OpenSeaMap for boaters on MAP component

[StampMax]

Hello,

I understood that

@SteveJG

App Inventor way to use OpenStreetMap tiles is to use the Map components which addresses the OpenStreetMap api using a control.

I'm just wondering if there a easy way to use OpenSeaMap for boaters applications
I'm working on a navigation companion app and it would be nice to have OpenSea instead OpenStreet.
Nevertheless OpenStreet and Map component is absolutely a great tool to code with! Thanks

Someone has implemented support for providing alternative map servers (assuming they are still using WebMercator projections) but it hasn't been merged yet. Assuming the OpenSeaMap uses the same URL patterns as OpenStreetMap, it certainly would be feasible once that feature is merged.

That's what I suppose, but create an extension is really out of my skills .

Who suggested creating an extension ?

One way:
Sorry, thought I had a link to the api. Did not though I understand it is similar if not a fork of the OpenStreetMaps api.

Another way:

Use the WebViewer to access the OpenSea url. I made an app to do that with OpenStreetMaps a long time ago.

This example seems to work Test it and improve it. Two ways to use OSeaM are shown. Both provide your present location coordinates on the map using the LocationSensor. Comments are appreciated. Not fancy but does not require the api or an extension.

Use the provided tools to change what is displayed on the map. Tested on an Android 13.

Hello @SteveJG , sorry for ask, but i think the link of opensea, is not the openseamap. I found the link is a NFT website.

Requesting API keys

is not...

https://map.openseamap.org/

Your example is of the last one. (but i go to the nft from your link). Is that right?
Sorry if is my mistake.

• You seem to be correct about the api link posted. Thanks. I have deleted the reference.

• the example is using the openseamap.org web page.
  here is some explanation of what the aia project I posted does.

Test it and improve it

Thanks @SteveJG ... this is not immediate and reacting as MAP component but on the other hand it has several inbuild functions. I'll work on it.

First target is to arrange the window and understand how to pan efficiently
