Extract GeoJSON from Esri Shapefile

Import Data from GeoJSON file

To use the prefered names and tools run this lines

git clone https://github.com/oklabflensburg/open-accident-map.git
cd open-accident-map
sudo -i -Hu postgres psql -U postgres -h localhost -d postgres -p 5432 < data/unfallorte_deutschland_schema.sql
cd tools
python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt
for i in {16..23}; do python3 ./insert_accidents.py ../data/accidents_20$i.geojson; done
deactivate

In case you dont want to use default import use this

ogr2ogr -f "PostgreSQL" PG:"dbname=postgres user=postgres host=localhost port=5432 password=postgres" "data/vg250.geojson" -nln vg250
ogr2ogr -f "PostgreSQL" PG:"dbname=postgres user=postgres host=localhost port=5432 password=postgres" "data/accidents_2016.geojson" -nln accidents -append

ogr2ogr -f "PostgreSQL" PG:"dbname=postgres user=postgres host=localhost port=5432 password=postgres" "data/accidents_2023.geojson" -nln accidents -append

Create Indexes

ALTER TABLE accidents ADD COLUMN wkb_geometry GEOMETRY(GEOMETRY, 4326);
ALTER TABLE accidents ALTER COLUMN wkb_geometry TYPE GEOMETRY(GEOMETRY, 4326) USING ST_GeomFromGeoJSON(geometry);
CREATE INDEX IF NOT EXISTS accidents_wkb_geometry_geom_idx ON accidents USING gist (wkb_geometry);
CREATE INDEX IF NOT EXISTS vg250_wkb_geometry_geom_idx ON vg250 USING gist (wkb_geometry);
ALTER TABLE accidents DROP COLUMN geometry;

Reindex GIST

REINDEX INDEX accidents_wkb_geometry_geom_idx;
REINDEX INDEX vg250_wkb_geometry_geom_idx;

Webserver

Setup frontend webserver configuration for nginx

server {
    listen 80 default_server;
    listen [::]:80 default_server;

    charset uft-8;

    add_header Content-Security-Policy "default-src 'self' https://nominatim.openstreetmap.org; script-src 'self' https://unpkg.com; img-src 'self' data: https://unpkg.com https://tile.openstreetmap.org; style-src 'self' 'unsafe-inline' https://unpkg.com; font-src 'self'; worker-src 'none'; object-src 'none'";

    root /opt/git/open-accident-map;
    index index.html;
}

Test configuration

Test configuration and install certificates, make sure to uncomment http2 after certbot run.

sudo nginx -t
sudo certbot

Start webserver

sudo systemctl start nginx.service
sudo systemctl status nginx.service
sudo systemctl enable nginx.service
