1.3.5. Error messages on maps

Yandex.Maps users may send messages about discrepancies and errors that they find. You can read about this in the Help section of Yandex.Maps.

You can see these messages and fix the related errors on Yandex Map Editor.

Examples of error processing can be found below in the Error correction examples section

To process errors:

  1. Click Layers .

  2. In the menu that appears, click Show error messages on the map:

    The map will display placemarks that contain error messages. When you hold your cursor over the placemark with the error, a tool tip pops up with the error type:

    These placemarks display as brown circles with exclamation points inside.

    If two or more placemarks are located close to each other, they are grouped together and the number of marks is indicated on the circle. To ungroup the placemarks, increase the map scale.

    If the error has been processed (see below), the placemark will change to a green circle with a check mark.

  3. Click on a placemark. An error-processing card opens:

    The card contains:

    • The type of error (in the drawing: “Incorrect walking route”

    • Date message was created (10.04.2017)

    • Text of message (“There is no crosswalk”...)

    • A What user saw link (available for errors that involve places and routes).

      When you click on Yandex.Maps, the area of the map that the user saw when they reported the error opens. If that area doesn't correspond to the YME area where the error displays, it means that the error was incorrectly linked.

      If you can't tell what actions are required to fix the error based on viewing the map, then don't try to fix it.

    • A What user drew link (available for errors that involve places and routes).

      When you click on Yandex.Maps, the area of the map that contains the places and routes that the user drew opens. If the error concerns an incorrectly set route, then the route builder's suggestion will appear as a blue dotted line, and the route that the user suggested will appear as a gray line.

      If you can't tell what actions are required to fix the error based on viewing the map, then don't try to fix it.

    • The Accept button. Click it to make corrections based on error messages. If you decided not to make corrections, close the card by clicking Close .

      If you click Accept, the message placemark will be highlighted on the map and the error-processing panel will look different.

      At the same time, a My tasks button will display next to the Create button:

      Click that button to go back to your current task.

      The edit counter will appear on the button as you work on the task:

      Note.

      If the counter displays an incorrectly high number of edits (as shown in the drawing), then something probably went wrong.

      Every error-processing card has its own counter. The counter value will not reset, even if you reject a task and then return to it later.

      The error-processing card includes these buttons:

      • Edits unnecessary ─ click this button if the information in the message has already appeared on the map.

      • Reject ─ click this button if the information in the message is incorrect.

        For example, the information might be wrong, incoherent, not relate to items on Yandex Map Editor, contain links to unidentifiable map items, etc.

        You should only reject user requests that are clearly incorrect or intentionally misleading.

        Sometimes messages contain useful information that the user just couldn't phrase correctly, or they linked to the wrong item, or they had trouble navigating the area. In these cases, try to “extract” the information by using additional sources.

        For example, if the user reported that a “section of Lenin Ave. is closed for repairs” in the field for the Vladimir region, it's worth checking if Lenin Ave. in Vladimir is indeed closed for repairs.

        If you clicked Reject, the card will look like this:

      • Refuse ─ click this button if you don't know how to correct an error or you are not sure if the information in the message is valid.

        In this case, another moderator can correct the error.

  4. If the message was already accepted, you will switch to the error correction mode. The error-processing card will close and you can start correcting errors. The My tasks button will remain visible and the edits you make will appear on the counter that is connected to it.

    Enter your corrections and click Corrected on the card:

    The card appearance will change:

    The error placemark will change to a checkmark when you do this:

  5. If you've finished correcting the error, click Close.

    If the error requires additional edits, click Reopen.

Error correction examples

  1. If the message states that a building was demolished, check this information. If you can confirm it, select one of the edit options:

    1. If the building is still visible on the satellite image (meaning the image is outdated), set Demolished as the value of the Condition attribute.

    2. If the building is not on the image (i.e. the image is current), delete the item from the map.

  2. If the message claims that there is road construction/sinkholes/lanes repairs, etc., check this information. If you can confirm it, select one of the edit options:

    1. If long-term (more than three months) off-season road construction is taking place, mark that section of road as inaccessible for all types of transport (see 3.3.2.3. Accessible to). Set it to “Under construction” (see 3.3.2.11. Under construction) and lower the class to a “road of minimal significance” (see point 3.3.2.1.7).

    2. If a road is temporarily closed (for less than three months), a planned re-paving is underway, or if there are potholes, river flooding or similar situations that make it difficult or impossible to traverse a given section of road, then leave an error message and a Yandex employee will address it.

  3. If the message states that a street or address don't exist on the map, check this information. If you can confirm it, make sure that the item is not included among the current data and enter it on the map.

  4. If the message contains information about a pedestrian route, follow these rules:

    • Generally, you shouldn't delete existing paths in response to this error message, but rather draw in the sections that are absent.

    • You shouldn't draw in trails formed from stomped-down vegetation, holes in fences, or other unofficial roads that are not intended specifically for pedestrians.

    • If all the necessary roads are already on the map, but the user is claiming that the route was incorrectly set, then make sure that all roads on that route are open to pedestrians.

    • Routes set by the route builder may not match routes suggested by users.

      For example, if the user requests that a route go through a park because they don't want to walk along the road, but their route is longer, then we can finish drawing the park trails, but the route that's set will still be the shortest option.
