Dear Thingspeak Community,

The whole implementation of a separate and single Lat/Lon/Alt value under Thingspeak Channel settings that is not editable remotely with an API write key, as far a I know, has been a bit difficult. This is compounded by the confusion of having an identically named data field Lat/Lon/Alt that is not related to the channel setting Lat/Lon/Alt single value and not plotted natively on a map without maybe a plug-in or Matlab Mapping toolbox finagling.

Is there a simplistic way to update the mapable Lat/Lon/Alt value found under channel settings remotely using an API write key or an alternate way to automatically update the single channel setting Lat/Lon/Alt value using data from the most recent Lat/Lon/Alt updated using the API write key (same data visible when Location=true) in hopes that the map display will plot the new value? A last option would be a simplistic method to plot the last several Lat/Lon/Alt values written using the API write key would be fine too.

Future suggestions:
1) If there were a way to pull the header information using CSV at some point, that might be neat, as JSON and XML appear to be the only API method to do this and they are slower to retrieve data than CSV API call requests for data when tested in Matlab with tic; toc;
2) A method to view the exact screen visible under the Private tab with all 8 fields and map visible when a user enters and HTML channel address with read API key for channels set as private. It appears that the current method with API read key will only plot and display a single Field Plot for private channels, which is bizarre for a GUI inspired IoT system.

There is a way to update the channel location via the API see the write settings documentation.

You can update the feed location using the normal write operation to the channel. Just add &longitude=long&lattitude=latt&elevation=height to your update api call. see write data.

The channel location represents where the data aggregation or analysis is happening. For example your home. If you were tracking a device with GPS, the device would post to the feed position information.

For example, if you look at this channel I have a channel with a fixed location, but the feeds have location information from walking around the grounds with a soil moisture and temperature sensor with GPS data. Each measurement has a slightly different location, but the channel location is constant. You can see more about the device here .

In your suggestions
1. what do you mean by header information? We are definitely interested in users that retrieve ThingSpeak information from MATLAB.
2. Are you talking about using the charts API? You can see the private view in the web interface. If you want to create a separate interface that looks like the web interface in MATLAB, you would have to make separate calls. Are you trying to replicate your channel view in MATLAB? this is an interesting use case.

FYI, MATLAB answers is the preferred location for ThingSpeak Community support.
