Does node red have live plotting and tracking functionality for plotting gps data such as latitude and longitude on a world map for implementing into my case.my gps is sending live location in the debug window every 3 minutes.so just wanted to showcase onto a map. [17]

The info was all there in your PDF - simple maths! [image] //example data {lat: 5007.4965 , lon:838.1157 } function floatToGPScoord(num) { var d = parseInt (num / 100) var m = parseInt(num) - (d*100) var s = num - parseInt(num) var coord = d+((m+s)/60) return coord } msg.or…

and what did the msg end up like ? does it look like the format the map would need ?

flows (2).json (5.3 KB) the change node will set the name attribute to apple in this case.but at what position should i fix this node in this case.?And we need to send name property along with data attribute into a single object.example { name:apple, lat:89.78 lon:556.9 } this is the output […

I can't see the change node in that picture ?

@dceejay i understand, according to u how should we set the flow to see the desired output Will it work if we use join node to create a merged object in this case as it can merge key value pairs from one object into another?

my mqtt broker settings are these broker address-maqiatto.com port-1883 username-bachloo.rahul@gmail.com password-ryanrahul topic-bachloo.rahul@gmail.com /test

Ok no problem.Your approach is correct i was just assuming that it might be also a possibility. :slightly_smiling_face: :blush:

set msg.payload.name is the change node which is inturn connected with mqtt node. [image]

What ? I thought you wanted to change the decoded output and send it to the map. ?

yes i want to show latitude and longitude on map.but according to it we have to add a change node inorder to accomplish it.I tried on my flow the change node but it is not showing desired output instead it shows whole message as payload. This was the second output what i got when i connected a func…

Sorry, I'm now lost. You started with an object with lat and lon, and wanted to add a name to it so you could show it on a map. I showed you how the change node could do that. No need to merge anything.
