Correct Road Shapes in Google Maps - "Follow the Blue Line"

On December 13, 2021 I wanted to show how it is now possible to add roads in Google Maps with the new Road Editor for Desktop: Roads for Everyone - Helping others with the New Road Editor. The new editor was officially presented by @KarolinaPysz (whom we all know because she moderates the Road Mapper board) on December 8, 2021, inthe presentation video of this year’s Guiding Stars.

If you are still unable to add roads in the desktop version of Google Maps (I have added more than 750 roads since December 2021) you should read the post, to be ready when the update will also reach your profile.

In the meantime the program has undergone some evolution from the graphic point of view, and an incredible new function has been added: The possibility of correcting the shape of an existing road.

Fixing the shape of a road can be very useful, but it is a feature that should only be used when absolutely necessary. I usually use it in three cases:

  • When I add a missing road, to improve the general information of the area. I don’t think doing this gives me extra points, but since I’m editing an area, I try to do it as best I can.
  • When the area has completely changed (for example because new buildings have been built) and some roads have been moved to adapt to the new road system.
  • When, due to the wrong shape, the Blue Line of Street View is fragmented.

In this post I want to talk about this last case, and that’s why I wanted to add “Follow the Blue Line” in the title.

Follow the Blue Line

It all started when, on December 21st, @L-C highlighted how the Blue Lineof one of the roads in the area related to my post was fragmented, and wondered if “With this tool would it be possible to edit the road shape to improve the map quality?

At that time the new feature didn’t exist, and all I could do was report that the road was “Drawn Incorrectly”. My edit was “Not Applied” in no time.

On February 20, 2022 the new function magically appeared on my desktop, and the first thing I did was to correct the shape of that road.

The result was fantastic, and within days the street began to populate with Street View images. In the cover photo above you can see the street as it appeared before my edit, and during the edit operations. The blue line shows my drawing, and the dashed white line shows the “original” street.

In the screenshot below you can see how the road now appears in Maps, with the Blue Line fully visible and connected

Since that day, hunting for Blue Lines has become a passion for me. I have begun to understand the reason for the missing Blue Lines, and I am trying to fix them. I currently have numerous Pending Edits, and will update the post when they are approved.

What I want to show you below is one of the edits that took the longest, and that hasn’t been approved yet. I still don’t know how many points I will receive for this edit (maybe 5) but certainly seeing the Blue Lines reappear is a much greater satisfaction than receiving the points

Why does the Blue Line disappear?

If any of you also contribute in Street View by adding Photo-Paths and Blue Lines by uploading videos with the Street View App, you will certainly have received messages in which you are told that it is not possible to upload the video because the GPS track of the video does not coincide with that of the street.

In most cases this is certainly true, however the fact that this also happens to Google makes me think, and my conclusion is that it is often the shape of the road that is wrong, not the Street View GPS track.

According to my observations, when the shape of the road is displaced 10 meters or more from the actual position, the Blue Line does not appear. Below you can see a couple of examples, with the detail of the distance.

Obviously this situation is a pretty “extreme” example, and I’m curious to see how soon Google will approve my edit. I wanted to share this situation to make it clear how important it can be to make an appropriate edit.

Have you ever encountered similar situations? If so, I’m sure you too are waiting for the new Road Editor to be available to everyone.

Great post @ErmesT , thanks for sharing. I definitely have to do some catching up to do now that I have seen you are at 750+ roads added already :wink:

Haha, @JanVanHaver

Well, I don’t see this a s a competition, but as a way to improve the quality of the information. Broken Blue Lines are an interesting example of the symptom of an issue that can be easily fixed. Let’s wait for the approval of the latest edits, to see if the blues lines will appear again.

This is only one of the several ways that we have to help. Another interesting experience will come soon.

In my area there is a lot to do about Blue Lines and missing roads, especially in the mountains, but I have tried successfully to fix also some road abroad.

If you are looking for increasing your ranking I can share some area of Europe with you :wink:

To tell you the truth @ErmesT , I had never seen a broken blue line before reading your post - but that is also due to the fact that I’m usually using my phone to explore Maps and never have the StreetView layer on. But now you have triggered my curiosity :wink:

I think you should try to explore on desktop the area around this Abbey, @JanVanHaver .

You will see a lot of broken Blue Lines around there. Here below a small detail of the issue, and in the

Recently I saw many people obtaining access to this new tool and started using it. This worked well in a lot of places including some remote Russian towns such as Kharp or Mexican roads that recently received brand new Street View imagery but with broken blue lines (now they are fixed).

However this new tool is still not available for me and many others. I don’t know what are the prerequisites to have it but it doesn’t seem to be related to Local Guide level, amount of approved edits in the past or being a member of the Road Mapper program as I have more approved edits or higher LG level than most of the people I’ve seen using the new tool. The remaining possibility would be geographical reasons (maybe Google released the tool in a few countries and Canada, where I currently live, is not included yet) or simply random people gets it. If any Googler read this, it would be nice to know more about the current deployment progress or a way to enable it to Road Mapper users as both tools are similar.

This new tool is going to be crucial for the future of Street View because Google made a dramatic change in its data validation in September which broke hundreds of thousands of blue lines all over the world. In short, a blue line needs a road on the map to exist and if the road is either missing or misplaced too much then the blue line will not appear. Google lowered the threshold from around 45 meters to 10 meters, which is way too low. 10 meters is not even the width of a road with more than two lanes! This is why you will find many broken blue lines everywhere, way more than before. This is also amplified by the fact Google Maps is often quite poor in terms of precision, notably in areas where good satellite imagery is not available:

Unfortunately — and despite being aware of the problem — Google will not revert this breaking change… so the only solution left is us having to do the job using this new tool. We already have a group of volunteers to help fixing the roads and the blue lines, some already started as shown above. Sometimes I would like to know what’s up in the mind of whoever manages the Street View program because lately it’s been a disaster and the current state of Street View is really depressing: broken blue lines, navigation capabilities severely reduced, no new added countries for years… The golden age of Street View, when Google was proudly announcing its introduction in new countries with events, is sadly far behind us.

Unfortunately @ErmesT I don’t have access to the feature yet, but I will be in the starting blocks already to be prepared once it gets rolled out here.

This is an interesting post. I wasn’t aware of the new road editor with desk top returning to the maps again !!! I’ll be looking out for it then. Drawing roads for me are very slow now and I only get 1 approved out-of a 100 maybe so it’s quite uphill. Nevertheless I have about 168 roads now so it’s not a ZERO Lol. Looking out for the roll out of this new feature whenever that would be. Thank you.

Cheers

Wow. 168 is indeed a great number, @SholaIB :+1:

@ErmesT Out of curiosity, since you started editing roads with this tool, what is the ratio of approved / rejected edits?

The ratio with the regular tool is quite bad (more rejected than approved) probably because it is mostly processed by automated systems. I would like to know if this new tool allows a better workflow in Google’s validation, like it is in Road Mapper.

Also unrelated to this thread but is there a way to ping Connect moderators in a message? I found a topic in the Road Mapper forum that is just a copy paste of one of my comments. This would be considered as spam but I don’t know how to report it. Thanks.

Thanks for asking, @L-C . Let say that my ratio of approval is more than 98%. If I am not wrong I have around 10 not approved road, and 788 approved in my profile (that tomorrow will probably become 800+, looking at the email received today from Maps)

The accuracy that you can have on desktop is impressive, and sometimes you have satellite images that are not yet public. In this last case the zooming possibility is quite impressive.

Just to give you an example, here below a parking area near the airport in my city

Regarding you second question, I’ve reported that post already, don’t worry, highlighting the original message too, and tomorrow it will be removed :wink:

You can report it too. The one here below is the faster way to contact a Google Moderator

@ErmesT Thank you for your reply. 98% really is an amazing score. And very interesting to see different satellite data being used with it. This makes me want using it even more, I wish I could have it already.

As for reporting posts, it is only possible to do it for replies, not for the original post (OP) of a topic. I don’t see any report button for OPs. This is why I asked. Anyways thank you for cleaning the copied message.
