## Usage
|
|
|
|
|
|
|
|
This software is meant to be installed as a hosted installation for
|
|
|
|
several maps. This is done by putting the files in the `frontend`
|
|
|
|
directory on a web server so they appear as `/common/*`, and then
|
|
|
|
creating a directory for each map, with the maps appearing at
|
|
|
|
`/$mapname/`. This directory should contain a `strecken.pmtiles`
|
|
|
|
containing the vector tiles, as well as a `layers.json` containing
|
|
|
|
metadata, and the web server should be configured to display
|
|
|
|
`/common/index.html` when accessing `/$mapname/`. This can be achieved
|
|
|
|
on nginx with the following snippet:
|
|
|
|
|
|
|
|
```
|
|
|
|
location ~ /.+/$ {
|
|
|
|
rewrite ^/(.*)$ /common/index.html last;
|
|
|
|
}
|
|
|
|
```
|
|
|
|
|
|
|
|
The `strecken.pmtiles` file is best generated using the
|
|
|
|
`mapbuilder.sh` script. Furthermore, exporting maps from umap is
|
|
|
|
possible using the `umap-extractor.py` script, which takes care of
|
|
|
|
exporting the data as well as the graphical style for each layer.

### Input Data
|
|
|
|
|
|
|
|
The input data for `strecken.pmtiles` consists of a `data/` folder,
|
|
|
|
with one subfolder for each layer. In each of these folders, the lines
|
|
|
|
to be displayed on the map can be deposited in any format understood
|
|
|
|
by [ogrmerge](https://gdal.org/programs/ogrmerge.html), for instance,
|
|
|
|
GeoJSON or gpx.
