The purpose of this app is to provide a way to quickly and easily read latitude/longitude from two fields from a ThingSpeak public channel.

To use the app you need to type in a channel number that has sharing enabled to the public. Then, you can select the fields that contain the latitude/longitude coordinates in decimal format. The fields can be a number from 1 to 8. Selection is made by a dropdown.
You can select the amount of past readings to plot to the map.
Example: If you want to add to the map 50 markers (50 last readings of latitude/longitude) you should click the dropdown named "Insert markers from last X readings" and select "50".

After filling all the information on the settings section, click the "INSERT MARKERS" button to display the markers on the map.

There is also a "live" insertion option, which will read only the last 1 entry from the ThingSpeak channel and insert a marker for that entry. This "live" feature will keep inserting a new marker (the last ThingSpeak entry) every X seconds. X can be an amount of seconds from 10s to 60s.
