12. Grids¶
Geo2Grid allows users to remap to one or more projected grids. A grid defines the uniform geographic area that an output image covers. Geo2Grid comes with various grids to choose from that should suit most users and their use cases. Some grids are provided for specific writers (like Tiled AWIPS), but can be used for other writers as well. Users can also specify their own custom grids. See the Custom Grids documentation for help with this.
12.1. Provided Grids¶
Below are descriptions for a few of the grids provided with Geo2Grid. For information on all of the grids provided by Geo2Grid see the Grids Configuration YAML File.
The grids’ projections are defined using PROJ.4. Go to the PROJ documentation for more information on what each projection parameter means.
Note
If the grid does not have a parameter specified it will be derived from the data during remapping. This allows for grids that fit to the data (dynamic grids).
