_Haftungsausschluss: Dieses Repository und die zugehörige Datenbank befinden sich derzeit in einer Beta-Version. Einige Aspekte des Codes und der Daten können noch Fehler enthalten. Bitte kontaktieren Sie uns per E-Mail oder erstellen Sie ein Issue auf GitHub, wenn Sie einen Fehler entdecken._
## Hintergrund
Die Idee, Denkmäler und deren Merkmale auf einer digitalen Karte anzuzeigen, ist während eines Spaziergangs durch Flensburg entstanden. Auf dem Open Data Portal Schleswig-Holstein stellt das Landesamt für Denkmalpflege Schleswig-Holstein eine Denkmalliste zur Verfügung, jedoch leider ohne Angabe der Koordinaten. Wir haben uns entschieden, dies zu ändern und einen Prototypen der Öffentlichkeit zugänglich zu machen, indem wir die Einträge mit den Gebäudekoordinaten ergänzen.
## Datenquelle
Das Landesamt für Denkmalpflege Schleswig-Holstein prüft anhand der gesetzlich vorgegebenen Kriterien den besonderen Wert eines Kulturdenkmals und legt die Maßstäbe, die Methodik für die Erfassung und Pflege sowie den Schutzumfang der Kulturdenkmale fest. Die erhobenen Daten der Denkmalliste werden im Open Data Portal des Landes Schleswig-Holstein zum Download angeboten. Die Kartendarstellung wurde von engagierten Einwohner:innen und ehrenamtlichen Mitgliedern des OK Lab Flensburgs entwickelt.

## Prerequisite
Install system dependencies and clone repository
```
sudo apt install wget
sudo apt install git git-lfs
sudo apt install python3 python3-pip python3-venv
sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt $(lsb_release -cs)-pgdg main" > /etc/apt/sources.list.d/pgdg.list'
wget -qO- https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo tee /etc/apt/trusted.gpg.d/pgdg.asc &>/dev/null
sudo apt update
sudo apt install postgresql-16 postgis
sudo apt install gdal-bin
# install NVM (Node Version Manager)
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash
# download and install Node.js
nvm install 20
# verifies the right Node.js version is in the environment
node -v
# verifies the right NPM version is in the environment
npm -v
git clone https://github.com/oklabflensburg/open-monuments-map.git
```
Create a dot `.env` file inside the project root. Make sure to add the following content and repace values.
```
BASE_URL=http://localhost

```
## Update repository
```
git pull
git lfs pull
```
## Create SQL schema
Run sql statements inside `open-monuments-map` root directory
```
psql -U oklab -h localhost -d oklab -p 5432 < data/denkmalliste_schema.sql
psql -U oklab -h localhost -d oklab -p 5432 < data/denkmalliste_geometrien_schema.sql
```
Next add administrative geometries
```
ogr2ogr -f "PostgreSQL" PG:"dbname=oklab user=oklab port=5432 host=localhost" "data/vg250gem.geojson" -nln vg250gem
ogr2ogr -f "PostgreSQL" PG:"dbname=oklab user=oklab port=5432 host=localhost" "data/vg250vwg.geojson" -nln vg250vwg
ogr2ogr -f "PostgreSQL" PG:"dbname=oklab user=oklab port=5432 host=localhost" "data/vg250krs.geojson" -nln vg250krs
ogr2ogr -f "PostgreSQL" PG:"dbname=oklab user=oklab port=5432 host=localhost" "data/vg250lan.geojson" -nln vg250lan
ogr2ogr -f "PostgreSQL" PG:"dbname=oklab user=oklab port=5432 host=localhost" "data/vg250rbz.geojson" -nln vg250rbz
ogr2ogr -f "PostgreSQL" PG:"dbname=oklab user=oklab port=5432 host=localhost" "data/vg250sta.geojson" -nln vg250sta
```
Next initialize python virtualenv and install the dependencies
```
cd tools
python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt
python insert_monuments.py ../data/stadt-flensburg-denkmalschutz.geojson
python insert_boundaries.py ../data/denkmalliste_geometrien.geojson
python insert_nearest.py
deactivate
```
## HOW TO USE
To query a boundary of an monument call this script with an `object_id`
```
python3 query_boundary.py 4677
```
```json
{"crs": {"properties": {"name": "urn:ogc:def:crs:OGC:1.3:CRS84"}, "type": "name"}, "features": [{"geometry": {"coordinates": [[[10.473906, 54.268938], [10.474305, 54.268966], [10.474323, 54.268879], [10.473924, 54.26885], [10.473906, 54.268938]]], "type": "Polygon"}, "properties": {"object_id": "4677"}, "type": "Feature"}], "type": "FeatureCollection"}
```
To query an administrative geometry with a buffer by 350 meters
```
python3 query_monuments.py Wiedenborstel
```
```json
