Land-Cover Mapping of Agricultural Areas Using Machine Learning in Google Earth Engine

Abstract: Land-cover mapping is critically needed in land-use planning and policy making. Compared to other techniques, Google Earth Engine (GEE) offers a free cloud of satellite information and high computation capabilities. In this context, this article examines machine learning with GEE for land-cover mapping. For this purpose, a five-phase procedure is applied: (1) imagery selection and pre-processing, (2) selection of the classes and training samples, (3) classification process, (4) post-classification, and (5) val… Show more

“…The average annual temperature and total precipitation during the period 1961-1990 are 17.5 °C and 1100 mm, respectively (25) . Between 1990 and 2018, a remarkable change in land use was registered in the San Salvador basin (Table 1 and Figure 2) (20) : cropland increased from 953 to 1,495 km 2 (57%), grassland decreased from 1,358 to 749 km 2 (45%), and production forest increased from 12 to 78 km 2 (570%). Land management also changed: in 1990, cropping with grazing combined with livestock and till practices prevailed, while in 2018, continuous cropping, no-till, and transgenic crops prevailed (26) .…”

“…This study considered the San Salvador watershed, an agricultural basin in Uruguay. This basin is representative of the agricultural expansion process of the country (20) and now has the potential to intensify its production through supplementary irrigation (21)(22) . The irrigation development changes land use and management and affects the water quality and quantity of the San Salvador River.…”

“…The San Salvador River basin belongs to a major agricultural area in the Southwest region of Uruguay characterised by a smooth hilled landscape under a humid subtropical climate and with an average precipitation of 1100 mm/year. Since 1990, but mainly after the 2000s, this basin was a subject to an intensification process of fast‐growing crop areas with soybeans, corn, wheat and barley as the main crops, which generally substituted native grasslands (Hastings et al., 2020). Despite showing a high inter‐annual rainfall variability, most of its area is under rain‐fed crop production.…”

“…To show the appropriateness of the approach in tackling the two main issues around water (quantity and quality), and their interaction with the economic activities within the basin, we calibrate and run the model and the scenarios on a particular basin of the temperate region of South America. This basin of the San Salvador River in Uruguay is characterised by the expansion of agriculture along both the extensive and intensive margins, the growth of urban areas and industrial development, and as a result, an increasing pressure on water resources (Hastings et al., 2020; MVOTMA, 2017). The scenarios implemented replicate two of the main challenges in the basin.…”

“…Uruguay has a humid subtropical climate (Cfa, according to the Köppen climate classification) with a mean temperature in the warmest month equal to 22 • C or higher [18]. The study area is characterized by total annual precipitation that varies between 1000 mm and 1500 mm and a temperature that can vary between 3 • C and 30 • C [19].…”
