Hi Phil,

I have some experience using Leaflet (Open Street Map) to create Markers, as well as Range of content with shapes like Ellipse, or irregular shapes.
Forgive me if I am completely missing the point of you're email. However, it sounds like you need some kind of 'ping' - which is called every so often (say every minute) which sends data - such as your current location. When you (or anyone) brings up the map on you're website, that data that has been sent overtime will be read on the webpage, generating markers onto the map (or whatever variation) which can be filterd by the hour, day or longer.

I am not aware of a plugin that goes into such detail, but the leaflet js library is likely to have some 'journey-like plugin' but for storing the data and using the data behind-the-scenes, I do not know.

However, something like this is possible. Whether I am the best person for the job -- I honestly do not know. Be interesting in others suggestions are.

I do not post on ALUG often so I am going to reply to social@list.alug.org.uk.
(If I have responded incorrectly, my apologies)

regards,
Martyn

Hello all,

As the N Wales and Wrexham recipients of this will know, I'm not a developer, the Anglian recipients probably don't know me at all but I moved here a couple of years ago. Over the last 15 years I've written a lot about Linux and FOSS for various magazines and websites, but I'm no expert, so bear with me.

Now I'm mostly retired I have a river/canal cruiser. Last year I did a single-handed trip of about 10 days in each direction to a boat show. So that my family could keep track I enabled 'find my phone' on my mobile and gave them the login details. OK as far as it goes but not ideal obvs. I also blogged each day and then wrote it all up for a boat magazine. This year I plan a longer trip - to the Llangollen International Eisteddfod - about 3 weeks each way. I've sorted out WIFi and a laptop charger on the boat so I can blog better, now I'd like to improve the mapping. The ideal would be a map I can embed in a WP page on my website, that updates every few minutes as I travel. GPS from either my phone, or if really necessary a dedicated GPS device.

Does anyone know if such is already possible using OSM + plugins etc? I've had a quick look online but most advice refers to Google maps. Most of the rest gets very technical very quickly. Goes over my head.

Plan B, is there a dev out there looking for a project? Unpaid and 'free' naturally! Would it feasible to create something like FlightRadar' that displayed boat positions on inland waterways? There is already marinetraffic.com for shipping, but that's way too big. I'm thinking of something boat owners could subscribe to that was available online and capable of being embedded in a webpage.
