It is explained in the wiki:
https://wiki.lazarus.freepascal.org/LazMapViewer#Map_Overlays, and more specifically
https://wiki.lazarus.freepascal.org/LazMapViewer#Overlaying_a_layer_with_points-of-interest.

In short:

* In the object inspector, having the MapView selected, click on the '...' next to the "Layers" property to open the Layer editor.
* Click "Add" to create a new layer.
* In the object tree of the object inspector click on "PointsOfInterest" of the new layer, right-click, "Add" again to add a point of interest
* Select the newly created item "0 - TMapPointOfInterest" and fill in its properties:
o Caption - the text displayed below the point
o Longitude, Latitude - the location of the point in GPS coordinates o ImageIndex - the index of the image that you want to display here. Note that you must assign a TImageList to the POIImages property of the MapView which contains all the needed images. Find a large selection of marker images in the installation directory of the package (the images were kindly provided by Roland Hahn).
