A selection of scripts to download WWSG data from the DTP API and DAV API (work in progress) for JOSM import/update preparation

Overview

A selection of scripts to download WWSG data from the DTP API and DAV API (work in progress) for JOSM import/update preparation

As usual:

python -m venv .venv
.\.venv\Scripts\activate
pip install -r requirements.txt

Output and results are provided as examples, based on DTP and OSM data as of Sep 20, 2024

Procedures

Note: There is no sanity checking for missing dependecies, etc. !

DTPAreas2GeoJson.py

Extracts all cat=x geometries from DTP endpoint and produces, supports caching of DTP data to speed up runs during code tweaking Runs for a couple of minutes unless rebuild_cache = False

Outputs:

• ./geojson/cat_18-19.geojson (mostly german alps)
• ./geojson/cat_20-41.geojson (mostly austrian alps)

Import to geoserver (on xctrails.org):

ogr2ogr -f "PostgreSQL" PG:"dbname=schongebiete user=postgres" ./cat_18-19.geojson -nln dtp_18_19 -overwrite

-> https://www.xctrails.org/schongebiete/SchongebieteWMSLayer.html

GeoJsonAreaDiff.py

Compares OSM Schongebiete geometry with new geometry (from DTP)

Inputs:

• ./geojson/cat_18-19.geojson
• https://www.xctrails.org/osm/Schongebiete.geojson (downloaded in script, 1:1 from cat_18-19.geojson)

Output:

• output/new-areas-josm.geojson as input for JOSM updates (don't re-copy DTP attributes into OSM in that case!)
  • shape import/merges in JOSM: see https://www.xctrails.org/videos/JOSM-Shape-Korrektur.mp4
• output/new-areas.geojson with all properties (possibly for new imports - manually check all tags in JOSM !!!)
• osm2dtp_mapping.csv - as input for GenerateJosmScript-DTP_ID.py (only used once)

IdMappingReport.py

DTP -> OSM Category 18/19 mapping status report removed and missing areas based on osm_id in DTP data

Inputs:

• cached DTP data
• live/cached OSM data

Outputs:

• ./reports/dtp2osm_report.html
• ./reports/dtp2osm_report.csv"

TagDiff.py

Inputs:

• ./geojson/cat_18-19.geojson - from DTPAreas2GeoJson.py
• https://www.xctrails.org/osm/Schongebiete.geojson (downloaded in script)

Outputs:

• ./reports/tagdiff_report.html
