1:50,000. However, cadastral level (1:8,000 or larger) 
mapping can be undertaken wherever necessary for a 
specific area using 1:50,000 scale soil map as map base. 
Aerial photographs or high resolution satellite data 
(panchromatic at 2.5 m or larger resolution and multi- 
spectral at 10 m or larger resolution) which would be 
available in future remote sensing satellite systems could 
be used for cadastral mapping of soils and land 
degradation (1:8,000 or larger).
