Team:Terrain/Map Data Sources

Current Map

Right now it's stored as a kart repository at Uglyhack's Gitlab. This is just the raw data, we haven't figured out the best way to share the styling yet.

Height Data

The terrain is interesting for terrain features. The rice fields in particular are hard to judge for height. But the team found a open data voxel height map data: Map Data

Link

This can be downloaded from here:

• Maaiveld
• Oppervlaktemodel

These files have also been put in the nextcloud.

Satelite data

The dutch government provides a bunch of data here: link. If you log in you can get a bunch more pictures, including some of previous events.

For general high-res images, pdok has nice layers. You can add them with this WMTS link in QGIS:

   https://service.pdok.nl/hwh/luchtfotorgb/wmts/v1_0?request=GetCapabilities&service=wmts

Some relevant images have been saved on the nextcloud as Geo-referenced TIF files.

BGT data

This is available from the dutch government though their API: https://api.pdok.nl/lv/bgt/ogc/v1

The easiest way I have found to use it is to convert to geopackage.

For example, this script will get it all for the terrain:

#!/bin/bash

cat json | jq -r ".collections[].id" | while read -r dataset ; do
   echo "Download $dataset"
   ogr2ogr -overwrite -of GPKG -spat 110750 522600 112600 523600 -where "eind_registratie IS NULL" -s_srs EPSG:28992 -t_srs EPSG:28992 bgt.gpkg OAPIF:https://api.pdok.nl/lv/bgt/ogc/v1 $dataset
   echo "Resting..."
   sleep 5s
done

You may want to remove the empty layers. Just drag the whole file into QGIS, select all the layers, right click and select "Show feature count". Now remove all the layers with no features.

If you just want the features that have something in our area:

#!/bin/bash
# These are the relevant data sets

    echo "Download $dataset"
   ogr2ogr -overwrite -of GPKG -spat 110200 521900 114500 524000 -where "eind_registratie IS NULL" -s_srs EPSG:28992 -t_srs EPSG:28992 bgt.gpkg OAPIF:https://api.pdok.nl/lv/bgt/ogc/v1 $dataset
   sleep 5s
done

This can then be imported into a postgis database using this command

ogr2ogr -f PostgreSQL "PG:host=host port=5432 user=terrain password=password dbname=qgis" -lco "schema=bgt" bgt.gpkg
