GROUP: other sealed (os)
DEFINITION:assorted sealed, compacted, or managed surfaces not built-up with covered structures, not directly associated with buildings.

1. Object
   1. generic sealed areas: not built for structures/ transportation/ irrigation/recreation/ graves = sealed surfaces including crushed stone or other crushed impermeable materials used as a surface.
   2. grave with >75% sealed area
   3. sealed surface used for drying = not directly associated with buildings.
   4. small parking lot, separate from building features = small parking lots (<30m), only mapped and classified as a separate feature if separated from building features by a >2m linear or >5m areal soft feature. Otherwise included as part of building features. Sealed surfaces include crushed stone or other crushed impermeable materials used as a surface.
   5. recreational paved surfaces: playground/ basketball court/tennis courts/playground with impermeable or gravel cover.
   6. sealed water basin = swimming pools, fountains, sealed ornamental or recreational water basins or ponds.
   7. sealed surface used for industry = sealed surface used for some form of industrial production, such as the preparation of concrete building frames or the storage and processing of coal, sand, recycling materials or other materials.
   8. large parking lot, may adjoin or encircle other builtup features = larger parking lots (>30m), that are not included as part of other builtup or building features, even if they encircle or adjoin other builtup features. Sealed surfaces include crushed stone or other crushed impermeable materials used as a surface.
   9. recreational improved permeable surfaces = playgrounds or other prepared surfaces with permeable cover, such as mulch, or managed bare compacted earth such as baseball diamonds.

1. generic sealed areas: not built for structures/ transportation/ irrigation/ recreation/ graves = os01
2. grave with >75% sealed area = os02
3. sealed surface used for drying = os03
4. small parking lot (<3om), separate from building features = os04
5. recreational paved surfaces: playground/ basketball court/… = os05
6. sealed water basin = os06
7. sealed surface used for industry = os07
8. large parking lot (>30m), may adjoin or encircle other builtup features = os08
9. recreational improved permeable surfaces = os09

1. IF unclear whether a large parking lot (area >30m (1000m2), that adjoins or encircles other builtup features is large enough to map and classify as a separate feature, because it is similar in size to the builtup features, then map and classify it as a separate os08 parking lot feature.
