How do I understand the metadata (meta.json) file?

Your metadata file will display information that looks something like this, though the information will vary based on the provider, resolution, etc. Please see the outline below:

• Satellite: This is the specific name of the satellite that captured your image.
• Capture time: This is the date and time that your image was captured, written year-month-date and time in GMT (Greenwich Mean Time). 
• GSD meters: GSD stands for ground sample distance and is the spatial resolution of the captured image and represents the size of each pixel in meters. 
• Cloud percentage: This is the total cloud cover of the swath from which your image was cropped, which is likely a much larger image than what you received. It may not be representative of the cloud cover specifically present in your cropped image. 
• Satellite off nadir: This is the angle at which the satellite was looking when it captured your image. 0 degrees would represent the satellite looking straight down and the off nadir angle represents how far left or right the satellite was looking from straight down.
• Solar elevation: This identifies the angle of the sun at the time the image was taken. 90 degrees would represent the sun being directly overhead of the object being captured.
• Satellite azimuth: This identifies the direction to the satellite in reference to the central object on the ground based on a 0-360 degree compass. For example, a satellite azimuth angle of 0 means the satellite is looking straight south to capture the image. 
• Solar azimuth: This identifies the direction of the sun in reference to the central object on the ground based on a 0-360 degree compass. For example, a solar azimuth angle of 120 degrees means that the sun is directly southeast of the image. 
• CRS: This stands for coordinate reference system, and the number represents the coordinate system being used for the data, which will be important when using the image in geospatial softwares. We typically use the local UTM zone for your data. 
• Band order: The order of the bands in the GeoTIFF will be listed here, with R representing red (i.e. band 1), G representing green (i.e. band 2), B representing blue (i.e. band 3), and NIR representing near infrared (i.e. band 4). 
• No data value: This will always be 0 by default and means that where you see a 0 (or do not see any image) there is no data present. 
• Processing level: This is the level of processing that has been applied to the data. Ortho indicates orthorectification and is our standard processing level. 
• Data bits: This is the bit-depth of the GeoTIFF representing the sensitivity of the data. This is our standard GeoTIFF delivery file, which is why the TIFF file may not display correctly in a standard photoviewing application.
