Rendering natural=blockfield #5

The value blockfield for tag natural is relatively new (300 uses so far, see https://wiki.openstreetmap.org/wiki/Tag:natural%3Dblockfield) but it definitely fills a gap for boulder areas such as Fontainebleau forest in France (see https://commons.wikimedia.org/wiki/File:Fontainebleau_place_cuvier.jpg, https://www.openstreetmap.org/way/1216929655).

Replacing inappropriate tagging as scree or bare_rock should increase the numbers reasonably fast in the future.

It would definitely help the process of sorting out these tag values if natural=blockfield was rendered with a specific pattern in the Topo map.

A peculiarity of this type of area is worth mentioning: it can coexist with a forest, where the trees grow between blocks or even sometimes on the blocks. This might require special care when rendering.

Thank you. Unfortunately, the picture above looks more like 'natural=stone' than 'block field'. For an image of a block field, please see the 'natural=blockfield' article on the OSM wiki.

It's actually difficult to find a proper photograph of the blockfield I gave as an example, half-hidden as it is under the trees. Here is an old picture from before the trees grew.

From wikipedia https://en.wikipedia.org/wiki/Blockfield there is also some description. They are indeed different from scree or bare_rock. Will add support for it.
