Exploring Animal Density Data

⭐️ Check out the dashboard here!

TL;DR - If you want to jump right into the code the notebooks folder is a great place to start!


The data used in this project are from MGEL Density Models: US East Coast. If you'd like to replicate this work, you can either download the full zip file containing all of the data, or you can download individual density files. The data in the data folder are all .gitignore'd because they're large. But the folders are organized as follows:

|--data
    |-- density
        |-- Atlantic_spotted_dolphin_v9.1
        |-- Atlantic_white_sided_dolphin_v4.1
        |-- etc...

To provide examples of how you can extract relevant statistics, we're using shapefiles from BOEM's Renewable Energy GIS Data site
