crs_units error with add_speed() #5
Description
Message from user Arky (@cleemansen)
Guess this issue has already been reported. Using add_speed() with MoveApps Python SDK results in crs_units error.
Any workaround would be highly appreciated.
app.py
from sdk.moveapps_spec import hook_impl
from movingpandas import TrajectoryCollection
import movingpandas as mpd
import logging
class App(object):
def __init__(self, moveapps_io):
self.moveapps_io = moveapps_io
logging.info(mpd.show_versions())
@hook_impl
def execute(self, data: TrajectoryCollection, config: dict) -> TrajectoryCollection:
""" Testcase """
data.add_speed()
logging.info(f'Welcome to the {config}')
# return some useful data for next apps in the workflow
return data
