Isochrone Demo

---

A short demo of Isochrone polygons from here.com API displayed with ipyleaflet. Inspired by Data Viz Today Podcast Episode 20 and presented as a lightning talk at the August 2018 meeting of Tripython.

Getting Started

---

The easiest way to run the demo is to use Anaconda for your operating system.

Create an environment for Python 3.6 with the required packages.

conda create -n isodemo python=3.6 arrow ipyleaflet requests toml

Activate the environment.

source activate isodemo

To run the UI version of the demo install ipywidgets and appmode

conda install -c conda-forge ipywidgets  
conda install --channel conda-forge appmode  

Go to developer.here.com to sign up for an API key. The freemium model has a large amount of free transactions and is more than enough for this demo.

Clone this repository and create a file named credentials.toml with this format. Note: this is not a secure way to manage secrets in python, but is easy for a demo.

title = "credentials"

[apikeys]

    [api.here]
    appid = "your_app_id"
    appcode = "your_app_code"

Finally, start isochrone-data.ipynb in a Jupyter Notebook.

Running the Notebook

---

Update the address string in the second cell. Then run the notebook.

Drive time ranges from Red Hat Tower in Raleigh.
