SSH login with user gis

ssh -l gis <server-dns-name>

Start screen

screen

You may close SSH console while command is running. After new SSH login continue with

screen -r

Close screen with

exit

Create data folder

cd ~
mkdir data

Download and install Flight Contest maps server

cd ~/data

ln -s ~/fcmaps/otm/mapnik/data .

OSM data

Download data (Europe)

cd ~/data
mkdir osm && cd osm
wget http://download.geofabrik.de/europe-latest.osm.pbf

Create database gis2

dropdb gis2
createdb gis2
psql -d gis2 -c 'CREATE EXTENSION postgis;'

Load OSM data into OSM database (~/data/osm/*.pbf → gis2)
(Germany, Austria, Switzerland, Poland, Czech Republic, Slovakia, Hungary, parts of France, parts of Denmark)

osm2pgsql -d gis2 --slim --drop --flat-nodes=FILENAME --bbox 1.0,42.0,24.0,55.0 --style ~/fcmaps/osm2pgsql/fcmaps.style ~/data/osm/europe-latest.osm.pbf

Wait… (37h)

Preprocessing

cd ~/fcmaps/otm-dev/mapnik/tools/
psql gis2 < arealabel.sql
psql gis2 < stationdirection.sql

Wait… (10min)

psql gis2 < viewpointdirection.sql
psql gis2 < pitchicon.sql
psql -d gis2 -c 'ALTER TABLE planet_osm_point ADD COLUMN otm_isolation text;'
bash update_lowzoom.sh

Wait… (20h)

Activate new databases gis and lowzoom

dropdb gisold
dropdb lowzoomold
psql -d postgres -c 'ALTER DATABASE gis RENAME TO gisold;'
psql -d postgres -c 'ALTER DATABASE gis2 RENAME TO gis;'
psql -d postgres -c 'ALTER DATABASE lowzoom RENAME TO lowzoomold;'
psql -d postgres -c 'ALTER DATABASE lowzoom2 RENAME TO lowzoom;'

Change date

cd ~/fcmaps
nano printmaps_webservice_capabilities.json

Restart server

Check database size

psql -d postgres -c "SELECT pg_database.datname, pg_size_pretty(pg_database_size(pg_database.datname)) AS size FROM pg_database;"

Contour data

Download all necessary SRTM tiles, see http://www.viewfinderpanoramas.org/Coverage%20map%20viewfinderpanoramas_org3.htm

cd ~/data
mkdir srtm
cd ~/data/srtm
nano list.txt

Insert the following (for Germany)

http://viewfinderpanoramas.org/dem3/N32.zip
http://viewfinderpanoramas.org/dem3/N33.zip
http://viewfinderpanoramas.org/dem3/M32.zip
http://viewfinderpanoramas.org/dem3/M33.zip
http://viewfinderpanoramas.org/dem3/L32.zip
http://viewfinderpanoramas.org/dem3/L33.zip

Save it and continue with

wget -i list.txt

Move zip files to folder germany and unpack all

mkdir germany && mv N*.zip germany && mv M*.zip germany && mv L*.zip germany
for zipfile in germany/*.zip; do unzip -j -o "$zipfile" -d germany/unpacked; done

Fill all voids (*.hgt → *.hgt.tif)

for hgtfile in germany/unpacked/*.hgt; do gdal_fillnodata.py $hgtfile $hgtfile.tif; done

Merge into one huge tif (*.hgt.tif → raw.tif)

gdal_merge.py -n 32767 -co BIGTIFF=YES -co TILED=YES -co COMPRESS=LZW -co PREDICTOR=2 -o germany/unpacked/raw.tif germany/unpacked/*.hgt.tif

Convert into Mercator projection, interpolate and shrink (raw.tif → 90.tif)

gdalwarp -co BIGTIFF=YES -co TILED=YES -co COMPRESS=LZW -co PREDICTOR=2 -t_srs "+proj=merc +ellps=sphere +R=6378137 +a=6378137 +units=m" -r bilinear -tr 90 90 germany/unpacked/raw.tif germany/unpacked/90.tif

Create 10m contour data (90.tif → lon*.pbf) (high memory consumption)

phyghtmap --step=10 --start-node-id=1000000000 --start-way-id=1000000000 --max-nodes-per-tile=0 --no-zero-contour --pbf germany/unpacked/90.tif

tif: 14844 x 23256 points, Lon 6...18°, Lat 44...56°

Wait… (4h)

Do these steps for other countries (with different folders and ids). Because of memory consumption of phyghtmap only max. 6 zip files.

Create database contours2

createdb contours2
psql -d contours2 -c 'CREATE EXTENSION postgis;'

Load contour data into contour database (all generated pbf files must be loaded together in one step)

osm2pgsql -d contours2 --slim --cache 12000 --number-processes 10 --style ~/fcmaps/osm2pgsql/contours.style ~/data/srtm/lon*.pbf

Wait… (4h)

Activate new database contours

dropdb contoursold
psql -d postgres -c 'ALTER DATABASE contours RENAME TO contoursold;'
psql -d postgres -c 'ALTER DATABASE contours2 RENAME TO contours;'

Check database size

psql -d postgres -c "SELECT pg_database.datname, pg_size_pretty(pg_database_size(pg_database.datname)) AS size FROM pg_database;"

Configure server

Check server ressources

Find out database size

psql -d postgres -c "SELECT pg_database.datname, pg_size_pretty(pg_database_size(pg_database.datname)) AS size FROM pg_database;"

Configure Flight Contest

Add printserverapi in → Extras → Settings → Config

flightcontest {
  contestmap {
    printserverapi = "http://<server-dns-name>:8181/api/beta2/maps"
  }
}

and restart Flight Contest.
