LD’=L2+BHD+P-N*SCE or =L1+BHB+P-N*SCE
End of the Segment (B) definition:
The following variables are defined:
‣ L3 is equal to the first line of detector 1 (an odd one) on the track reference frame (in
km) of the last scene
‣ L4 is equal to the first line of detector 2 (an even one) on the track reference frame (in
km) of the last scene
‣ LF is equal to the last line of the product after coarse registration inter-dtc (in km)
‣ P is equal to the radiometric processing margin (in km).
Scene no k
interdetc. derg. (BHD) ~47km
onboard scene (SCE) ~23km
interband derg. (BHB) ~14km

L4=L3-BHD+BHB
LF=L4 + SCE –P = L3- BHD+BHB + SCE – P
Assumption: No scenes margin at the end
The Junction of between two segments A/B:
The following variables are defined:
‣ L3 is equal to the first line of detector 1 (an odd one) on the track reference frame (in
km) of the last scene (k) of segment A
‣ L4 is equal to the first line of detector 2 (an even one) on the track reference frame (in
km) of the last scene (k) of segment A
