SVG is very generic and is used to draw 2D figures in HTML applications and doesn't care about geography.
KML, GeoJSON and OSM elements have been designed to represent generic geographical points and shapes.
GPX is more specific, having been designed to represent routes and tracks and its semantices are directly useable in our application.
The strucure of our components and indexes can therefore follow the GPX format.
OSM elements is interesting to extract information from the OSM DB, either by querying their API or by downloading portions of the database.
GeoJSON might be of interest as an intermediate format since a number of JS libraries have been developped to perform queries or draw GeoJSON data as SVG.
KML might be considered as an import format.
And SVG, of course will be used to render tracks and routes on a map since its elements are directly supported by React.
This can be done by updating their sources in the node_modules directory and using the patch-package npm CLI command (thanks [stackoverflow](https://stackoverflow.com/a/13302095/1402881)) :
```
$npx patch-package localized-strings
```
However, it takes ages before `ionic serve` takes these modifications into account.
