1. Cross-line shot interpolation
synthesize by in-line interpolation
for a conventional-resolution 8-cable triple- source geometry, we have 100-m cross-line source spacing to interpolate
for a high-resolution survey, we have 50-m cross-line source spacing to interpolate

2. Cross-line shot interpolation
similar to in-line interpolation, but...
we only have 3 traces (not 4) as input
two have correct offset and azimuth
but the last does not have the correct CDP
more difficult than in-line

3. cross-line interpolation
original data

4. cross-line interpolation
recovered data from 100 m

5. cross-line interpolation
error

6. cross-line interpolation
original data

7. cross-line interpolation
recovered data from 50 m

8. cross-line interpolation
error
