First Velocity Parameter Incompatibility with GeodePy

[BatchelorJ]

In the GeodePy v0.4.0 update the method of calculating the first velocity parameters was updated, and changed the required set of input variables:

“This release revises functionality in the geodepy.survey module that computes corrections applied to electronic distance measurements. This includes changes to the parameter types and units in the function geodepy.survey.first_vel_params”

The PynAdjust file pynadjust/surveyconvert/gsi.py is useful for converting the Leica survey data output into the format required by Dynadjust.

This file is used to read the file and classify each type of measurement, as well as adjust the distances measured for the atmospheric conditions recorded at the time of observation, this file uses:

from geodepy.survey import first_vel_params
from pynadjust.surveyconvert.config import readconfig, renameobs, removeobs, first_vel_cfg, stdev_cfg
from pynadjust.surveyconvert.classtools import Coordinate, InstSetup, Observation, reducesetup, first_vel_observations

‘gsi.gsi2msr’ looks for the observation file (.gsi), and a file of the same name that contains a list of the atmospheric corrections (.gpy), and attempts to pass those values onto geodepy.survey.first_vel_params

Since the Geodepy v0.4.0 update, the parameters read and passed between do not match and the process throws back an error.
