Is there a specific tag or method for mapping terraced farmland? In areas with any amount of slope, terraces are built so that areas of cropland can be flood irrigated. This is very common in rice-growing regions, and also used for some other crops which grow best in flooded land.
The presence of irrigation might be tagged with "irrigation=yes" - this has been used about 1600 times in combination with landuse=farmland (See https://taginfo.openstreetmap.org/tags/irrigated=yes and https://overpass-turbo.eu/s/ZQq). And "crop=rice" is widely used for areas where rice is routinely grown each year. But what about the fact that the farmland is built in terraces? Is there an existing way to map this? There is a key "farmland" with about 100 uses of "farmland=terraced" and a few of "farmland=paddy" (for rice paddies). Apparently I used this tag myself a half-dozen times: https://www.openstreetmap.org/way/587624037#map=17/-4.05357/138.92747 Example from Nepal, with aerial imagery in iD: https://www.openstreetmap.org/edit?way=343286016#map=17/28.01034/84.61103 If a mapper wanted to show every terrace in detail, what would be the best option? Perhaps man_made=embankment between each layer? -- Joseph Eisenberg
