Projections

why we do the reprojections the way we do: http://trac.osgeo.org/proj/wiki/FAQ#ChangingEllipsoidWhycantIconvertfromWGS84toGoogleEarthVirtualGlobeMercator

Install requirements

Node.js is required for the static asset pipeline. If you don't already have it, get it like this:

brew install node
curl https://npmjs.org/install.sh | sh

Then install the project requirements:

cd $NEW_PROJET_NAME
npm install less universal-jst
mkvirtualenv $NEW_PROJECT_NAME
pip install -r requirements.txt

Install server requirements

sudo apt-get install build-essential libwebkit-dev unzip
sudo add-apt-repository ppa:developmentseed/mapbox
sudo apt-get update
sudo apt-get install tilemill
sudo add-apt-repository ppa:ubuntugis/ppa
sudo apt-get update
sudo apt-get install gdal-bin

Adding a template/view

A site can have any number of rendered templates (i.e. pages). Each will need a corresponding view. To create a new one:

  • Add a template to the templates directory. Ensure it extends _base.html.
  • Add a corresponding view function to app.py. Decorate it with a route to the page name, i.e. @app.route('/filename.html')
  • By convention only views that end with .html and do not start with _ will automatically be rendered when you call fab render.

Run the project locally

A flask app is used to run the project locally. It will automatically recompile templates and assets on demand.

workon $NEW_PROJECT_NAME
python app.py

Visit localhost:8000 in your browser.

Compile with static assets

Compile LESS to CSS, compile javascript templates to Javascript and minify all assets:

workon $NEW_PROJECT_NAME
fab render 

(This is done automatically whenever you deploy to S3.)

Test the rendered app

If you want to test the app once you've rendered it out, just use the Python webserver:

cd www
python -m SimpleHTTPServer

Deploy to S3

fab staging master deploy

Deploy to a server

The current configuration is for running cron jobs only. Web server configuration is not included.

  • Run fab staging master setup to configure the server.
  • Run fab staging master deploy to deploy the app.

Rendering the map

To render the map locally:

fab local_render_map

To render the map on the server, you must first define the environment variable MAPBOX_SYNC_ACCESS_TOKEN_WILDFIRES. Then run:

fab render_map

To cron render map on the server:

0,30 * * * * cd /home/ubuntu/apps/us-wildfires/repository && ../virtualenv/bin/fab server_render_map
