In a few days the TRAC campaign started by @SholaIB will start again with the aim of adding as many roads as possible to Google Maps.
One of the problems often faced is that which concerns Bridges, underpasses and overpasses, or more generally we could say “roads that intersect passing one under the other, without touching each other, that is, without being connected to each other”.
The common belief is that it is impossible to add these roads, as the newly added segment will always also attach to the existing road.
This is not true, it is absolutely possible to draw two overlapping roads without them being connected to each other.
Just accept a simple principle: It is not important to know which road passes above and which passes below.
What is REALLY important is that during navigation we are not asked to continue on a road thatis not connected to the one we are on!
I hope we all agree on this point, so let’s see how it’s done, and above all when to use this method and when to absolutely avoid it.
For our example let’s take any two roads that intersect each other.
In the first example neither of the two streets is in Google Maps. Let’s imagine that at the intersection covered by the yellow dot there is a bridge.
To have two roads on different levels we must make two edits:
1) draw and submit the first road
2) Draw and submit the perpendicular road
Result: The two roads will be overlapped, without any intersection point.
Warning: NEVER perform this procedure on intersecting roads. If the roads must intersect, insert them in the same edit or wait for the first edit to be approved before making the second one.
In the second example, one of the two roads is already in Google Maps. This procedure is a little more complex, requiring three steps and a lot of attention.
It seems impossible, right? Experience teaches us that if we draw a new road passing over an existing one, the two roads will be on the same plane, with an intersection point, as you see below.
To have two roads on different levels we must make three connected edits:
1) Delete the road that is already in Maps
2) Draw the road that passes over the existing one (which we just deleted)
3) Cancel the first edit, to restore the removed road
Result: The two roads will be overlapped, without any intersection point.
Simple right? The only thing to remember is to restore the deleted road before submitting the edit.
How do you do it? This is easy. In fact, the edit menu shows us all the changes made to the map during our edit. To cancel one, just throw it in the trash.
This concludes the first episode of Editing Roads Tips and Tricks.
We learned:
- That we cannot connect another road to a road that has not yet been approved.
- To create two roads that pass one above the other without intersecting.
- To cancel a series of instructions in the editor by throwing them in the trash.
