-## Import OpenStreetMap data
-
-**Hint:** This step may be skipped if you are using [Lean mode](./docs/lean-mode.md).
-
-You need to import road information from OpenStreetMap for the portal to work.
-This information is stored in your PostgreSQL database and used when processing
-tracks (instead of querying the Overpass API), as well as for vector tile
-generation. The process applies to both development and production setups. For
-development, you should choose a small area for testing, such as your local
-county or city, to keep the amount of data small. For production use you have
-to import the whole region you are serving.
-
-* Install `osm2pgsql`. 
-* Download the area(s) you would like to import from [GeoFabrik](https://download.geofabrik.de). 
-* Import each file like this:
-
-    ```bash
-    osm2pgsql --create --hstore --style roads_import.lua -O flex \
-      -H localhost -d obs -U obs \
-      path/to/downloaded/myarea-latest.osm.pbf 
-    ```
-
-You might need to adjust the host, database and username (`-H`, `-d`, `-U`) to
-your setup, and also provide the correct password when queried. For the
-development setup the password is `obs`. For production, you might need to
-expose the containers port and/or create a TCP tunnel, for example with SSH,
-such that you can run the import from your local host and write to the remote
-database.
-
-The import process should take a few seconds to minutes, depending on the area
-size. A whole country might even take one or more hours. You should probably
-not try to import `planet.osm.pbf`. 
-
-You can run the process multiple times, with the same or different area files,
-to import or update the data. However, for this to work, the actual [command
-line arguments](https://osm2pgsql.org/doc/manual.html#running-osm2pgsql) are a
-bit different each time, including when first importing, and the disk space
-required is much higher. 
-
-Refer to the documentation of `osm2pgsql` for assistance. We are using "flex
-mode", the provided script `roads_import.lua` describes the transformations
-and extractions to perform on the original data.

+## 0.8.1
+ 
+- Get the release in your source folder (``git pull; git checkout 0.8.0`` and update submodules ``git submodule update --recursive``)
+- Rebuild images ``docker-compose build``
+- No database upgrade is required, but tile functions need an update:
+  ```bash
+  docker-compose run --rm portal tools/prepare_sql_tiles.py
+  ```
+- Start your portal and worker services. ``docker-compose up -d worker portal``
+
+
+## 0.8.0
+Upgrade to `0.7.x` first. See below for details. Then follow these steps:
+
+> **Warning** The update includes a reprocessing of tracks after import. Depending on the number of tracks this can take a few hours. The portal is reachable during that time but events disappear and incrementally reappear during reimport.
+
+> **Info** With this version the import process for OpenStreetMap data has changed: the [new process](docs/osm-import.md) is easier on resources and finally permits to import a full country on a low-end VM.
+
+- Do your [usual backup](docs/production-deployment.md)
+- get the release in your source folder (``git pull; git checkout 0.8.0`` and update submodules ``git submodule update --recursive``)
+- Rebuild images ``docker-compose build``
+- Stop your portal and worker services ``docker-compose stop worker portal``
+- run upgrade
+  ```bash
+  docker-compose run --rm portal tools/upgrade.py

+  - Migration of database schema using alembic.
+  - Upgrade of SQL tile schema to new schema.
+  - Import the nuts-regions from the web into the database.
+  - Trigger a re-import of all tracks.
+- Start your portal and worker services. ``docker-compose up -d worker portal``

+- Stop your portal and worker services.
+- **Migration with alembic**: required 
+- **Prepare SQL Tiles**: required
+- Start your portal and worker services.
+- **Reimport tracks**: no action required

-# Lean mode
-
-The application can be configured in "lean mode" through the `LEAN_MODE`
-setting in `config.py`. A lean installation is easier to set up, as a few steps
-can be skipped. However, the performance of the application will degrade in
-lean mode, and lots of advanced features will not be available.
-
-Lean mode is meant as an entrypoint to get started with collecting data,
-without the hassle of importing and maintaining OpenStreetMap data.
-
-## Disabled features in lean mode
-
-* No map tiles are generated.
-* The frontend will not show an overview map, only per-track maps.
-* The `roads` database table is not used, neither for processing tracks, nor
-  for generating map tiles.
-* The API will not generate auxiliary information for display on the
-  (nonexistent) map, such as per-road statistics.
-
-## Switch to/from lean mode 
-
-To enable lean mode, set the following in your `config.py` (or in
-`config.overrides.py`, especially in development setups):
-
-```python
-LEAN_MODE = True
-```
-
-To disable lean mode, set it to `False` instead.
-
-For lean mode, it is important that the config variable `OBS_FACE_CACHE_DIR` is
-properly set, or that you are happy with its default value of using
-`$DATA_DIR/obs-face-cache`.
-
-When turning off lean mode, make sure to fill your `roads` table properly, as
-otherwise the track processing will not work. When turning on lean mode, you
-may truncate the `roads` table to save space, but you don't need to, it simply
-becomes unused.
-
-## Benefits
-
-* When using lean mode, you can skip the import of OpenStreetMap data during
-  setup, and you also do not need to keep it updated. 
-* People can already start uploading data and the data is also processed,
-  giving you as a maintainer more time to set up the full application, if you
-  want to.
-
-## Drawbacks
-
-* Lean mode is less performant when processing tracks.
-* Lean mode track processing depends on the Overpass API data source, which may
-  be slow, unavailable, or rate limiting the requests, so processing may fail.
-  We use caching to prevent some issues, but as we depend on a third party
-  service here that is accessed for free and that generates a lot of server
-  load, we really can't ask for much. If you frequently run into issues, the
-  best bet is to manage OSM data yourself and turn off lean mode.
-* Of course some features are missing.

+# Importing OpenStreetMap data
+
+The application requires a lot of data from the OpenStreetMap to work.
+
+The required information is stored in the PostgreSQL database and used when
+processing tracks, as well as for vector tile generation. The process applies
+to both development and production setups. For development, you should choose a
+small area for testing, such as your local county or city, to keep the amount
+of data small. For production use you have to import the whole region you are
+serving.
+
+## General pipeline overview
+
+1. Download OpenStreetMap data as one or more `.osm.pbf` files.
+2. Transform this data to generate geometry data for all roads and regions, so
+   we don't need to look up nodes separately. This step requires a lot of CPU
+   and memory, so it can be done "offline" on a high power machine.
+3. Import the transformed data into the PostgreSQL/PostGIS database.
+
+## Community hosted transformed data
+
+Since the first two steps are the same for everybody, the community will soon
+provide a service where relatively up-to-date transformed data can be
+downloaded for direct import. Stay tuned.
+
+## Download data
+
+[GeoFabrik](https://download.geofabrik.de) kindly hosts extracts of the
+OpenStreetMap planet by region. Download all regions you're interested in from
+there in `.osm.pbf` format, with the tool of your choice, e. g.:
+
+```bash
+wget -P local/pbf/ https://download.geofabrik.de/europe/germany/baden-wuerttemberg-latest.osm.pbf 
+```
+
+## Transform data
+
+To transform downloaded data, you can either use the docker image from a
+development or production environment, or locally install the API into your
+python environment. Then run the `api/tools/transform_osm.py` script on the data.
+
+```bash
+api/tools/transform_osm.py baden-wuerttemberg-latest.osm.pbf baden-wuerttemberg-latest.msgpack
+```
+
+In dockerized setups, make sure to mount your data somewhere in the container
+and also mount a directory where the result can be written. The development
+setup takes care of this, so you can use:
+
+```bash
+docker-compose run --rm api tools/transform_osm.py \
+  /pbf/baden-wuerttemberg-latest.osm.pbf /obsdata/baden-wuerttemberg-latest.msgpack
+```
+
+Repeat this command for every file you want to transform.
+
+## Import transformed data
+
+The command for importing looks like this:
+
+```bash
+api/tools/import_osm.py baden-wuerttemberg-latest.msgpack
+```
+
+This tool reads your application config from `config.py`, so set that up first
+as if you were setting up your application.
+
+In dockerized setups, make sure to mount your data somewhere in the container.
+Again, the development setup takes care of this, so you can use:
+
+```bash
+docker-compose run --rm api tools/import_osm.py \
+  /obsdata/baden-wuerttemberg-latest.msgpack
+```
+
+The transform process should take a few seconds to minutes, depending on the area
+size. You can run the process multiple times, with the same or different area
+files, to import or update the data. You can update only one region and leave
+the others as they are, or add more filenames to the command line to
+bulk-import data.
+
+## How this works
+
+* The transformation is done with a python script that uses
+  [pyosmium](https://osmcode.org/pyosmium/) to read the `.osm.pbf` file. This
+  script then filters the data for only the required objects (such as road
+  segments and administrative areas), and extracts the interesting information
+  from those objects.
+* The node geolocations are looked up to generate a geometry for each object.
+  This requires a lot of memory to run efficiently.
+* The geometry is projected to [Web Mercator](https://epsg.io/3857) in this
+  step to avoid continous transformation when tiles are generated later. Most
+  operations will work fine in this projection. Projection is done with the
+  [pyproj](https://pypi.org/project/pyproj/) library.
+* The output is written to a binary file in a very simple format using
+  [msgpack](https://github.com/msgpack/msgpack-python), which is way more
+  efficient that (Geo-)JSON for example. This format is stremable, so the
+  generated file is never fully written or read into memory.
+* The import script reads the msgpack file and sends it to the database using
+  [psycopg](https://www.psycopg.org/). This is done because it supports
+  PostgreSQL's `COPY FROM` statement, which enables much faster writes to the
+  database that a traditionional `INSERT VALUES`. The file is streamed directly
+  to the database, so it is never read into memory.
