Unique name used to identify this product The “vis01” near the top is the “key” in the JSONĭictionary and is described in more detail in later sections. The “vis01” near the top of the file should match the “vis01” specified for Relative to one another does not matter, however, they must always beĬomma-separated. Most of the fields in this text should be fairly self explanatory, but furtherĭetails can be found in the table below. A simple use case describing one product to beĪfter creating a 32-bit float flat binary file named “my_swath_scene.dat”,Ī 32-bit float flat binary file named “lon.dat” and one named “lat.dat”įor the geolocation, create a text file named “my_json.json”.Īnd can be whatever you want. It is recommended that you create one text file JSON is a simple text format that can be read and written by many modern Place all of your flat binary files in the same directory and then create Multiple bands/products that share the same geolocation (no need to make Geolocation files can be reused when processing The longitude and latitude data must also be written flat binary files. In addition to the observation data being written to a flat binary file Polar2Grid normally names its flat binary files with a “.dat” extension. Must be in row-major order (all of row 0, followed by row 1, etc).Ĭurrently 32-bit floats are the only supported data type for these files. No header or other metadata it is just the binary swath data. Create the binary files ¶Įach swath of data that you would like processed must be saved to a file The following sections will describe what has to be done to process theseįiles through Polar2Grid. Polar2Grid’s solution for this isĭescribing the data going in to Polar2Grid and flat binary files (binaryįiles with only data and no header information). With little to no programming experience. Is to provide an intermediate file format that can be easily created by anyone Polar2Grid supports many types of input files, but supporting all possibleįormats and schemes would be impossible to keep up with. This feature is not finalized and will likely change with more userįeedback and as collaboration with the Pytroll team evolves.
