If your map looks more like the one on the right, you starting in an area with a [[glossary|base map]]. This is '''good news'''. It means Waze has acquired information about roads in your area. You do not have to manually map most of the roads. This gives you a head start on getting the map to the point where you can use it to plan a route to your destination.
==Incompleteness of the Base Map==
Base maps are supplied with different amount of information, so some base maps are more complete than others. And the information can be inaccurate or out of date
* Roads may have no names. Or some may be named. Some names may not follow the same conventions used for naming roads in your country
* Road types may be missing. Or incomplete. Or not match the conventions used in your country
* Roads may have no city name attached to them
* Roads may be all set to No Entrance. One-way and two-way settings may be absent or wrong
* Roads may be missing or with an incorrect layout
* Junctions may be set to allow no turns, so there is no connectivity between roads. Or connectivity may be incomplete or wrong
* Junctions may be missing, especially on [[glossary|dual carriageways]
 
'''This isn't too bad'''. Even if the base map is the most incomplete it can be, a small city can be made fully mapped by one person in a few hours.
==Requirements==
* You need a reliable source of the names of roads in your area  
* You should be familiar with the agreed conventions for naming roads and setting road types in your [[Countries and Languages|country]]
* You need to decide on a systematic way of working across the map. It can be very difficult to identify roads you have not yet worked on if they look the same as other roads. If the road directionality on your base map is all set to No Entrance, you can see the roads that you have edited. It is impossible to tell by looking whether you have edited a junction, which is why it can be useful to do step 2 at the same time you do a road.
* You need permission to edit the map. Anyone can edit the names and set the properties of roads on a base map. But you cannot change the connectivity of roads or edit junctions without map editing permission. You can gain permission [[timeline of updating process|within a few days]] of driving along the roads with Waze on - this permission extends about to any point within a mile (1.5km) of where you have driven. But you will find it easier and faster to [[Area Manager|apply to be an Area Manager]] for this area
* You need to know how to use Cartouche for [[Map Editing|edit the map]]
 
==Method for completing a Base Map==
If you [[just drive around with Waze turned on]] it will learn to change the road [[glossary|directionality]] to one-way or two-way, correct road layout, and know what turns are allowed at junctions. But there are some things Waze can't yet learn automatically, like the name and types of of the roads.
 
===Name the roads and set their properties===
Note that while this is Step 1, you may find it more efficient to carry out all 3 steps at the same time. The next two steps will happen automatically as [[glossary|wazers]] drive over the roads, but that may take a very long time on seldom used roads. So read on ahead before you get started.
 
Depending on the completeness of your base map, some or all of the information in this step may already be entered.
 
# With a systematic approach, select a road on the map. You can hold the Ctrl key down to select multiple [[glossary|segments]] of the same road. Then from the Edit Panel choose ''Edit Road Details''
# Choose the appropriate [[glossary|road type]] - if in doubt, choose Street
# The country will be filled in for you. If in the USA you may need to choose your state
# Type in your city name. As this will be repeated for every road, highlight the city name and press Ctrl-C to copy the name to the clipboard. Next time, instead of typing it you can press Ctrl-V in the city name box
# Leave the English city name blank unless there is an official city name and a common English name. For example the city name may be 北京 but the English city name would be Beijing
# Next to ''Street'' enter the name of the road
# Set the direction as two-way unless you know the road is one-way. If one-way you have a choice of directions. You may see the road labelled as A-B, so choose One-Way-> for A to B and One-way<- for B to A direction of travel. Once you save changes the road will show arrows in the direction of travel. If it is wrong, select the road again and then choose ''Reverse road direction''
# Click on ''Save changes''
# Well done. Now repeat for the next road. Don't worry if you make a mistake. The roads can all be edited again at any time
 
===Set the [[glossary|connectivity]] of the roads===
Those roads may physically touch on the map but Waze doesn't consider roads to be connected unless they are joined with a junction that is set to allow travel on to the next road. And if they are not connected then Waze won't plan a route along them.
 
Eventually Waze will learn that the roads are connected if you just drive along them with Waze turned on. But you can speed that process if you [[Map Editing|edit the map] to connect the roads.
 
It may be that the base map already includes connectivity, so you can move on to the next step.
 
You cannot tell whether Waze considers two roads to be connected by simply looking, so it is very important that you have a systematic approach to choosing junctions to correct. You may prefer to do it together with step 1 - fixing all the junctions on a road at the same time you enter the details for that road.
 
Waze will automatically restrict and allow turns as appropriate for any intersection combination of one-way or two roads. So you should not place this a junction until the [[glossary|directionality]] of all all connecting roads is set correctly. If you later change the directionality of a road - say make a road one-way instead of two-way - you need to repeat replacing all the junctions on that road.
 
# With a systematic approach, identify a junction on the map
# From the Edit Panel, choose ''Add junction''
# Make sure ''Enable all turns'' is ticked
# Click on the top of the junction you selected
# Well done. Now repeat for the next junction
 
====Adding turn restrictions====
If there is a turn restriction that is not based on one-way status - for example, no left turn is permitted at an intersection, you need to add that restriction in after you place the new junction. To do this:
 
# Select the road you start from
# Hold the Ctrl key down and select the road you are not allowed to turn on to
# From the Edit Panel select ''Create turn restriction''
====Creating a roundabout====
You may wish to change an intersection into a roundabout. Make sure all the roads entering the roundabout are on the map first, so the roundabout directions will be correct. Then follow the instructions on [[how to create a roundabout]]
 
===Add and delete roads and correct their [[glossary|geometry]]===
At this stage Waze can use the map you have edited for routing. [[Timeline of updating process|Within a week]] you will be able to use it. New roads can be recorded and update requests can be sent just as for any other map.
 
But if your base map is not very complete or accurate, you may wish to spend some time adding new roads, deleting non-existent roads and editing the layout (known as geometry) of the roads. You can read the [[Map Editing|instructions]] for all these map editing tasks.

Revision as of 07:19, 4 October 2010

You want your map to look like the one on the left, but you live or have travelled to an area where it looks like the one on the right, or is completely blank.

Waze gives you the power to create a road map yourself and this article explains how. You don't have to do it all, someone else may help you, or do it all, or your country may get a base map.

But it is faster and fun to do it yourself, and you will earn points.

Methods for creating a road map from nothing

Your best approach is to create your own base map by recording new roads. Once you have created this base map, anyone, including you can later use the methods for dealing with a map filled with unnamed roads.

  • Just before you leave a mapped road (or at your starting point if there are no roads on your client map), follow the [[recording a new road|instructions for recording a new road
  • Leave the road recording on unless you return to mapped roads for a significant period of time. Waze tries to be clever and not record new roads where there is already a road in place, but due to inaccuracy in GPS fixes this does not always work
  • We do want a little overlap when moving on and off already mapped roads so start mapping a little before you move off, and turn it off again a little after you return to a mapped road
  • Don't worry if you record new roads in the same place more than once
  • If you are mostly driving on unmapped roads it is safer for you to just leave the road mapping on. Any overlap can easily be fixed later
  • If you do not have network coverage and are not connected to the Waze server at the time you record a new road, it is likely that your road recording will not be saved. However the client app does save your GPS points for transmission when you reconnect to the server, and these GPS points can be used to draw the location of a new road. You may get an increase in storage by turning on use data compression in the Data Usage section of the Settings menu
  • Rather than creating a full or partial base map, you may simply wish to record the routes you travel on. Every road is helpful

Recording roads from the aerial images

  • You may find it easier to create roads based on the aerial images if these are present in your map area at sufficient quality
  • Not that you earn more points driving a new road then adding a road using the map editor
  • Aerial images can be out of date
  • Before you start using the aerial images for making maps in a new area you must check whether the aerial images are accurately positioned by comparing the recording of a known road against the aerial image display. Otherwise all the roads you add on the map may be offset from their true locations and GPS routing will not work

Creating roads when not driving

  • If you are walking, jogging, cycling or travelling by bus over public roads, you can still use Waze to record roads where no roads exist. Any information is better than no information
