The Code-for-Atlanta team needs the polygon for Savannah GA to support their treepedia project. This is an example of how to extract the information from an open data source published by Savannah Area GIS Open Data portal.
Could do this with simple command line utility, but wanted to explore the data set so decided on a notebook.
-
Data directory contains the input shape file from SAGIS
-
Data directory will be used for the output geojson file.
-
Notebooks directory contains the notebook to display and extract required data
-
Notebook can be explored with binder
I use jupyter lab with ipywidgets and ipyleaflet for my development. It may not be the standard. I've tried to seperate a base environment with the needed analysis packages. Anaconda is required with this approach. This is the way I do it so your mileage may vary.
-
Assuming anaconda is installed, environment.yml can be used to build a baseline lab env with conda:
conda env create -f environment.yml -
Activate the new env:
conda activate savannah -
Once the python env is done set up the js packages with:
jupyter labextension install @jupyter-widgets/jupyterlab-manager jupyter-leaflet -
At this point you will have a working jupyter lab with the necessary widgets and executing jupyter lab inside the savannah env will start a local version of jupyter lab
