3.9.1. Rules for drawing vegetation items

Drawn in accordance with 2.7.1. General rules for drawing polygonal items.

Draw them regardless of their size (to the extent that the satellite image allows).

The external polygon of vegetation items is drawn based on the actual vegetation boundaries.

You can draw individual trees located at some distance from the greater woodlands area or other trees if they are visible on the satellite image.

Don't draw individual trees within the vegetation polygon (such as a woodland area or garden).

If a tree is a local attraction with cultural or historical significance, draw it as a placemark of the “Locations” category and the “Culture and attractions — Attraction” type (see section 3.6.2.1.1. Item type).

Draw vegetation items of the “Park, square”, “Block vegetation”, “Nature reserve” and “Cemetery” types along the borders of their territories (fences, cemetery perimeter in the absence of a fence, administrative borders of protected areas) or vegetation borders (for example, where the vegetation meets a road). Internal polygons for these types of items are drawn only when a part of their territory constitutes a different item with a different purpose.

You don't need to pay special attention to rounding corners when drawing vegetation items.

Rounded:

Not rounded:

Beyond the territories of regularly developed areas, vegetation may intersect with motorways drawn using one line or railways.

Vegetation may intersect with motorways that run through territories that are regularly developed if those motorways have one of the following classes:

Both outside of and on territories that are regularly developed, vegetation of the “Park, square”, “Nature reserve” and “Cemetery” types may intersect with motorways of any type if these roads are exit ramps to these areas of vegetation or passages through said areas.

For example:

Roads and vegetation items located at different levels can intersect.

Also see also 3.3.1.1.8.

Lawns should be enclosed (by edging, curbs, fences, etc.). Draw the item outline based on the physical border of the section containing vegetation. For example:

Correct	Incorrect

Correct	Incorrect

Only draw lawns that are tended to. Land plots with damaged vegetation or that are not covered in greenery should not be drawn.

Fields, meadows, and empty lots are not classified under this type: don't draw these items on YME.

Draw “Urban vegetation” along the borders created by grass and trees/shrubs that were planted there.

In those cases, you can also map vegetation in detail: draw the grass cover as a “Lawn” item and shrubs and trees as “Urban vegetation” items:

Do not simplify urban vegetation polygons.

Roads drawn using two lines can not cut through a vegetation item: draw these items along both sides of such roads (i.e. the road divides the vegetation).

Borders of woodlands that are located along such roads should be drawn based on the actual vegetation borders (not based on the tree canopies) and should not intersect with the road.

When drawing the sections of polygonal hydrographic items that border vegetation items, follow these rules:

3.9.1.12.1

If the item's polygon is completely contained by the polygon of a different category of item (such as if a lake or pond is located within a forest), then only draw the polygon for the item located within the other item (in this case, the lake or pond) along their border. Don't draw internal polygons for map items containing other items (such forests where lakes are located). Take this same approach when drawing river polygons that intersect woodlands or other items:

3.9.1.12.2

If the item polygon partially overlaps with the polygon of an item from a different category (for example, if woodlands encroach on part of the course of a river), then draw the borders of both items and make sure that there are no gaps between the borders. Small overlaps between polygons are allowed, however:

Correct (borders merge)
Border of body of water:	Woodlands border:

Correct (borders merge)
Border of body of water:	Woodlands border:

On the resulting map, the map item borders will be merged:

Acceptable: small overlapping areas of polygonal items.

Unacceptable: gaps between bordering items.

Note.

For information on drawing overlapping border sections of composite polygonal items, see Section 2.7.4.1. Composite polygonal items: drawing techniques.

The polygons of different vegetation items shouldn't intersect. However, they can have shared borders.

“Woodlands” and “lawn” type vegetation items can exist inside “park, square”, nature reserve, and “cemetery” item polygons (those items are defined based on their use, similarly to “Territory” items).

If a “lawn” item is drawn inside a “park, square”, “nature reserve”, or “cemetery” item polygon, you can draw a “woodland” vegetation item inside it.

If a lawn item is drawn inside a park, square, nature reserve, or cemetery item polygon, you can draw an urban vegetation item inside it.

Vegetation items should not intersect (overlap) with buildings (except for buildings located completely within the borders of vegetation items that are not located in areas of regular development).

You should not add new external polygons to un-named vegetation items: drawing such polygons usually leads to mapping errors.
