GeoNotebook

GeoNotebook is an application that provides client/server environment with interactive visualization and analysis capabilities using Jupyter, [GeoJS] (http://www.github.com/OpenGeoscience/geojs) and other open source tools. Jointly developed by Kitware and NASA Ames.

Installation

System Prerequisites

For default tile serving

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

Clone the repo:

git clone [email protected]: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
