Some useful tools and guidance using NASA's Black Marble Products
Python scripts to read, convert (GeoTiff), and display (QGIS) VNP46 files. If you do not have GDAL install, you can use the QGIS python console (Plugins -> Python Console) to run the script.
Below are some details on using the tool
Location of the input folder containing HDF images
Current script only reads the first file (if there are multiple files in the input folder).The rasterFiles[ ] index can be modified to select one specific file, or iterate through all files within the input folder
hdflayer = gdal.Open(rasterFiles, gdal.GA_ReadOnly)
Reading specfic raster layer - GetSubDatasets() for first layer, GetSubDatasets() for second layer, and so on
Location of the folder for output images
outputFolder = "C:\\OutputFolder\\"
Display output GeoTiff image in QGIS (Only if the script is executed within QGIS python Console)
