Say you have a node A in one location and you want to link it with a node B at another location to extend the mesh (join the two meshes). The node A covers a certain region and a node B covers another region, and there is no line of sight between the two nodes. You may then need a third “hopping” node to link the mesh of node A to the mesh of node B. How can you find out if this is even possible for your landscape topology, and where then to put the third “hopping” node?
Using the site https://www.heywhatsthat.com/ you can plot the horizon and visibility cloak (locations with a line of sight) of each node by creating a “new panorama” for each location
The nice thing about the above site, when seeking to plan a “hopping” node location to join nodes, is the following:
when you have made a panorama for the location of node A and selected “horizon” and “visibility cloak”
you see what you need for location A,
but then when you make a new panorama for the location of node B, the horizon of the previous location A remains shown on the visibility cloak map of location B provided you did not yet select the “horizon” button for location B. So you can still see the horizon of the location of node A inside the visibility cloak of node B. This allows you to see easily where, within the horizon of location A, there might be locations within the visibility cloak of location B. These locations, if they exist, would be ones where one could place a third “hopping” node to connect two nodes A and B.
The image below shows an example - there is only one region in the red-marked visibility cloak of location B that falls within the horizon of location A. That make the existence, or non-existence, of a potential location for a node to link the two locations easy to see on the map
In the example above it probably shows that that it would be a severe challenge indeed to link the mesh of node A with the mesh of node B using a single third “hopping” node - because there are really no multiple choices of location for such a hopping node, and the one there is might not be at all suitable nor accessible.
Having found if there exists at least one potential location within the horizon of node A, the visibility cloak of the node A can be made (selected) and then used to see if there is a location that is:
(a) within the horizon of node A and
(b) within the visibility cloak of node B, is also
(c) in the visibility cloak of node A.
Thereby you can assess where nodes might be able to be placed to extend the mesh to neighbouring regions. Testing such location might require considerable teamwork.
