gull_tracking: modernized project example

[Azaya89]

• Modernized example
• Added explanations for the code
• Discuss hosting the file on our S3 due to the lack of the content-length in the response from Zenodo preventing any progress bar to be displayed by anaconda-project?

However, I left the lnglat_to_meters function as is since I don't know the equivalent function from hvplot.

The utility to convert the coordinates is the HoloViews hv.util.transform.lon_lat_to_easting_northing function. You've seen it in use already in the HoloViz tutorial (https://holoviz.org/tutorial/Composing_Plots.html). Can you please update the code to use it instead?

I've left some other comments, good start! :)

I feel it would be good to describe more the dataset before displaying it. I'd suggest showing the output of df.head() and len(df). The output of df.describe() wouldn't be very interesting, I think, as we only read the lat/lon columns (the CSV has more columns). The text says there are 2.4 million points in the dataset but as someone looking at this example I'd rather see the output of a code cell show that :)

I was a bit stumped by the fact that the map wasn't centered on the dataset. Running the notebook, I found out that there are 4 points farther West and North.

(These data points are actually displayed on the map, but they're very small and have a dark color. We use dynspread=True to deal with this kind of case, maybe its settings like threshold and max_px need to be adjusted to better display these isolated points. @jbednar)

I think the example would look better if there was a plot focused on where most of the points are. For example, after removing these points (e.g. df = df[(df['location-long'] > -14) & (df['location-lat'] < 53.3)]), the map looks better I think:

I stored a copy of the file on our S3 and updated the anaconda-project.yml accordingly.

LGTM! Thanks for the latest changes, merging :)
