polyfemos.front.sohplot.offsets.UWVOffsets

class polyfemos.front.sohplot.offsets.UWVOffsets

Bases: object

A class for UWV to NEZ conversion

The transforming function for each sensor is defined in transform_func()

Public Methods

__init__()

clear()

Initializes self.offsets attribute into it’s default value.

isnan()

Checks if every value (U, W and V) is defined. If every one is defined, the coordinate transformation can be done.

Return type

bool

Returns

returns False if the coordinate trasformation is possible.

transform(sensor, component)

Transform offsets, UWV to NEZ

Parameters

• sensor (str) – Which transformation function is used, defined in transform_func()

• conponent (str) – Which component after transformation is returned, N, E or Z.

Return type

UTCDateTime, float

Returns

timevalue and value of N, E or Z offset

update(dtstr, key, value)

Stores given value to offset U, W or V.

Parameters

• dtstr (str) – datetime compatible string or other value compatible with UTCDateTime

• key (str) – Which offset is updated, U, W or V

• value (str) – string representing float value of the offset,

Special Methods

__bool__()

Return type

bool

Returns

returns True if the coordinate trasformation is possible.
