csep.core.regions.increase_grid_resolution

csep.core.regions.increase_grid_resolution(points, dh, factor)[source]

Takes a set of origin points and returns a new set with higher grid resolution. assumes the origin point is in the lower left corner. the new dh is dh / factor. This implementation requires that the decimation factor be a multiple of 2.

Parameters
  • points – list of (lon,lat) tuples

  • dh – old grid spacing

  • factor – amount to reduce

Returns

list of (lon,lat) tuples with spacing dh / scale

Return type

points
