Installation

Create a geo aware database. See Geodjango doc for backend installation.

Create a virtual environment

virtualenv umap
source umap/bin/activate

Install dependencies and project

pip install umap

Create a default local settings file

wget https://raw.githubusercontent.com/umap-project/umap/master/umap/settings/local.py.sample -O local.py

Reference it as env var:

export UMAP_SETTINGS=`pwd`/local.py

Add database connexion informations in local.py, for example

DATABASES = {
    'default': {
        'ENGINE': 'django.contrib.gis.db.backends.postgis',
        'NAME': 'umap',
    }
}

Add a SECRET_KEY in local.py with a long random secret key

SECRET_KEY = "a long and random secret key that must not be shared"

uMap uses python-social-auth for user authentication. So you will need to configure it according to your needs. For example

AUTHENTICATION_BACKENDS = (
    'social_auth.backends.contrib.github.GithubBackend',
    'social_auth.backends.contrib.bitbucket.BitbucketBackend',
    'social_auth.backends.twitter.TwitterBackend',
    'django.contrib.auth.backends.ModelBackend',
)
GITHUB_APP_ID = 'xxx'
GITHUB_API_SECRET = 'zzz'
BITBUCKET_CONSUMER_KEY = 'xxx'
BITBUCKET_CONSUMER_SECRET = 'zzz'
TWITTER_CONSUMER_KEY = "xxx"
TWITTER_CONSUMER_SECRET = "yyy"

Example of callback URL to use for setting up OAuth apps

http://umap.foo.bar/complete/github/

Adapt the STATIC_ROOT and MEDIA_ROOT to your local environment.

Create the tables

umap migrate

Collect and compress the statics

umap collectstatic
umap compress

Create a superuser

umap createsuperuser

Start the server

umap runserver 0.0.0.0:8000

Search

UMap uses Postgresql tsvector for searching. It case your database is big, you may want to add an index. For that, you sould do so:

CREATE EXTENSION unaccent;
CREATE EXTENSION btree_gin;
ALTER FUNCTION unaccent(text) IMMUTABLE;
ALTER FUNCTION to_tsvector(text) IMMUTABLE;
CREATE INDEX search_idx ON leaflet_storage_map USING gin(to_tsvector(unaccent(name)), share_status);

Optimisations

To speep up umap home page rendering on large instance, the following index can be added too (make sure you set the center to your default instance map center):

CREATE INDEX leaflet_storage_map_optim ON leaflet_storage_map (modified_at) WHERE ("leaflet_storage_map"."share_status" = 1 AND ST_Distance("leaflet_storage_map"."center", ST_GeomFromEWKT('SRID=4326;POINT(2 51)')) > 1000.0);
