Website to generate polygons for recursive relations in OpenStreetMap

Using this tool, you can get latest polygons from OSM, optionally simplified using PostGIS.

Features

• Update geometry based on the latest OSM data
• Preserve multiple geometries between sesssion
• Simplify each shape using PostGIS ST_Buffer(ST_SimplifyPreserveTopology(ST_Buffer(ST_SnapToGrid(st_buffer(geom, %s), %s), 0), %s), 0))
• For every version of the relation:
• Display shape of polygon using image
• Basic stats (number of nodes, lenght)
• Export to WKT, poly and GeoJSON
• More
