24269	"Remote control ""Open remote files"" should allow opening remote GeoJSON, GPX etc."	NeatNit	team	"I want to instruct JOSM to load a geojson or GPX file from a remote URL. For an example use-case, PTNA ( https://wiki.openstreetmap.org/wiki/Public_Transport_Network_Analysis ) could load a bus trip's GPX file into JOSM in an instant. Right now this has to be downloaded and loaded manually with the ""GPX-Download"" button, as can be seen at: https://ptna.openstreetmap.de/gtfs/DE/single-trip.php?feed=DE-BW-bodo&release_date=&trip_id=ddb-90-M70-1-1-32-H-24-Special%23892-44-28

In another instance, I would like to load GeoJSON data from an ArcGIS query directly into JOSM. The query URL is in the format: https://gisn.example.com/arcgis/rest/services/IView2/MapServer/577/query?where=1%3D1&outFields=*&f=geojson - right now I can only do it by saving the result to a local file using a web browser and loading the file manually in JOSM.

The remote control preferences have a permission for ""Open remote files"", but it only seems to allow geotagged images and nothing else: https://github.com/search?q=repo%3AJOSM%2Fjosm%20ALLOW_WEB_RESOURCES&type=code

It would be amazing if this same functionality was extended to allow loading of other file/data types supported by JOSM.


Also, even this functionality is not documented - the API description of /open_file makes no mention of its ability to load URLs, and only mentions local files:

> /open_file — ''opens a local file in JOSM''
> mandatory parameters: filename
> examples:
> /open_file?filename=/tmp/test.osm

However this seems to work: http://127.0.0.1:8111/open_file?filename=https://upload.wikimedia.org/wikipedia/commons/c/cd/London%2C_London_Eye_--_2016_--_4801.jpg (found by galen on Discord)


So this is a feature request to allow remote loading of more data file types, and also to more fully document the API endpoint. Thanks!"	enhancement	new	normal		Core
