Viewing TLEs, interactive selection of AIS tracks and drilldown #4

Work in progress.

Uses datashader to view positions of TLE records in 2017 (Notebook/Viewing_TLEs.ipynb):

TLEs

The second notebook (Notebook/Viewing_AIS_Paths.ipynb) prototypes the use of spatialpandas to build a spatially indexed dataframe that allows interactive selection and viewing of AIS tracks:

zone10-selection

Next steps

Visualize tracks for a small number of chosen satellites.
Improve interactive selection of tracks to pick single nearest voyage.

I have now added Notebook/AIS_Drilldown.ipynb that prototypes the addition of a metadata table for drilldown that is populated when you select vessels at a chosen time:

drilldown_PR

Improved the Viewing_TLEs notebook:

Now viewing the full 2017 file (~300MB)
Improved the styling and colormap:

300mb_TLE

Beautiful, thanks!

Added the Viewing_AIS_Categorical notebook for categorical datashading of AIS data:

I've now updated the Viewing_TLEs notebook to allow interactive viewing of the precomputed tracks around the TLE epoch:
