Where are PV power plants located in China?

Eventually, we established a map of PV power plants in China by 2020, covering a total area of 2917 km 2. We found that most PV power plants were situated on cropland, followed by barren land and grassland, based on the derived national PV map. In addition, the installation of PV power plants has generally decreased the vegetation cover.

Does China need a comprehensive map of PV power plants?

With the world's highest cumulative and fastest built PV capacity, China needs to assess the environmental and social impacts of these established PV power plants. However, a comprehensive map regarding the PV power plants' locations and extent remains scarce on the country scale.

What is the spatial resolution of photovoltaic power generation station data?

The photovoltaic power generation station data (PV_China_2020) in China in 2020 were obtained from the GEE platform, using the random forest algorithm. The data sources were Landsat images, and the spatial resolution was 30 m . In contrast, our PV map (2021_PV) had the higher spatial resolution of 10 m. ...

Can machine learning map PV power plants across China?

This study developed a workflow, combining machine learning and visual interpretation methods with big satellite data, to map PV power plants across China. We applied a pixel-based random forest (RF) model to classify the PV power plants from composite images in 2020 with a 30 m spatial resolution on the Google Earth Engine (GEE).

Can spectral and textural features identify PV panels in coastal China?

Here, we developed a new approach that uses spectral and textural features to identify and map the PV panels there were in coastal China in 2021 using multispectral instrument (MSI) and synthetic aperture radar (SAR) images, and the Google Earth Engine (GEE), to differentiate PV panels according to their underlying surface properties.

What is the kappa coefficient of PV power plant in China?

in China is shown below (Fig. 5a). The PV power plant end of 2020. In the machine learning classification process, CS2 (T able 3). The kappa coefficient (kappa), overall accu- the CS1. The kappa, OA, UA of PV and NPV, and P A of PV and 89.89 % for the CS2, respectively (Table 3). Mongolia, respectively (Fig. 5b). The result based on the land
