Database¶

Gisaf uses a Postgis database.

Creation¶

To create an appropriate database, run these commands:

createuser avgis -P
createdb avgis -O avgis
psql avgis -c "CREATE EXTENSION postgis;" 

Notes¶

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

Import files¶

Development¶

See the README file

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:

cd gisaf-app
ng build --prod --build-optimizer=false --vendor-chunk

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

cd gisaf-app
ng build --prod

Plugins¶

Gisaf can load models in external plugins. See plugins.

Configuration¶

TODO: more about parameters of the conf file

Map¶

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

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

Production¶

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

Development¶

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

Third party¶

TileServer¶

Serve the vector tiles for mapbox-gl locally: TileServer
