Correlation: Making the correlation between the field data and the interpretation.
From the correlation between collected field data and the interpretation, the entire area
can be mapped in terms of what is on the ground. If there is a good correlation, only recoding and renaming of the units will be required. If the correlation is poor, however, a complete re-interpretation might be needed, after carefully restudying the legend in terms of interpretation elements. For producing the final map, all aspects of map design and cartographic finishing should be observed in the concepts of Visualization.
