To follow a screenrecording of the maps explorer, click here.
Clicking on the map viewer will take you to a new tab, click on layers, and select the layer of your interest (for example: Sentinel-4 Diurnal LST for Sicily, Italy).
Clicking on layers will list all the available (public) layers. From the list select Sentinel-4 Diurnal LST for Sicily, Italy. Select filters to change date, time, and customize according to your needs (see the screenshot below). Once customized, click apply for the changes to appear on the viewer.
After the layer is added and customized, you can get data for any point using the GetPoint function. For that click on Draw>Draw a marker and set your marker on any point in the map viewer. See screenshot below.
When you select a point on the map viewer, you get the location details (latitude, longitude) and the value of the selected layer along with the time. You can also get the code in JSON using this function (see image below or the full video).
A screen-recording of the same is also available here.
