These apps calculate canopy cover by segmenting photographs and separating vegetated pixels against dark soil or sky background. Some examples of apps – GLAMA, Canopy Cover Free, CanopyApp, Canopeo, HabitApp.
