This is a docker setup for a "quick" install of a server like opentopomap.org.
The config files and scripts in this image are directly taken from:
https://github.com/der-stefan/OpenTopoMap
A multi processor server with at least 16 GB RAM and a lot of HD space.
A full worldwide server needs about 3 TB of HD to host all tiles up to zoom level 17.
You need docker and docker-compose to run this image.
You don't need this repo locally if you use the prepared Docker Image:
jhassler/otm-docker:latest
You can find this image on Dockerhub: https://hub.docker.com/jhassler/otm-docker
You only need this repo if you want to build your own image variant. See below: Build your own image.
With this image you can setup an OSM tile server with the Opentopomap style.
You can choose which part of the world you want to cover. Everything is possible, from a single country up to the whole world.
Create a directory and put the docker-compose.yml file into it. This file is a copy of the docker-compose.yml.dist file
in this repository.
Create the directory data inside your project directory with these subdirectories:
mkdir -p data/data
mkdir -p data/db
mkdir -p data/letsencrypt
Then edit your docker-compose.yml and change the following variables:
- LETSENCRYPT=0: Change this to 1 if you want to obtain SSL certificates through Let's Encrypt. Use this on a production server.
- EMAIL=[email protected]: Change this to a valid E-Mail address. This will be used to setup the Let's Encrypt SSL certificates. You can leave it if you use the image only locally.
- DOMAIN=localhost: Change this to the domain (URL) of your OTM server. This will be used inside the Apache configuration.
- WHITELIST=127.0.0.1: You can add an IP here that will not be affected by the mod_file throtteling.
This image will expose the HTTP ports 80 and 443 to the outside. Make sure they're not used by some other services on your server. If you want to host the OTM server on a different port, change the outside port section, e.g. change "80:80" to "8080:80" - then your server will be available on port 8080 from the outside world.
You need a PBF file of your favourite region. This can be the full 48 GB planet file (https://planet.openstreetmap.org) or some regional extract. You can find a good list of servers in: https://wiki.openstreetmap.org/wiki/Planet.osm
Download your PBF file and put it into your project data/data directory with the name osmdata.pbf.
The script expects the data to have this name.
Download some elevation data files and put the into the local directory data/data/srtm. You have to create the srtm directory.
Here are some locations for elevation data:
- https://dds.cr.usgs.gov/srtm/version2_1/
- http://viewfinderpanoramas.org
- http://www.imagico.de/map/demsearch.php
- http://data.opendataportal.at/dataset/dtm-europe
The files should be in HGT format compressed as ZIP files. The files will be extracted and converted in the script 04_dem_hillshade.sh.
Make sure the SRTM data covers the region you chose in step 2.
Easiest way: For worldwide SRTM data use:
http://viewfinderpanoramas.org/dem3/M31.zip
http://viewfinderpanoramas.org/dem3/M32.zip
http://viewfinderpanoramas.org/dem3/M33.zip
http://viewfinderpanoramas.org/dem3/L31.zip
http://viewfinderpanoramas.org/dem3/L32.zip
Your directory structure should look something like this:
docker-compose.yml
data/data/osmdata.pbf
data/data/srtm/some-zip-file1.zip
data/data/srtm/some-zip-file2.zip
data/db
data/letsencrypt
Then start the thing:
docker-compose up -d
Check output with docker logs otm-docker -f
This will create your postgres database and start some services. They won't really come up, but the container should be running.
This is only needed once. You have to start some scripts to import your data.
docker exec -ti otm-docker bash
Inside start a screen session. Then you can start the long running scripts and don't stop them when you log out.
screen
Once you've started some scripts, press CTRL+a d to detach from the screen session. Then logout of your container
with exit. If you come back later and login to your container again, you access the session with screen -r.
Make some adjustments to the scripts depending on your available memory:
- /scripts/import_osm_data.sh: Change
MEMORY=12000to the MBs of memory you have available inside the Docker session
Execute the following scripts in the given order:
cd /scripts
sh 00_setup_database.sh
sh 01_download_water_polys.sh
sh 02_import_osm_data.sh
sh 03_dem_hillshade.sh
sh 04_preprocess_osm_data.sh
sh 05_dem_contours1.sh
sh 06_dem_contours2.sh
Step 2 (import OSM data) takes the most time, depending on the size of your PBF file. A full planet can even take DAYS to import.
Step 5 (generating the contours data) can also take a long time and needs a lot of RAM, min. 16 GB for the world SRTM. If you get a memory fault when executing, then try it with lower resolution or on a box with more RAM.
Once everything has run through, you log out and restart your container:
docker-compose down
docker-compose up -d
Now you should see your map by accessing your server's mapdemo directory, e.g.: http://localhost/mapdemo
The tile layer is available with the following URL http://your-server/otm/{z}/{x}/{y}.png. You can include it in your favourite mapping applications.
Rendering your tiles on demand usually takes too much time. It's better to pre-render them in the background. You can do that with Tirex. To render e.g. all tiles in Switzerland for zoom levels 1-16, this command can be used:
tirex-batch -p 5 -d map=opentopomap bbox=6.0,45.78,10.44,47.83 z=1-16
mod_tile considers a tile as "old" if it's older than 3 days and triggers a re-render. If you want to prevent all re-renders and manually re-render the tiles by controlling Tirex, you can start the container with the following env var:
MOD_TILE_PREVENT_EXPIRATION=1
DOCKER_BUILDKIT=1 docker build -t otm-docker:latest .
