- interpretation of land use impossible Ti 
- plot outside image sd2 
- plot outside control zone T3 Doubtful for technical reasons : 
- plot covered by clouds T4 take declared area and declared 
- plot without cartographic reference . T5 land-use 
- plot limit problem not solved on the image T6 
- declared to be less than 0.3 ha T7 
(Technical limit of remote sensing using satellite images) 
- area measured less than 0.3 ha A1  |take measured area 
- plot declared in more than one application |A2 
(A2 is only assigned where the total declared area exceeds p 
the total area of the plot) 
- declared as rotating set-aside but found to be A3 give zero value to disputed area 
another land-use 
- plot found to be ineligible in reference periods A4 
- declared as one crop group but found to be C1 assign the observed land-use, give zero 
another : value to disputed area 
- declared as one crop group but found to be C2 divide plot and apply previous rules to 
more than one measured area 
- land-use found as declared C3 take found area and land-use
