Abstract

Terrestrial ground truthing of land use has been carried out between 2016 and 2019. Land cover types classification is identical to mapping of land use types. For project information see www.la-foret.org.

Data Quality

Field teams were composed by two to five researchers familiar with the locally prevailing forest and land use types, together with local guides familiar with a particular landscape. They spent approximately six weeks in each landscape, following a standardized field protocol based on existing good practice guidelines. A stratified sampling approach was applied to capture the main forest and land cover/land use types in each landscape. These strata were identified by the expert teams on the ground, through related activities within the larger LaForeT project (e.g. scoping visits, key informant interviews, community workshops, participatory mapping exercises, household interviews, forest inventories). The delineation of relevant strata and the design of the field sampling campaign built on visual interpretation of existing satellite images (Google Earth imagery) or auxiliary maps. The teams covered every pertinent class with a representative number of GCPs, spatially distributed across each landscape. Cross calibration on land use classification was regulary carried out in the field and campaign leaders were present in all three countries to ensure harmonized asessment.
