Germany Residential discontinuous urban fabric
Ribbon-built villages 112 / 2xx
Ribbon-built villages (‘Straßendörfer’ and ‘Hufendörfer’) in a width of 100 m are registered if the gaps between the buildings are below 100m (StBA, 1996)
Small discontinuous urban fabric areas less than 25 ha are grouped together, if the distance between each of them is less than 300 m in order to reach 25 ha. The exterior contour line leans on road network (BOSSARD ET AL., 2000) If equal / similar extension in 1990: use polygon of 2000 and assign 112 in 1990 as well
If increased polygon area (change): Indicate change by polygons to 1990 status (if extension > 25 ha in 1990). If extension in 1990 below 25 ha: keep old assignment but mark by a flag (NRCH=1) that no real change in full extent happened to CLC2000. University areas / hospitals etc. 112 / 121
Function of living is dominant, uni- versity areas and military living buildings and administration build- ings are included in 112.
Military objects with non-residential use are in class 121. (StBA, 1996)
Hospitals, universities, schools are included in 121 (BOSSARD et al, 2000). Delineate obvious big complex areas of universities / hospitals stable in 1990 / 2000 to 121 (detailed differentiation not possible), focus on changes.
Large blocks of
flats, with green spaces be- tween 111 / 112
Typical for 112: one-family houses and ribbon buildings; large blocks with large green between buildings in 112, with small green in 111, no- tice sealing value 80% (StBA, 1996)
Large blocks of flats, where green spaces, parking areas and adventure playgrounds cover significant surface area, to 112 (BOSSARD et al, 2000)
Road and rail networks and associated land Road and rail net-
works 122 / 121
122 consists mainly of: railway sta- tions and marshalling yards, motor way crossings, parking areas (no info on priorities) (StBA, 1996)
Railways have a higher priority than urban fabric does, roads have a lower priority (BOSSARD et al, 2000)

Germany Airports
Sport airports will be classified as 124, if airport infrastructure (fortified runways, passenger terminals, halls, etc.) is visible (BOSSARD et al, 2000)
Sport airports 124 / 142
Sport airports with asphalted run- ways in 124; without asphalted run- ways, when they can be detected in the satellite imagery (StBA, 1996)
Small airfields are to be classified as 142, if airport infrastructure is not visible (BOSSARD et al, 2000)
Sport and leisure facility Allotment gardens 142 / 242
Allotment gardens: Camping, sports fields, sport stadium, leisure parks, public parks out of urban ar- eas, as well as allotment gardens, in 142 (StBA, 1996)
Allotment gardens: Contribution due to major use (142 if mainly leisure facility, 242 if mainly used for vegetable / fruit production) (BOSSARD et al, 2000)
Mineral extraction sites Mineral extraction sites / artificial lakes
131 / 512
Artificial lakes by extraction („Bag- gerseen“) are completely registered as mineral extraction sites if on the biggest part of the area an active extraction of gravel or sand can be recognized (no limitation in size) (StBA, 1996)
In CLC2000, delineate and assign min- eral extraction sites and artificial lakes due to their area portions (BOS- SARD et al, 2000)
Adapt in 1990. Remain assignment to 131 in CLC1990, unless water domi- nates (~ 80 - 90%).
Non-irrigated arable land / Fruit trees and berry plantations / Vineyards Hop plantations
211 / 222
Hop plantations are registered as arable land (StBA, 1996)
Hop plantations: To be integrated in 222 if > 25 ha (BOSSARD ET AL., 2000).
To be checked which additional informa- tion available.
Nursery gardens of fruit trees and shrubs
Nursery gardens if detectable as fruit trees nurseries: 222, if uncertain / mixed: 211 (BOSSARD et al, 2000). Nursery gardens of
wine and fruit trees 222 / 221 / 211
wine-growing nurseries
If detectable as wine-growing nurser- ies: 221, if uncertain / mixed: 211 (BOS- SARD et al, 2000)

Germany Transitional woodland and shrub
Transitional wood- land, shrub 324
Transitional Woodland 324 was used not in transient states in for- estry, but mainly for shrub areas with single trees or tree groups to be find on:
- Uncultivated former vineyards - Military training areas
- Fallow land of former track sys- tems, industrial areas, extraction sites, deposits
- Woodland areas near the timber- line with high portions of shrub - Areas strongly affected by forest
decline (totally tree-less areas were mainly assigned to 322) (StBA, 1996)
Transitional woodland / shrub for - Clear cuts in forest areas,
- Young plantations,
- Heavily damaged forests by wind, snow-brake or acid rains and other pol- lution with more than 50% dead trees (BOSSARD et al, 2000)
In CLC2000: Delineate large forest ar- eas heavily destructed (e.g. by storm) as 324. Integrate large young reforestation and afforestation in 324, especially on former non-forest areas (former military areas).
Prefer 324 instead of 322 for mixed vegetation cover.
In CLC90: Integrate status also in CLC1990, especially for large areas and for transient states of former non-forest areas (e.g. former military areas). Water bodies
