3.1.2. Information use rules
- 188.8.131.52. Sources of information
The main source of information is whatever the user can collect first-hand: notepad entries, videos, and photographs.
You can consult third-party sources when working on the map, but only if the use of these sources does not break the rules (see the user agreement, etc.).
Sources that infringe on these rules can not be used, even if they are open source and/or on the internet.
Digital and paper maps or diagrams are examples of third-party sources. Websites of institutions and organizations that contain contact information and list working hours are another example of such sources.
- 184.108.40.206. Reliability of information
Only reliable information can be posted on Yandex Map Editor.
If the accuracy or currency of information is in question, then such information can not be posted on YME. In these cases, it's better to describe the item less completely, but be confident in the description's accuracy.
- 220.127.116.11. Completeness of information
We recommend consulting as much information about a given map item as possible. If you can't access important information though, you don't need to enter values for all the item's attributes (or you can just draw the item's shape without assigning it attributes).
- 18.104.22.168. Objectivity of information
All information about a map item should be as objective as possible. In the map item comments, you can state your opinion regarding how the item should be drawn or how its attributes should be assigned, but stating your opinion about the item itself is forbidden. Information of a subjective nature will be deleted from the map.
For example, names like “my house” or comments like “awful hotel” are subjective. Comments like “move the outline from the roof to the foundation” are allowed, but those like “this cafe's food tastes terrible” are not.
- 22.214.171.124. Advertising information
It is forbidden to post advertising on the map.
This does not include contact information (the organization's phone number, a link to its site) or information about the type of activity that the organization engages in.
