A zoomable map of iNaturalist observations made using Datashader and Leaflet.

How to build the visualization

iNaturalist makes available a full dataset of observations, which is what I used to generate the map.

Go to https://www.inaturalist.org/pages/developers and look for the "GBIF DarwinCore Archive" link. Download and unzip the archive, then move the observations.csv to the data directory.

Create a conda environment with the following (note that conda has a machine optimized version of datashader):

conda env create -f environment.yml

The preprocess the observations.csv file to remove unneeded columns, and to convert the lat/long fields to metres.

python preprocess.py

Generate the tiles as follows:

python generate_tiles.py

Then run a webserver to serve them:

python -m http.server 8008

And open http://localhost:8008/
