Greasemonkey script for easy river drawing

[EduardoCarvajal]

Hi,

This is a modified version of Street to River Script that I call Street to River PLUS.

Mini howto:

1.install this script from userscripts.org as Greasemonkey script, Chrome extension or Tampermonkey script.

To add a new river:

1.Draw a new street but do not save the Street.
2.Add and apply a street name to define the rivers name and the width of the river.
Example: "20m Spree" creates a 20 meters width river named "Spree".
3.Select the helper Street.
4.Click the "Street to river" button.
5.Delete the helper Street.
6.Edit the new landmark as you like.

To expand an existing river:

1.Draw a new Street that starts inside an existing river, but do not save the Street.
2. Make sure that you see on map the begining of the street (the instersection point of the street and the river)
3.Select the helper Street.
4.Click the "Street to river" button.
5.Delete the helper Street.
6.Edit the new landmark as you like.

Version 13.10.20

1. Unlimited river size option added.

Version 13.10.18

1."Twisted" river problem solved

Version 13.10.09

1. Added support to multilingual version of Waze editor.

Version 13.6.3.1

1.Added support to Google Chrome and Tampermonkey.
2.Now it's possible to expand an existing river.
3.Fixed save problem on large rivers.

This seems to sometimes work correctly, but occasionally (after one or two modifications and saves?) incorrect two nodes are chosen for landmark continuation, not these two, where the segment crosses the landmark borderline between them.

Foxitrot, I prefer to draw rivers using small streets segments. I have more control, it's very fast and easy, and if something goes wrong you only lose the last changes you made to the map.

If you extend an existing river, make sure that before you press Street to river button, you see on screen the beginning of the street (the area where the street and the river intersect). If you draw a very large street to expand an existing river, and scroll the map, sometimes Waze editor unloads the river from memory, so the script concludes that this is a new river because it doesn’t find any river in computer memory that intersect with the helper street.

Please make sure that you have the latest version of the Script.

Street to River 13.10.17

Sincerely,
Eduardo.

Waze editor is limit to 40 changes between savings. If you draw a very long and complex street, the river will be truncated to the first 40 points (changes). This is by design, and it’s imposed by Waze editor (if you don’t believe me, manually draw a very complex river, with more the 50 changes, and try to save it).

Your description sounds pretty reasonably, just... where have you got the "at most 40 changes between savings" limit in the editor? To check it, I've just manually drawn a river landmark polygon with over 100 nodes and it immediately saved - flawlessly. Whenever I'm modifying any forest's landmark, you can bet I make a couple of hundreds of changes between saves...

Either the system works (exceptionally it does happen) and you can make nearly any number of changes between saves, or you constantly get save errors...

[edit]OK, Now I see the culprit:

Code: Select all

    // 2013-06-03: Reach waze limit?
    if(polyPoints.length > 40){         
        break;
    }


Extending it to e.g. 440 solves the problem. I recommend you discarding the code block completely, WME does not have such limit. If the Save fails, then the problem is somewhere else (unfortunately it is mostly impossible to guess, where).

I've drawn maybe a 1 km long street and then pressed the STR button. Just the first hundred meters of my river were created. Then I've deleted the corresponding first few hundred meters of my helper street and pressed it again - another hundred meters of river were created (actually, my river landmark got correctly extended by the length). And so on and so on... until the end of my segment was reached.
Did it behave as expected?

Hi,
Waze editor is limit to 40 changes between savings. If you draw a very long and complex street, the river will be truncated to the first 40 points (changes). This is by design, and it’s imposed by Waze editor (if you don’t believe me, manually draw a very complex river, with more the 50 changes, and try to save it). If you need to draw a very large river, draw a small street, press Street to River button, then press delete button (to delete the helper street) and save changes. Then add a new street that starts inside the recently created river and repeat the process. Believe me, this is faster than manually drawing a river.

Additionally, I've tried to extend an existing river landmark, but it often got the river sides twisted at my extension pont, possibly because of the not matching order of points around the two polygons. Could this be taken into account when extending an existing polygon?

Version 13.10.10 solves this issue. To dowload the latest version:

This gets me grumpy

[An error occurred while saving]

I draw a massive long river then I get this error and I have to start all over

Does any body else get this or is it just me?

I've seen this a lot, and I've tracked it down to corners where two points cross over each other. WME really doesn't like Landmarks that become twisted (kinda hard to describe).

Solution is to check the whole stretch of river, looking for pairs of geometry points that are very close together. Usually found near sharp corners of the river, and you might notice a missing point nearby. Delete one of the pair, and save. Repeat as necessary.

That's true although it doesn't always help. And that's when it gets really annoying. Sometimes it just won't save no matter what you try.

I do. Nowadays I just draw a bit shorter "rivers" and adjust the borders. Bit annoying though. I think the problem is on Waze's side. Not the only saving problem you know..

I can't get this script to install/work in chrome, any tips

Google Chrome 18.0.1025.151 m

You seem to be using tampermonkey? (If yes, then) stop using it and install again. That worked for me.

P.s. read the thread before posting. The answer was already there.
