NbS: Determine land cover

This template project uses a Global Land Cover Classification data product to report on land cover types and how they have changed over time. This can be used to give a high-level overview for checking reported forest extent at either a project area or a reference area.

What should I use this template for?

This template should be used to undertake a quick assessment of forest cover and whether this has changed over time.

What data has been used?

The data used in this template is the WRI Dynamic World data product. This is a 10m near-real-time land use and land cover dataset that classifies each pixel into one of nine classes, as well as the % probability of it being one of the other classes.

The dataset is derived from Sentinel-2 data from 2015 to the present, with data updated approximately every 5 days. Only data which has a cloud cover of less than 35% is included in the process to produce the Dynamic World dataset. This means that for some time periods, some pixels may not have any data.

This dataset can give you a good high-level overview of forest extent in your area, and how that has changed over time. However, for verification purposes, the accuracy of this analysis can be both improved and extended back to 1982 using additional data sources such as Landsat.

What do the outputs show me?

Map Outputs

This template project has only one map output layer. This shows the land cover classification for Cambodia for 2022. The legend on the left-hand side tells us that the colour scheme relates to the land cover classes.

Dashboard Outputs

If we look at the dashboard tab, you will see that we have one chart and two tables. The chart shows the area of each land cover class for the whole of Cambodia. One of the tables reports the same information in tabular format. This chart can be downloaded as an image using the download button at the bottom-left of the chart. You will have the choice of downloading it as an image, or the underlying data as a CSV spreadsheet. This is true of all charts created with Earth Blox.

The table called Projects Land Cover (ha) shows the area of each land cover class within each project site. This data can also be downloaded as a CSV spreadsheet using the download button at the bottom-left of the table. This is true of all tables created with Earth Blox.
