# 3.19.1. General information about HD maps

{% note alert %}

Not all YME users can create and edit HD maps.

{% endnote %}

1. To accurately identify road markings when drawing HD maps, use satellite images, Yandex panoramas, dashboard images, and aerial photos. Consult GOST 32953-2014 (Road markings) to determine the correct marking type.

    To stop highlighting a layer for easier drawing , disable **Layer interactivity**. To do this, click the pencil in the layer line:

    {% note warning %}

    The roadbed layer must be fully complete before you start adding any markings (areal, linear, or point). Always start HD mapping with the Roadbed layer.

    When drawing road markings, refer to the Interstate Standard for Road Markings (GOST 32953-2014).
  
    {% endnote %}

2. We recommend drawing at scale 21.

3. **Don't draw** **temporary** markings on the map, except for bike lanes.

    {% note info %}

    Check the box next to the **Temporary** parameter in the linear marking card only for temporary bike lanes and their markings.

    {% endnote %}

4. If a particular marking type **doesn't exist** in Yandex Map Editor, **don't draw** it.

5. If you can't identify the road markings based on the latest data due to weather conditions (for example, wet asphalt, snow‑covered road, or a dirty windshield), you may use slightly older data.

6. If the most up‑to‑date source shows that the road markings are missing due to road surface replacement or repairs, map the road based on the latest source where the markings are still visible.

    An exception applies when you can see that the roadbed width physically changed. In this case, **don't draw** the markings.

7. If the traffic direction contradicts the most recent photos and satellite images, draw only the roadbed.

8. For faded or partially erased markings, follow these rules:

    - **Draw** them if there are signs that the markings have partially faded due to weather or time — for example, if the fading on this section isn't limited to a specific marking type.

        If you see that some markings on the road have been updated while others haven't (even if partially faded), draw the old markings provided that the new ones supplement rather than contradict them. For example, if only linear road markings have been updated while the point markings are partially damaged but otherwise untouched, you should draw both the linear and point markings.

    - **Don't draw** them if you determined that a specific road marking element or type has been erased deliberately while others remained untouched.

9. If the markings are outdated and no longer fit logically into the current traffic pattern, don't draw them.
