Does 0.1.dev2 from conda-forge include TrajectoryManager?

[jonititan]

Sad error here.
Clean install into dedicated environment on Windows 10.
environment.yml records version as

movingpandas=0.1.dev2=py37h39e3cac_0

When trying to use the TrajectoryManager class from the tutorial it fails saying the module has no such attribute.

I can't see any releases on github so wondered if conda has lagged behind github?

[anitagraser]

Yes, TrajectoryManager has only recently been added and is not yet available via conda

[anitagraser]

The Notebooks in https://github.com/anitagraser/movingpandas/tree/240020788a8798b56727506b7490acbfff364f3d should work with the conda version

Hi, does this mean that we cann't yet use our own data until TrajectoryManager is available?

[jonititan]

The only problem I had was with regard to plotting. I was able to get it into Geopandas just fine and then convert to Movingpandas trajectory by passing a dataframe of points. In my case it was aircraft points during a flight. You can still use the mpd.Trajectory class

[anitagraser]

Alternatively, you can also use the development version by following the instructions in https://github.com/anitagraser/movingpandas#development-installation

That's a very good alternative! When I load my data as a gpkg geopackage everything works just fine. However, reading a csv finally gives an error with the TrajactoryManager: 'DataFrame' object has no attribute 'crs'

[anitagraser]

For CSV, we have to specify the CRS manually, because there is no metadata section to read it from:

gdf = geopandas.read_file(path_to_csv)
gdf.crs = {'init' :'epsg:4326'}
gdf.plot()

Thanks. The read_file method returns max recursive errors or dead kernels, however when I first use read_csv and then convert to a geodataframe it works!
I haven't been able to get the trajectories (TimeManager objects) into qgis yet.

[anitagraser]

@djoostwoud I started a QGIS plugin that adds MovingPandas functionality to the Processing Toolbox: https://github.com/anitagraser/qgis-processing-trajectory. It should give you a general idea of how trajectories can be used in QGIS.

The plugin development is currently on ice until MovingPandas has reached at least 1.0 release status.

The new movingpandas 0.2rc1 includes TrajectoryCollection (formerly called TrajectoryManager) https://anaconda.org/conda-forge/movingpandas
