Estimating urban lawn cover in space and time: Case studies

Journal :

Comment :
They review the existing literature of lawn cover in cities and the different methodologies used for cover estimation. They found both pros and cons with NDVI and LiDAR data as well as manually interpreted aerial photos. During 50 years lawn area almost doubled in relative cover and 56% of them were continuously managed. Since lawns constitute large parts of the urban greenery and are costly to manage it is highly relevant to consider their social, ecological and cultural value compared to alternatives, e.g., meadows with less intensive management.
