pyresample.geo_filter module

Filters based on geolocation validity.

class pyresample.geo_filter.GridFilter(area_def, filter, nprocs=1)

Bases: object

Geographic filter from a grid.

Parameters:

  • grid_ll_x (float) – Projection x coordinate of lower left corner of lower left pixel

  • grid_ll_y (float) – Projection y coordinate of lower left corner of lower left pixel

  • grid_ur_x (float) – Projection x coordinate of upper right corner of upper right pixel

  • grid_ur_y (float) – Projection y coordinate of upper right corner of upper right pixel

  • proj4_string (str) – Projection definition as a PROJ.4 string.

  • mask (numpy array) – Mask as boolean numpy array

__init__(area_def, filter, nprocs=1)
filter(geometry_def, data)

Get coordinate definition and data where invalid lon/lats are removed.

get_valid_index(geometry_def)

Calculate valid_index array based on lons and lats.

Parameters:

geometry_def – Geometry definition (ex. SwathDefinition)

Returns:

Boolean numpy array of same shape as lons and lats
