Gisaf (for, eg, GIS Auroville Front-end) is a web application that is under development.
Connection to server directly from CSR
To connect to the server directly without going through Aurinoco server, the correct url is
Gisaf uses a Postgis database.
To create an appropriate database, run these commands:
createuser avgis -P createdb avgis -O avgis psql avgis -c "CREATE EXTENSION postgis;"
The geometry features' metadata MUST be set with the proper SRID, which can be tricky. See below.
See the README file
Build frontend (Angular)¶
Generating the build is straightforward:
cd gisaf-app ng build --prod
For the record, there was a bug (Angular build or plotly), now fixed (https://github.com/plotly/angular-plotly.js/issues/15), that forced to build the web application (browser side) with:
cd gisaf-app ng build --prod --build-optimizer=false --vendor-chunk
In practice, because the resources on the VM of the server are limited (memory), one might just build on the development machine (eg. my laptop) and rsync the
Gisaf can load models in external plugins. See plugins.
Short version: when the server starts, it reads the configuration from
The configuration is found from (in order):
The configuration files are relatively easy to understand, and grow with the development and list of features supported by Gisaf.
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
Gisaf reads the file
/etc/gisaf/prod.yml at boot.
Gisaf reads the
~/.gisaf/prod.yml file at boot.
