Delete contour lines with their sounding result
Contour lines are no independent data sets and thus can safely be
deleted with sounding results.
In passing, name the primary key as such.

# Quick Start ## Build - To build all components of gemma, simply type `make` on the top level directory of the repro. - To build all components of gemma, with client in demo mode, use `make demo`. - To only (re)build the back end you can use `make gemma`. - To only build the SPA-Client you can use `make client`. - To only build the SPA-Client in demo mode you can use `make clientdemo`. For further details see [docs/DEVELOPMENT](docs/DEVELOPMENT.md), ## Setup Database - You will need a PostgreSQL cluster with PostGIS. - To install the **gemma** schema and roles use the script `./schema/install-db.sh`. - `./schema/install-db.sh --help` shows you available options. Per default the script will create a database named "gemma" and all necessary roles in the postgres default cluster (listening on port 5432). - The script must be run as a user with PostgreSQL super user rights. By convention this is the "postgres" on most systems. ## Setup GeoServer - Install and run GeoServer as described here: http://docs.geoserver.org/stable/en/user/installation/ - Add tables you want to publish as OGC-Service Layers via GeoServer in the database. For example publish the bottleneck areas: ``` INSERT INTO sys_admin.published_services (name, as_wfs) VALUES ('waterway.bottlenecks', true); ``` In case your gemma is already running (see next section), restart it. Published WFS services will be available at `/api/internal/wfs`. Currently, the same layers will also be available as WMS services at `/api/internal/wms`, regardless of the value of `as_wms` in `sys_admin.published_services`. ## Running gemma - Best is to create a configuration file. Copy the example from `example_conf.toml` to get started: ``` cp example_conf.toml gemma.toml ``` - Edit `gemma.toml`, some parameters you probably want to change: * `host` and `port` to make gemma listen on a public interface * `metamorph-db-password` to match the password for your database user * `geoserver-url`, `geoserver-user` and `geoserver-password` to match your instance of GeoServer - `./cmd/gemma/gemma -h` gives you an overview of more available options. - Then start gemma: ``` ./cmd/gemma/gemma ``` ## Proxying OGC services through gemma - Add services you want to publish via gemma (e.g. for same-origin policy compliance reasons) in the database. For example: ``` INSERT INTO sys_admin.external_services (local_name, remote_url, is_wfs) VALUES ('d4d', 'https://service.d4d-portal.info/wamos/wfs', true); ``` In case your gemma is already running (see previous section), restart it. The services will be available at `/api/external/${local_name}`, thus in the example given above: `/api/external/d4d`.
