Can anybody explain to me the meaning of images 1, 2, 4, 5, 7, 8, 10, 11 in sidewalk dat?

Another thing:
can sidewalks have a winter image?

in slopes, what does the second index [0] mean? animation? climates? summer/winter?

This value refers to "artificial wall" (eg bricks, concrete) or "natural wall", I do not know, which one is indicated by [ 0] and [ 1].
