# Field boundaries for Cambodia and Vietnam (AI4SmallFarms)

The large-scale data set consists of 439,001 field polygons divided into 62 tiles of approximately 5×5 km distributed across Vietnam and Cambodia, covering a range of fields and diverse landscape types.
The field polygons have been meticulously digitized from satellite images, following a rigorous multi-step quality control process and topological consistency checks.
It has been converted to a fiboa GeoParquet file.
