h2. Database

Gisaf uses a Postgis database.

h3. Creation

To create an appropriate database, run these commands:

<pre>

createuser avgis -P

createdb avgis -O avgis

psql avgis -c "CREATE EXTENSION postgis;"

</pre>

h3. Notes

The geometry features' metadata MUST be set with the proper SRID, which can be tricky. See below.

h3. Import files

h2. Development

See the README file

h2. Build frontend (Angular)

Until a bug in (Angular build or plotly) is fixed (https://github.com/plotly/angular-plotly.js/issues/15), build the web application (browser side) with:

<pre>

cd gisaf-app

ng build --prod --build-optimizer=false --vendor-chunk

</pre>

Otherwise, this is the standard command for generating the build:

<pre>

cd gisaf-app

ng build --prod

</pre>

h2. Plugins

Gisaf can load models in external plugins. See [[plugins]].

h2. Configuration

TODO: more about parameters of the conf file

h3. Map

The default view of the map can be configured in the gisaf yaml config, eg:

<pre>

map:

  openMapTilesKey: cS3lrAfYXoM4MDooT6aS

  zoom: 14

  pitch: 45

  lat: 12.0000

  lng: 79.8106

  bearing: 0

  style: OSM (vector)

  opacity: 0.3

  tilesUrl: /tiles/data/india-vector.json

</pre>

h3. Production

Gisaf reads the file @/etc/gisaf/prod.yml@ at boot.

h3. Development

Gisaf reads the @~/.gisaf/prod.yml@ file at boot.

h2. Third party

h3. TileServer

Serve the vector tiles for mapbox-gl locally: [[ TileServer ]]
