In the assessment of time since forest disturbance, we define disturbance as the drop of TCC from =10% to 0%. Use following code or the link here.

Rotation of the forest is defined as the number of forest disturbance events for the year range, with disturbance defined as a drop of Tree Canopy Cover from >=10% to 0%, or the loss from 1 to 0.
The pseudo-code for the rotation map can be written as:
We travel time for 3 years and … CONTINUE READING
With the Google Earth Engine, it’s very easy to calculate the amplitude of any time-series datasets. The amplitude in wave physics is defined as the distance between the high and the low peak as shown in the picture below. Similarly, for any raster datasets for a time series, the amplitude is the difference of the … CONTINUE READING
The primary forest can be mapped in a number of ways. One of them is described here, where the base year 2000 map for the primary forest is used in relation with the forest definitions on tree canopy cover (tcc) and tree canopy height (tch) to calculate the primary forest in each year. Turns … CONTINUE READING
GLAD at UMD provides the primary forest for 2000 which is the base map for most of their analysis. This primary forest consists of natural long-lived forest extent. The mapping and definition for the primary forest are based on the methodology as described in the paper for humid tropical forests and modified to include dry … CONTINUE READING
