bolides.fov_utils.get_boundary#
- bolides.fov_utils.get_boundary(boundary, collection=True, intersection=False, crs=None)[source]#
Get specified boundary polygons.
GOES GLM FOV obtained from a netCDF4 file kindly provided by Katrina Virts (NASA/MSFC; katrina.virts@uah.edu) based on information from Doug Mach and Clem Tillier. Fengyun-4A FOV obtained by eye from several papers. Global Meteor Network FOV obtained from KML files at https://globalmeteornetwork.org/data/.
Possible values in boundary:
'goes'
: Combined FOV of the GLM aboard GOES-16 and GOES-17'goes-w'
: GOES-West position GLM FOV, currently corresponding to GOES-17. Note that this combines the inverted and non-inverted FOVs.'goes-e'
: GOES-East position GLM FOV, currently corresopnding to GOES-16.'goes-w-ni'
: GOES-West position GLM FOV, when GOES-17 is not inverted (summer).'goes-w-i'
: GOES-West position GLM FOV, when GOES-17 is inverted (winter).'goes-17-89.5'
: GOES-17 GLM FOV when it was in its checkout orbit.'fy4a'
: Combined FOV of the Fengyun-4A LMI, in both North and South configurations.'fy4a-n'
: Fengyun-4A LMI FOV when in the North configuration (summer).'fy4a-s'
: Fengyun-4A LMI FOV when in the South configuration (winter).'gmn-25km'
: Combined FOV of all Global Meteor Network stations at 25km detection altitude.'gmn-70km'
: Combined FOV of all Global Meteor Network stations at 70km detection altitude.'gmn-100km'
: Combined FOV of all Global Meteor Network stations at 100km detection altitude.
- Parameters
- boundary: str or iterable with multiple strings
Specifies the boundaries desired. Currently supports:
- collection: bool
If boundary contains multiple boundaries,
True
will return a list of boundaries, whileFalse
will return their combination (according to the intersection argument)- intersection: bool
If boundary contains multiple strings and collection is
False
, when True will return the intersection of the fields-of-view, when False will return their union.
- Returns
Polygon
or list ofPolygon
in the Azimuthal Equidistant- Coordinate Reference System with a central latitude of 90, central longitude of 0.
