GeoNotebook

GeoNotebook is an application that provides client/server environment with interactive visualization and analysis capabilities using Jupyter, GeoJS and other open source tools. Jointly developed by Kitware and NASA Ames.

Documentation for GeoNotebook can be found at http://geonotebook.readthedocs.io.

Installation

System Prerequisites

For default tile serving

• GDAL >= 2.1.0
• mapnik >= 3.1.0
• python-mapnik >= 0.1

Clone the repo:

git clone https://github.com/OpenGeoscience/geonotebook.git
cd geonotebook

Make a virtualenv, install jupyter[notebook], install geonotebook

mkvirtualenv -a . geonotebook

# Numpy must be fully installed before rasterio
pip install -r prerequirements.txt

pip install -r requirements.txt

pip install .

# Enable both the notebook and server extensions
jupyter serverextension enable --sys-prefix --py geonotebook
jupyter nbextension enable --sys-prefix --py geonotebook

Note The serverextension and nbextension commands accept flags that configure how and where the extensions are installed. See jupyter serverextension --help for more information.

Installing geonotebook for development

When developing geonotebook, it is often helpful to install packages as a reference to the checked out repository rather than copying them to the system site-packages. A "development install" will allow you to make live changes to python or javascript without reinstalling the package.

# Install the geonotebook python package as "editable"
pip install -e .

# Install the notebook extension as a symlink
jupyter nbextension install --sys-prefix --symlink --py geonotebook

# Enable the extension
jupyter serverextension enable --sys-prefix --py geonotebook
jupyter nbextension enable --sys-prefix --py geonotebook

# Start the javascript builder
cd js
npm run watch

Run the notebook:

cd notebooks/
jupyter notebook

Configure the notebook:

Geonotebook relies on a configuration for several of its options. The system will merge configuration files in the following precedence:

• /etc/geonotebook.ini
• /usr/etc/geonotebook.ini
• /usr/local/etc/geonotebook.ini
• sys.prefix/etc/geonotebook.ini (e.g. /home/user/.virtual_environments/geonotebook/etc/geonotebook.inig)
• ~/.geonotebook.ini
• os.getcwd()/.geonotebook.ini
• any path specified in the GEONOTEBOOK_INI environment variable.

The default configuration is installed in sys.prefix/etc/geonotebook.ini

Run the tests

# From the source root
pip install -r requirements-dev.txt
tox

# Optionally only run tests on python 2.7
# tox -e py27

Docker Container

System requirements for running the notebook can sometimes prove burdensome to install. To ease these issues we have included a docker container that will run the notebook inside a containerized process.

Vagrant Machine

Additionally there is a Vagrantfile for standing up an instance of Geonotebook within a virtual machine, further instructions can be found here.

Tile Server

By default geonotebook provides its own tile server based on Mapnik and GDAL as a Jupyter Notebook server extension. Assuming system pre-requisites are available this should not need to be configured. Alternately geonotebook may be configured to use a pre-existing Geoserver for serving tiles. A built in geoserver implementation is available as a virtual machine in devops/geoserver/.

Use geoserver for tile serving

First provision the geoserver

cd devops/geoserver/
vagrant up

Second change the vis_server configuration to geoserver in the [default] section of your configuration. Then include a [geoserver] section with the pertinent configuration. E.g.:

[default]
vis_server=geoserver

...

[geoserver]
username = admin
password = geoserver
url = http://127.0.0.1:8080/geoserver
