As already done at the c:geo heatmap.

From mail:

when you add a marker on fsmap and later move that marker by dragging it, right-clicking on it and selecting "Show coordinates" still shows the original coordinates, not the new ones.

Biggest problem will be the extensions. Some of them are old and were not updated for years.

I would like the "Mark tile as dirty" feature to mark the tile with grey opacity to show it as marked dirty, not a popup notice that tells me that the tile is submitted for rendering.

For some years ago, it was a userscript where i press alt-button + mouse click and the tile was faded out to grey, then it was marked as dirty and submitted for rendering. This userscript doesn't work anymore. But may help understand a little what i mean. :)

var code = '
$("#map").on("click", ".leaflet-tile", function(e) {
if (e.altKey) {
$.ajax({
url: this.src+"/dirty",
context: this
}).done(function() {
$(this).fadeTo("fast", .2);
});
}
});';

var script = document.createElement("script");
script.textContent = code;
document.body.appendChild(script);

Since the OSM tiles were moved to a CDN, their status and dirty methods aren't available anymore.

• Open tile / copy tile URL
• Show tile status
• Mark tile as dirty

Can't "Share this location", because the URL is just stuffed in an uncopyable Alert:

Also the other menu item, "Show coordinates", has the same problem.

Currently the opacity of the OSM Mapnik overlay is fixed to 0.5. Make this value user-adjustable. Quick hack available in https://github.com/SammysHP/fsmap/tree/opacity-selector-2.

Edit in OSM:

1. JOSM users will think it will start JOSM.
2. OSM(.ORG) users will think it will start e.g., https://www.openstreetmap.org/edit#map=19/24.18165/120.86516

Therefore perhaps add a second link to also do the latter, or change the wording to "Edit in JOSM".

Markers already have a context menu. Add a new item that shows/copies an URL that points to this marker. This can/must be further extended by adding the marker again when the URL is called (another parameter for the restore view addon).

"Upload" GPX files and show the contents (waypoints, tracks …) on the map. This should be done only in the browser.

IIRC I already tried this some time ago and maybe have some code somewhere.

Error: Permission denied to access object

When moving the map, although the hash is updated in the urlbar. Using Firefox 115.

http://www.sammyshp.de/fsmap/ needs a link somewhere, back to https://github.com/SammysHP/fsmap/ !

1. Now becomes Open Source, as users can find the source! In fact I bet those are the rules of GitHub too.
2. Users can finally read what the site is trying to accomplish, right there on README.md.
3. Users finally find the place to report bugs.

Add and remove layers, change their order and opacity.

It should be possible to move markers (maybe not always so that they cannot be moved by accident).
