Bug inserting a rectified map in a umap map

[EmilieLerigoleur]

Hi Tim,

I discovered https://mapwarper.net/ because I'd like to add an old orthorectified map to my umap map as a base layer. It's really nice and useful!

I've run several tests but using the URL ‘Tiles (Google/OSM scheme)’ doesn't work. For example, https://mapwarper.net/maps/tile/36892/%7Bz%7D/%7Bx%7D/%7By%7D.png returns a white image.

A 500 error is sent to umap server. Could you please help me solve this problem?

Here's the link to my test card. You can edit directly inside! https://umap.openstreetmap.fr/fr/map/remarkable-trees-in-the-city-of-metz-france_1224927

Many thanks,

This may be an issue with umap Note the way the URL is encoded within umap when you enter it as https://mapwarper.net/maps/tile/36892/{z}/{x}/{y}.png https://mapwarper.net/maps/tile/36892/{z}/{x}/{y}.png on it's own isn't a valid image, it has the placeholders {z} {x} {y} needed for the basemap https://mapwarper.net/maps/tile/36892/14/8478/5619.png for example works. Hope this helps in the meantime, Tim
