Mapping Smallholder and Large-scale Cropland Dynamics with a Flexible Classification System and Pixel-based Composites in an Emerging Frontier of Mozambique

(1) Pixel-based compositing impacts classification results. (2) Median compositing performed best for disaggregating cropland by field size. (3) Textural features facilitate the separation of small- and large-scale cropland. (4) Mapping cropland scale dynamics can improve understanding of land and food systems.

The Extent of Forest in Dryland Biomes

Dryland biomes cover two-fifths of Earth’s land surface, but their forest area is poorly known. Here, we report an estimate of global forest extent in dryland biomes, based on analyzing more than 210,000 0.5-hectare sample plots through a photo-interpretation approach using large databases of satellite imagery at (i) very high spatial resolution and (ii) very high temporal resolution, using Collect Earth software.

Collect Earth: Land Use and Land Cover Assessment through Augmented Visual Interpretation

Collect Earth is a free and open source software for land monitoring developed by the Food and Agriculture Organization of the United Nations (FAO). In this study, we provide a full overview of Collect Earth’s structure and functionality, and we present the methodology used to undertake land monitoring through augmented visual interpretation using Papua New Guinea as a case study.
