Table 1
The evaluation standard of resolution and data.
| | Class | Resolution | Data rating |
| | A | Structural evaluation possible
(Verification tile spacing over 90% of total area) | Excellent data accuracy
(Scanning wall over 4 m) | | B | Possible to distinguish overall
(Verification tile spacing over 70% of total area) | Possible to distinguish the overall data
(Scanning wall over 3 m) | | C | Can be identified for some area
(Verification tile spacing over 50% of total area) | Data can be separated for some area
(Scanning wall over 2 m) | | D | Not identifiable overall
(Verification tile spacing over 30% of total area) | Poor data accuracy overall
(Scanning wall over 1 m) |
